Exploring Alternatives to Rotary Evaporation in Modern Laboratories

Wastewater treatment plants struggle every day with substances that don’t simply disappear from the water. The removal of nitrogen compounds is very important at these plants. If too much of these substances remains in the water, they harm rivers and the life within them. <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/article/5403">Karel Havlíček </a>from CXI TUL was a co-investigator on the HYMNA project, which combined two well-known treatment technologies into a single system. And he added something to them that isn’t commonly used at treatment plants: nanofibers.The full name of the project is “Hybrid MBR-MBBR System Using Nanomaterials for Advanced Wastewater Treatment.” The acronym is HYMNA. “It sounds a bit grand,” laughs co-investigator Karel Havlíček from the Department of Environmental Protection Technology. But the goal was indeed grand. The water that flows out of a treatment plant isn’t always as clean as it could be. And that’s a problem worth solving.<h4>A Screen and Beads</h4>Behind the acronyms MBR and MBBR lie two technologies that treatment plants typically deploy separately. But Karel combined them into a single process and demonstrated that together they can work significantly better. He validated the combination in practice and used it to design a technology with a clear procedure, measurable results, and the potential for real-world application.The MBR functions as a fine screen. The membranes trap impurities, organic matter, and undissolved particles. But even then, the process isn’t complete—nitrogenous compounds still remain in the clarified water.To address this, Karel Havlíček and his partners implemented the second part of the technology: MBBR. Small plastic beads with holes and nanofibers inside move freely in the tank with the help of aeration. Microorganisms grow and live on the surface of the nanofibers, converting ammonia nitrogen into nitrates.Why does this matter? Ammoniacal nitrogen is toxic to fish; it damages their gills and, at higher concentrations, kills them. An excess of nitrogen triggers algae blooms, causing the water to turn green, depleting oxygen levels, and suffocating aquatic life.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Kulicky_s_nanovlakennym_srdcem_Takhle_se_da_cistit_voda_lip_2_6559ff2373.jpg" alt="CXI TUL: Beads with a nanofiber core.

Karel inserted nanofiber carriers—a fine fibrous material to which microorganisms quickly and firmly attach—into plastic bodies with holes. He had already proposed this concept in his dissertation.The path to the final design was not straightforward. Originally, it was a nanofiber layer. However, it gradually washed off the beads. They replaced it with yarn, which holds its shape. The result is a utility model for new biomass carriers.The main advantage is the speed of colonization. On conventional materials, colonization takes much longer. Microorganisms colonize the nanofibers quickly. This is crucial, especially where the water is hostile or toxic to them.Industrial wastewater is often so polluted that bacteria cannot survive on conventional carriers. On a nanofiber surface, however, they manage to attach themselves before the environment destroys them. The system then works even where other technologies would fail.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Kulicky_s_nanovlakennym_srdcem_Takhle_se_da_cistit_voda_lip_3_290e60625f.jpg" alt="CXI TUL: Beads with a nanofiber core.

The team even tested extreme concentrations of up to eighty milligrams per liter. And that’s not just fine-tuning. That’s a stress test pushing the limits—one that could cripple or completely halt the activity of the purifying microorganisms.The system handled it. At the outflow, they measured less than one milligram per liter.“We achieved a level that even a conventional treatment plant often can’t handle,” Karel said, expressing his surprise.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Kulicky_s_nanovlakennym_srdcem_Takhle_se_da_cistit_voda_lip_4_00a10f7915.jpg" alt="CXI TUL: Beads with a nanofiber core.

The system can function not only as a post-treatment unit following a standard treatment plant but also as a standalone modular treatment plant. No construction is needed; the system can be delivered, connected, and put into operation.“Industrial facilities will especially appreciate this. Companies that currently transport contaminated water in barrels as hazardous waste could handle part of the treatment themselves,” explains Karel. According to him, this would mean less waste, less logistics, and lower costs for companies.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Kulicky_s_nanovlakennym_srdcem_Takhle_se_da_cistit_voda_lip_5_15c7bfefc3.jpg" alt="CXI TUL: Beads with a nanofiber core.

The micropollutants simply accumulate in the system,” Karel states. The system captures them but does not destroy them. That requires more powerful methods, such as ozone or UV radiation.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CXI_TUL_Kulicky_s_nanovlakennym_srdcem_Takhle_se_da_cistit_voda_lip_f8251f3b2e.jpg" alt="CXI TUL: Beads with a nanofiber core.

