<p><strong>In this technical tip from </strong><span><strong>Phenomenex</strong></span><strong>, the topic of gas chromatography (GC) column trimming is addressed from a troubleshooting perspective. The key question explored is whether trimming a GC column is necessary and how it impacts chromatographic performance.</strong></p><h3><strong>Why Trim a GC Column?</strong></h3><p>Column trimming is primarily used to <strong>restore chromatographic performance</strong> by removing damaged or contaminated sections, typically located at the column inlet.</p><h5><strong>1. Baseline Bleed, Noise, Ghost Peaks, Poor Peak Shape</strong></h5><ul><li><strong>Cause:</strong> Column contamination</li><li>Removing the contaminated stationary phase at the column entrance helps restore performance.</li></ul><h5><strong>2. Elevated Baseline (Especially at High Temperature)</strong></h5><ul><li><strong>Cause:</strong> Column bleed</li><li>Degradation of the stationary phase due to <strong>oxygen exposure or thermal damage</strong> leads to increased baseline.</li></ul><h5><strong>3. Ghost Peaks (Peaks Without Injection)</strong></h5><ul><li><strong>Cause:</strong> Residual sample or contamination</li><li>Compounds trapped at the beginning of the column can appear as peaks even when no sample is injected.</li></ul><h5><strong>4. Peak Tailing (Asymmetrical Peaks)</strong></h5><ul><li><strong>Cause:</strong> Damaged or contaminated column sections</li><li>These issues result in <strong>adsorption effects or poor flow dynamics</strong>.</li></ul><h5><strong>5.

