<p><strong>In many laboratories, researchers rely on </strong><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1759"><strong>Thermo Scientific Compound Discoverer software </strong></a><strong>for untargeted and small molecule research. It excels at digesting raw data, uncovering unknowns, and identifying compounds with speed, flexibility and confidence. But when it comes to regulated environments, compliance and reporting are critical; that’s where </strong><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/76"><strong>Thermo Scientific Chromeleon software</strong></a><strong> comes in.</strong></p><p>&nbsp;</p><p>Historically, moving results between the two meant: numerous manual steps, added time, increased risk of error, and a big gap between discovery research and regulated compliance.</p><p>With <strong>Chromeleon version 7.4 software and Compound Discoverer version 3.5 software </strong>that gap process is more streamlined.</p><h3><strong>How it works</strong></h3><h4><strong>1. Compliant MS data acquisition.</strong></h4><p>Chromeleon software manages all aspects of chromatography and mass spectrometry data acquisition, including:</p><ul><li>Instrument control (for LC, GC, MS, including single quadrupole, triple quadrupole and high-resolution accurate mass)</li><li>Automated sequences and sample preparation</li><li>Compliance-ready audit trails and electronic signatures</li><li>Centralized project and user management</li><li>Secure, traceable data storage ready for downstream processing</li></ul><h4><strong>2. Discovery and identification.</strong></h4><p>Raw data files can be transferred to Compound Discoverer software for advanced discovery and identification using powerful algorithms and a comprehensive suite of spectral libraries (like <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1764"><strong>mzCloud</strong></a>), chemical databases, fragment and neutral loss databases, and in-silico fragmentation prediction.</p><p>When discovery work is complete and finalized, Compound Discoverer software now has the option to export data as a Chromeleon list, giving users the option to export all ion types, base ion with fragments, or base ion with in-source fragments back to Chromeleon software.</p><h4><strong>3. Seamless return to Chromeleon software. &nbsp;</strong></h4><p>Chromeleon 7.4 software introduces an import mechanism that brings Compound Discoverer results directly into the software. Users can import the components within the Chromeleon List directly into the MS Component table of the processing method. This enables you to take the discovery work done in Compound Discoverer software, bring it into Chromeleon software, and generate reports in a fully compliant environment.</p><h3><strong>The benefits</strong></h3><ul><li><strong>Compliance you can trust:</strong> Chromeleon software provides the procedural controls, audit trails, and report generation that regulated labs demand.</li><li><strong>Discovery without compromise:</strong> Researchers can continue to use Compound Discoverer software for flexible data mining and confident compound identification.</li><li><strong>One holistic workflow:</strong> Instead of fragmented manual transfers, labs now have an end-to-end import/export mechanism connecting research and compliance.</li><li><strong>Identity confirmation across platforms:</strong> Evidence of spectra is available in both software, ensuring consistency and confidence in results.</li></ul><h3><strong>From discovery to decision</strong></h3><p>With this new connectivity, you no longer must choose between flexibility for research and rigor for compliance. Instead, you can perform advanced discovery work and seamlessly push results into Chromeleon software to finalize reports, meet procedural compliance, and share data with stakeholders.</p><p>It’s the best of both worlds: <strong>discovery and compliance, integrated.</strong></p><h3><strong>Learn More</strong></h3><p>Have questions or want to learn more? <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/chromatography/chromatography-data-systems-cds/cds-software-built-mass-spectrometry.html">Contact us</a> to learn how this integrated approach can support your analytical goals, or take a look at our <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/76"><strong>Chromelon software</strong></a> and <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1759"><strong>Compound Discoverer software</strong></a> storefronts!</p><blockquote><p><strong>Visit us on&nbsp;</strong><a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/showcase/72003132/admin/dashboard/"><strong><u>LinkedIn:</u></strong></a>&nbsp;#Chromeleon #CompoundDiscoverer #Software</p></blockquote>

Connecting Discovery and Compliance: Compound Discoverer Software Meets Chromeleon CDS