In this episode of Concentrating on Chromatography, we sit down with Dr. Lee Polite from Axion Training Institute to break down one of analytical chemistry's most powerful yet misunderstood techniques: gas chromatography-mass spectrometry (GC/MS).<h4>What You'll Learn:</h4><ul><li>Why GC and MS are the "perfect pair" – and what happens when you try to use MS alone</li><li>The electron gun: how molecules get ionized and why they become positively charged (not negatively!)</li><li>The magnetic sector vs. quadrupole: from first principles to modern mass filtering</li><li>Why Dr. Lee uses the "corkscrew trajectory" analogy – and why it actually works</li><li>The cars and boats analogy: how fragmentation creates a unique molecular fingerprint</li><li>Scan mode vs. SIM (Selected Ion Monitoring): when to use each for identification vs. sensitivity</li><li>Real-world forensics: detecting pesticides in spinach and cocaine in hair follicles</li><li>Triple quad GC/MS and Multiple Reaction Monitoring (MRM): the future of trace analysis</li></ul><h4>Why This Matters:</h4>Over 2 million chromatographs operate worldwide, yet most users don't truly understand how they work. Dr. Polite has trained more than 14,000 professional scientists at Axion Labs to move beyond "pushing buttons" to genuinely comprehending the science. This conversation is designed for undergraduate students, academic researchers, and anyone preparing for analytical chemistry roles in pharma, environmental testing, or forensics. &nbsp;🎤 Dr. Lee Polite is a leading authority in analytical chromatography education and founder of Axion Training Institute, a real working laboratory where scientists come for hands-on GC and LC training. With nearly 30 years of experience and a PhD under Harold McNair (one of the grandfathers of modern chromatography), Dr. Polite is passionate about making complex instrumentation accessible to students and professionals alike.<h3>Video Transcription</h3>Mass spectrometry has a reputation for being one of the most intimidating analytical techniques. According to Dr. Lee Polite, however, that reputation is undeserved. During a recent interview, the founder of Axion Analytical Labs shared how decades of teaching scientists—from undergraduate students to forensic chemists and even lawyers—have convinced him that virtually anyone can understand GC/MS when the concepts are explained correctly.His approach relies less on equations and more on analogies, transforming complex physical principles into familiar everyday experiences.<h4>The biggest misconception about mass spectrometry</h4>"The first obstacle isn't the science—it's the belief that you'll never understand it."That is the misconception Dr. Polite encounters most often. Students frequently enter chromatography or mass spectrometry courses assuming the subject is too complex for them.His advice is simple: suspend that disbelief.Rather than viewing GC/MS as one enormous complicated system, he encourages learners to see it as a collection of simple processes connected together. Once each individual step becomes clear, the entire instrument suddenly makes sense.<h4>Teaching more than 14,000 scientists</h4>Dr. Polite founded Axion Analytical Labs nearly three decades ago. Although it operates as a fully functional chromatography laboratory, its primary mission is education.Scientists spend five days in the laboratory learning chromatography hands-on—disassembling instruments, rebuilding them, troubleshooting problems, and developing a practical understanding of how the technology works.Over the years, Axion has trained more than 14,000 scientists, along with hundreds of attorneys who need to understand analytical chemistry for courtroom testimony. Dr. Polite believes curiosity matters far more than formal education.<h4>Why every GC needs a mass spectrometer—and every mass spectrometer needs a GC</h4>One of the interview's clearest explanations addresses a question many beginners ask:<h5>Why do we combine gas chromatography with mass spectrometry?</h5>The answer lies in the strengths and weaknesses of each technique.Mass spectrometers excel at identifying pure compounds, but they struggle with complex mixtures. Real-world samples—environmental extracts, food, pharmaceuticals, forensic evidence—are almost always mixtures.Gas chromatography solves this problem by separating the mixture into individual components before they reach the mass spectrometer.As Dr. Polite summarizes:<blockquote>GC provides the separation power. Mass spectrometry provides the identification power.</blockquote>Without chromatographic separation, overlapping compounds generate confusing spectra that are difficult—or impossible—to interpret correctly.<h4>Explaining chromatography with a shopping mall</h4>Perhaps Dr. Polite's most famous teaching analogy compares chromatography to walking through a shopping mall.Imagine two people standing on a moving walkway. One walks straight through the mall, while the other repeatedly leaves the walkway to browse clothing stores, shoe stores, and accessory shops.Although both entered together, they exit at different times.Chromatographic separation works in exactly the same way. Every compound enters the column simultaneously, but molecules interact differently with the stationary phase. Those with stronger interactions spend more time "shopping" and therefore elute later.The analogy immediately illustrates retention time without requiring advanced chemistry.<h4>How can a mass spectrometer "weigh" molecules?</h4>Another concept that often confuses students is molecular weight determination.Since molecules are far too small to weigh directly, mass spectrometers first convert neutral molecules into ions using electron impact ionization.Once charged, the ions can be manipulated by electric or magnetic fields.Dr. Polite introduces the concept by first describing the historical magnetic sector instrument before moving to the quadrupole mass filter used in most modern GC/MS systems.His explanation replaces intimidating mathematics with a simple idea: only ions having the correct mass-to-charge ratio can successfully travel through the quadrupole and reach the detector.<h4>Fragmentation: the molecular fingerprint</h4>Simply measuring molecular weight rarely identifies a compound uniquely.The real power of GC/MS comes from fragmentation.High-energy electrons break molecules into characteristic fragments that create a unique mass spectrum—a molecular fingerprint.To explain this process, Dr. Polite asks readers to imagine a car packed with explosives. After the explosion, investigators identify the vehicle by examining scattered components such as wheels, doors, and the steering wheel.Mass spectrometry works the same way.Each fragment contributes evidence that allows software libraries, such as NIST, to determine compound identity with remarkable confidence.<h4>Scan mode versus SIM mode</h4>The interview also explores the practical difference between scan acquisition and Selected Ion Monitoring (SIM).Scan mode records a complete mass spectrum and is ideal for identifying unknown compounds.SIM, on the other hand, focuses only on a few selected ions, dramatically increasing sensitivity.Using pesticide analysis as an example, Dr. Polite demonstrates how compounds that are almost invisible in full-scan chromatograms become obvious when monitored using SIM.<h4>Why triple quadrupoles dominate trace analysis</h4>For laboratories measuring contaminants at parts-per-trillion concentrations, triple quadrupole instruments provide another major advantage.Instead of monitoring only a single ion, tandem MS follows a specific fragmentation pathway—known as a transition—greatly reducing background interference.This Multiple Reaction Monitoring (MRM) approach enables highly selective quantification of pesticides, PFAS, pharmaceutical residues, and numerous other trace contaminants in extremely complex samples.<h4>The chromatography lesson many users forget</h4>One message appears repeatedly throughout the interview:Most GC/MS problems are actually chromatography problems.Poor separations inevitably produce poor mass spectra.Dr. Polite argues that successful mass spectrometry begins with understanding chromatography fundamentals rather than relying on sophisticated detectors to compensate for inadequate separations.<h4>Looking ahead</h4>When asked about the future of mass spectrometry, Dr. Polite predicts continued improvements in sensitivity, smarter software, and increasing use of artificial intelligence.AI could assist laboratories by automatically recognizing problematic chromatographic peaks, identifying developing instrument issues, and simplifying interpretation of increasingly complex datasets.Yet despite these technological advances, he believes the fundamentals remain unchanged.Scientists who understand chromatography, ionization, fragmentation, and data analysis will continue to benefit regardless of how instrumentation evolves.<h4>Final thoughts</h4>After teaching analytical chemistry for more than 30 years, Dr. Lee Polite remains convinced that mass spectrometry is not inherently difficult.The challenge is rarely the science itself—it is finding the right explanation.By combining memorable analogies with practical laboratory experience, he demonstrates that one of analytical chemistry's most powerful techniques can also be one of its most approachable.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