Because several HAAs are associated with adverse health effects, their determination remains relevant in environmental and public health analysis. This interview highlights the academic pathway and research experience of Jessica, whose undergraduate work focused on the development of a gas chromatography–mass spectrometry (GC-MS) method for the analysis of HAAs in pool and hot tub water.</p><p>Her project emerged from a combination of academic interest in analytical chemistry, practical experience with water testing, and the constraints of instrument availability in an undergraduate research setting. The resulting workflow illustrates how method adaptation, critical problem-solving, and persistence can enable meaningful analytical research even when standardized methods are not directly accessible.</p><h4><span><strong>Academic Background and Entry into Analytical Chemistry</strong></span></h4><p>Jessica completed a Bachelor of Science in Chemistry with a minor in Physics at Thompson Rivers University in British Columbia. Her interest in analytical chemistry developed during her second year of study, when coursework revealed the quantitative and detail-oriented nature of the discipline. This emphasis on numerical interpretation, precision, and method development aligned strongly with her academic strengths and motivated her to pursue analytical research.</p><p>Her specific interest in water chemistry originated even earlier through practical work in a pool and hot tub store, where she became familiar with routine water testing and the chemical factors influencing water quality. This early exposure led naturally into undergraduate research under the supervision of Dr. Sharon Brewer, whose expertise in water analysis provided an ideal foundation for the project.</p><h4><span><strong>Haloacetic Acids as Disinfectant Byproducts</strong></span></h4><p>Haloacetic acids are a subset of disinfectant byproducts generated when sanitizing agents react with natural organic matter in water. In treated recreational water systems such as pools and hot tubs, disinfectants are essential for microbial control, yet they can also lead to formation of unwanted chemical byproducts. Because some HAAs are considered potentially harmful, their occurrence and concentration warrant analytical attention.</p><p>In this study, both chlorinated and brominated HAAs were of interest. Although the tested water systems were primarily sanitized using chlorine-based products, the occurrence of brominated HAAs emerged as a notable and somewhat unexpected finding.</p><h4><span><strong>Analytical Challenges and Method Selection</strong></span></h4><p>A major challenge in the project was the lack of access to the instrumentation required for the standard EPA-based method initially considered for HAA analysis. The available protocol depended on GC-ECD instrumentation, which was not accessible at the university. This limitation required the development of an alternative strategy based on the instruments available locally.</p><p>GC-MS was selected as the most practical analytical platform. To support this approach, Jessica identified a literature source describing a similar method that could be adapted to her research aims. In parallel, dispersive liquid–liquid microextraction was introduced into the workflow as a means of sample preparation, providing valuable methodological experience beyond the standard undergraduate laboratory curriculum.</p><p>This adaptation illustrates a common reality in academic research: analytical methodology is often shaped not only by ideal regulatory procedures, but also by local instrument access, scheduling limitations, and the practical needs of the researcher.</p><h4><span><strong>Need for Derivatization in GC-MS Analysis</strong></span></h4><p>A central analytical issue was that HAAs are inherently nonvolatile, which makes them poorly suited to direct GC analysis. To enable gas chromatographic separation, derivatization was required to convert the analytes into more volatile derivatives with more favorable boiling characteristics.</p><p>In this method, derivatization with octanol was employed. This modification improved volatility and also generated larger fragments, which aided mass spectral interpretation by making the analyte fragmentation patterns easier to distinguish. Thus, derivatization served both chromatographic and mass spectrometric purposes.</p><h4><span><strong>Optimization of the GC Temperature Program</strong></span></h4><p>Considerable effort was devoted to optimization of the GC temperature program. The main difficulty did not arise solely from the analytes themselves, but from the derivatization reagent. Octanol produced a broad and persistent chromatographic feature, including a significant shoulder extending into later retention times. This complicated separation and increased pressure to keep the method sufficiently short for routine sample throughput.</p><p>Among the analytes, monochloroacetic acid proved especially problematic. Because it differed only subtly in structure and produced overlapping behavior relative to the octanol-derived background, its signal was difficult to isolate confidently. Although chlorine-containing fragments could be observed, precise assignment remained challenging. This difficulty underscores how small structural differences and matrix-related interferences can complicate quantitative GC-MS workflows.</p><h4><span><strong>Method Performance and Practical Advantages</strong></span></h4><p>Although the adapted GC-MS method was developed out of necessity, it also provided practical advantages over the more standardized workflow that had initially been considered. In particular, the derivatization step in the adapted approach required only approximately 10 minutes, whereas the more conventional procedure involved a water bath step lasting around two hours. In addition, the adapted workflow offered shorter overall preparation and analysis timing, allowing batches of samples to be prepared and placed on the autosampler within a normal working schedule.</p><p>From a practical research perspective, this translated into substantially improved laboratory efficiency. The ability to complete derivatization quickly and begin automated sample analysis without extensive delays made the workflow more manageable and better suited to the demands of an undergraduate project.</p><h4><span><strong>Unexpected Findings: Brominated HAAs in Chlorine-Sanitized Systems</strong></span></h4><p>One of the more surprising outcomes of the study was the predominance of brominated HAAs, despite the fact that the investigated pools and hot tubs were sanitized using chlorine-based treatments. Four of the systems relied on sodium chloride electrolysis to generate chlorine species, while others used chlorine-containing puck formulations commonly applied in recreational water treatment.</p><p>Given these conditions, higher levels of chlorinated HAAs might have been expected. Instead, the results suggested a greater abundance of brominated HAAs. A plausible explanation is the presence of bromine-containing impurities in commercial pool and hot tub chemicals. Although such impurities may occur at relatively low levels, they can still influence disinfectant byproduct formation. The observation highlights the importance of considering the full chemical composition of treatment products, not merely their primary declared active ingredients.</p><h4><span><strong>Value of Practical Industry Experience</strong></span></h4><p>Jessica’s prior work in the pool and hot tub industry provided an unusually strong contextual advantage for the project. Because the samples originated from store clients, she had access to detailed information about the chemicals used in each system, including safety data sheets and knowledge of treatment timing. This background significantly strengthened interpretation of the analytical results by linking measured byproducts to known product usage patterns.</p><p>Such integration of practical field knowledge with laboratory analysis represents an important strength in applied environmental chemistry, particularly when studying real-world water systems rather than idealized laboratory samples.</p><h4><span><strong>Scientific Development and Early Research Motivation</strong></span></h4><p>An especially valuable element of the project was the role it played in building research confidence. Jessica described the first successful identification of an analyte peak as a memorable turning point, reflecting the emotional significance of early experimental success in scientific training. In analytical chemistry, where method optimization often involves repeated setbacks and ambiguous data, such moments can be critical in sustaining motivation and reinforcing scientific identity.</p><p>This experience also informed her advice to early-stage researchers: unfavorable or unexpected outcomes still constitute valid results. Negative or imperfect findings remain analytically meaningful and contribute to scientific understanding, provided they are interpreted carefully.</p><h4><span><strong>Connection to Current Research</strong></span></h4><p>Jessica is now working at the University of Calgary on a different project focused on ozone and nanobubble disinfection. Although the analytical platform and immediate research questions have changed, the conceptual connection to her earlier work remains clear. Her experience with disinfectant byproducts and water chemistry directly supported her transition into this new role and helped position her as a strong candidate for research in water treatment-related systems.</p><p>She also expressed interest in expanding her analytical expertise through ion chromatography, which will play a role in her current work. This transition reflects the broader development of an environmental analytical chemist whose work continues to center on water quality, disinfection chemistry, and the analytical tools needed to investigate both.</p><h4><span><strong>Public Health Relevance</strong></span></h4><p>A notable practical implication of the project concerns recreational water safety. Jessica emphasized that pool and hot tub water should not be ingested, a recommendation already widely understood in general terms but further reinforced by her findings. In at least one case, HAA concentrations were reported at levels far above the federal drinking water regulation threshold. While such regulations are designed for potable water rather than recreational water, the comparison nevertheless illustrates the extent to which disinfectant byproducts may accumulate in these environments.</p><p>She also noted that several HAAs are classified as probable human carcinogens, with prolonged exposure linked to serious health concerns. Although occasional accidental ingestion is not equivalent to chronic exposure, the findings reinforce the importance of appropriate hygiene, safe water maintenance practices, and awareness of chemical byproduct formation in recreational systems.</p><h4><span><strong>Conclusion</strong></span></h4><p>This research demonstrates how meaningful analytical chemistry can emerge from a combination of scientific curiosity, practical constraints, and strong mentorship. By adapting a GC-MS workflow for the determination of haloacetic acids in pool and hot tub water, Jessica developed a method that was both workable within local instrument limitations and efficient enough to offer practical benefits over more conventional procedures.</p><p>Beyond the analytical results themselves, the project highlights several broader themes: the value of undergraduate research, the importance of flexibility in method development, the benefit of practical contextual knowledge, and the relevance of environmental analytical chemistry to real-world public health questions. It also shows how early research experiences can shape a long-term scientific trajectory, leading from undergraduate investigation to continued work in water chemistry and disinfection science.</p><blockquote><p><strong>This text has been automatically transcribed from a video presentation using AI technology.