<p><strong>Proficiency testing (PT) is applicable to quantitative, qualitative and interpretative assessments, but this leaflet will concentrate on PTs for quantitative tests. Participation in PT is an essential part of the quality assurance in analytical laboratories and provides them with many benefits. In PT the provider evaluates the performance of participants against pre-established criteria defined in the design of the PT scheme.</strong></p><h4><strong>Performance evaluation&nbsp;</strong></h4><p>The majority of PT schemes involve some form of performance score, such as the <i>z</i> or similar scores<sup>1</sup> , and corresponding assessment criteria. An assigned value (<i>x<sub>pt</sub></i>) and a standard deviation for proficiency assessment (<i>s<sub>pt</sub></i>) are determined and used to calculate the performance score of the laboratory result (<i>x<sub>i</sub></i>), e.g. the <i>z</i> score with <i><strong>z = (x<sub>i</sub> - x<sub>pt</sub> ) / s<sub>pt</sub></strong></i></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_How_can_proficiency_testing_help_my_laboratory_2_c1bf0b596f.jpg" alt="Eurachem: How can proficiency testing help my laboratory?" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_How_can_proficiency_testing_help_my_laboratory_2_c1bf0b596f.jpg 195w," sizes="100vw" width="952" height="761"></p><p>Assessment of <i>z</i> scores is based on the following criteria:&nbsp;</p><ul><li><strong>|</strong><i><strong>z</strong></i><strong>| ≤ 2.0</strong> is regarded as satisfactory;&nbsp;</li><li><strong>2.0 &lt; |</strong><i><strong>z</strong></i><strong>| &lt; 3.0</strong> is regarded as questionable (‘warning signal’);&nbsp;</li><li><strong>|</strong><i><strong>z</strong></i><strong>| ≥ 3.0</strong> is regarded as unsatisfactory (‘action signal’).&nbsp;</li></ul><p>This is based on the concept that normally distributed analytical results lie within <strong>two standard deviations with a probability of ca. 95 %</strong>, and within <strong>three standard deviations with a probability of 99.7 %</strong>.&nbsp;</p><p>PT providers have several options to determine <i>s<sub>pt</sub></i> such as prescribed/perceived desirable analytical performance or the observed distribution of data. The <i>s<sub>pt</sub></i> used by the PT provider may not be appropriate for all laboratories. If justified, the participants may then calculate their own <i>z</i> score using an alternative spt value which is fit for their purpose.&nbsp;</p><h4><strong>Corrective actions</strong></h4><p>Unsatisfactory performance scores (‘<strong>action signal</strong>’) indicate possible problems in the analysis undertaken. The laboratory must investigate this (e.g. by<strong> checking for transcription/calculation errors, trueness and precision</strong>) and, if necessary, address the problems through appropriate corrective actions. Participation in the PT provides very limited benefits to the laboratory, if unsatisfactory performance scores are not acted upon.</p><h4><strong>Evaluation of results over time&nbsp;</strong></h4><p>In addition to internal quality control, regular participation in PT enables laboratories to monitor their performance over time and to identify trends before these become problems. Performance scores obtained from subsequent PT rounds can be plotted in a control chart.&nbsp;</p><h4><strong>Method comparisons&nbsp;</strong></h4><p>Where PT schemes require participants to report details of the method used, the PT report may enable the participant to compare the performance of their method with that of other methods used.&nbsp;</p><h4><strong>Use of PT data to estimate bias&nbsp;</strong></h4><p>The bias of a method should be established using <strong>certified reference materials (CRMs)</strong> or comparison with a <strong>reference method.</strong> However, these may not be available for all matrices, analytes and levels, or CRMs may not be fully representative of the real test samples. Participation in PT provides the opportunity to check the bias taking into account the effects of matrix and concentration variation, provided that a reliable estimate of the “<strong>true value</strong>” is assigned in the PT. Participation in several PT rounds also provides information on the bias variability which can be used as a contribution in the laboratory evaluation of the measurement uncertainty.&nbsp;</p><h4><strong>Use of PT to check measurement uncertainties&nbsp;</strong></h4><p>The ζ (zeta) score can help to check the plausibility of the laboratory’s measurement uncertainty estimate. It is calculated as follows:</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_zeta_score_calculation_b70d8b1187.jpg" alt="Eurachem: Zeta score calculation" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_zeta_score_calculation_b70d8b1187.jpg 245w," sizes="100vw" width="423" height="188"></p><p>where <i>x<sub>i</sub></i> is the laboratory’s result, <i>x<sub>pt</sub></i> the assigned value, and <i>u(x<sub>i</sub>)</i> and <i>u(x<sub>pt</sub>)</i> are their respective standard uncertainties.&nbsp;</p><p>The assessment criteria for satisfactory, questionable and unsatisfactory results are the same as for the <i>z </i>score. The uncertainty reported by a laboratory for its measurement result is an estimate of the accuracy that the laboratory claims to reach. If <i>ζ</i> scores are outside the acceptable range, this shows that the laboratory is not able to fulfill its own requirements. In other words the measurement uncertainty is underestimated.&nbsp;</p><p>Additionally, the standard measurement uncertainty of a laboratory result can be expected to be lower than the reproducibility observed in the proficiency test. If the measurement uncertainty is much lower the uncertainty estimate should be reviewed.&nbsp;</p><h4><strong>Demonstration of competence&nbsp;</strong></h4><p>Successful participation in <strong>PT (| z | ≤ 2.0)</strong> is often seen as a proof of competence to customers, accreditation bodies and regulatory authorities. PT can also provide a valuable educational element to the laboratory, for example it can indicate the success of staff training or where additional training is required.&nbsp;</p><h4><strong>More information / further reading&nbsp;</strong></h4><p>B.