Following up from our very successful previous sessions, we are delighted to offer another panel discussion in the ever-popular “Ask the Agilent Experts” series.Have you ever had a question about your GC/GCMS analysis and thought, “I have no idea what to do,” or that since the question seemed so simple, everyone must already know the answer and “Am I the only one who doesn’t know what to do?” We can assure you that you are not alone.If you have a question, we can guarantee that you are not the first…nor the last person to ask the question, especially when it comes to gases. Sometimes the simplest of questions can have the most complex answers. A question about the leaks on your mass spectrometer can lead to a discussion about how gas quality impacts sensitivity. A question about what to do when converting a method from helium to hydrogen carrier gas can lead to a discussion about column dimensions, column bleed, and what thermal stability means. There’s no such thing as an easy answer because the answer always depends on many different factors.Experts from Agilent, as well as from the field, will discuss some of the most frequently asked questions about GC and GCMS (which may seem like simple questions but have anything but simple answers). We'll also answer new questions that we hope you will submit to us.By attending this webinar, you will learn:<ul><li>How different carrier gases impact results and what to consider when converting methods from one carrier gas to another.</li><li>What is column bleed, how it relates to thermal stability, how your carrier gas can impact it, and why it matters even when using selective detectors like mass specs.</li><li>What is the difference between gas cylinders and gas generators, and should you consider using gas saving measures when using a generator.</li></ul>What you need to know:Date: 7th November, 2024Start times:<ul><li>Broadcast #1: 7th November - 7:00 PST (Los Angeles) / 9:00 CST (Chicago) / 10:00 EST (New York) / 15:00 GMT (London) / 16:00 CET (Paris/Berlin)</li><li>Broadcast #2: 7th November - 11:00 PST (Los Angeles) / 13:00 CST (Chicago) / 14:00 EST (New York)</li><li>Broadcast #3: 8th November - 8:30 IST (New Delhi) / 11:00 SGT (Singapore) / 11:00 CST (Shanghai) / 12:00 JST (Tokyo) / 14:00 AEDT (Sydney) / 16:00 NZDT (Auckland)</li></ul>Duration: Approximately 60 minutes<blockquote>Presenter: Vanessa Abercrombie (MFS, GC Applications Chemist, Agilent Technologies)Vanessa Abercrombie is a GC applications chemist at Agilent Technologies in Folsom, California, USA.