Bruker: How to Utilize FT-IR for the Analysis of Coatings, Surface Treatments and Technical Cleanliness

How to Utilize FT-IR for the Analysis of Coatings, Surface Treatments and Technical Cleanliness.

In this webinar, our surface analysis expert Eric Klein will take you to his lab and work through typical examples of industrial surface analysis. 

Using FT-IR for Coatings, Surface Treatments & Cleanliness

<p><strong>A standard ATR measurement using FT-IR technique for the mid IR spectral range usually lasts a few seconds to half a minute. This is very convenient and fast for identification, verification of substance or similar routine analysis. But when it comes to applications, for which temporal resolution is required, e.g. kinetics studies, reaction monitoring, identification and separation of intermediate species or characterization of pulsed laser, time-resolved FT-IR spectroscopy (TRS) is mandatory.</strong></p><p>With up-to-date electronics, long-time experience and knowhow, Bruker as a FT-IR manufacturer can provide research spectrometers achieving a temporal resolution of a few ms , µs or even ns, depending on the applied TRS technique. The rapid-scan technique is limited to a time resolution in the low millisecond range and is widely used to characterize the kinetics of single shot chemical reactions. For repetitive kinetics, step-scan overcomes these limitations and reaches a time resolution down to the low nanosecond range. Interleaved TRS is a technique applicable to a certain class of repetitive kinetics, where the measurement time is used much more efficiently compared to step-scan. A Bruker research spectrometer can be equipped with all above TRS options. Depending on the application and the required temporal resolution, one of these options can be applied.</p><p>In the upcoming free-of-charge two-part webinar about TRS techniques you will learn about the functional principles, practical handling, instrumental setups and application fields of the time-resolved FT-IR techniques.</p>

<div><p><strong>Thermal gravimetric analysis (TGA) is an ideal tool for the characterization of all kinds of organic and inorganic solids and liquids. Thermodynamic transitions, thermal stability, decomposition and chemical reactions can be detected and quantified with high accuracy over a broad temperature range. However, this method does not provide details about the chemistry behind the processes under study</strong>.</p><p>The combination of thermal analysis with infrared spectroscopy bridges this analytical gap. Fourier-Transform Infrared (FT-IR) spectroscopy is a classical tool for the identification and quantification of gases. This technique is based on the interaction of infrared radiation with the vibrating dipole moments of molecules. FT-IR yields a unique IR spectrum for each substance, except for homonuclear diatomic gases and pure metals</p><p>In a simple case, only one type of gas molecule is evolved with an applied temperature increase in the TGA. The evolved gas is flowed into the FT-IR and can be readily identified by searching its spectrum against a gas phase reference library. In a typical decomposition process, evolved fume is a mixture of gases. Different hardware and software approaches to identify the composition of complex gas mixtures will be presented with a thorough discussion of the following topics:</p><ul><li>Mixture analysis using library search</li><li>TGA-IR at reduced pressure&nbsp;</li><li>Spectra manipulation method for deconvoluting complex spectra (mixtures)</li></ul><p>Examples of applications will include the identification of plasticizers in polymers, PVC undercoating analysis, decomposition of&nbsp;PETN explosive, NHF propellant, and others.</p><blockquote><p><strong>Presenter: </strong>Dr. Sergey Shilov (North America Product Manager, Science Business Unit, Bruker Optics)</p><div><p>Dr. Sergey V.
