Struggling to accurately measure semi-volatile analytes? Stricter temperature control with HPLC-CAD analysis just might be the solution you need.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_How_to_Get_More_Accurate_HPLC_Quantitation_of_Semi_Volatiles_1_f2eefd5901.jpeg" alt="Thermo Fisher Scientific How to Get More Accurate HPLC Quantitation of Semi-Volatiles" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_How_to_Get_More_Accurate_HPLC_Quantitation_of_Semi_Volatiles_1_f2eefd5901.jpeg 245w," sizes="100vw" width="1024" height="512">The charged aerosol detector (CAD) is cited as one of the most capable near-universal HPLC detectors available because the response is solely based on particle charge and fully independent of chemical structure.One caveat to know is your mobile phase components must be less volatile than the analytes in solution for detection by the CAD. And while all non-volatiles give a similar uniform response, <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/chromatography/chromatography-learning-center/liquid-chromatography-information/hplc-system-components/how-hplc-detectors-work/charged-aerosol-detection/charged-aerosol-detection-cad-performance-tips.html">the response of semi-volatiles</a> depends on volatility and consequently is less predictable.So, the question then becomes is there a way to address this performance difference and make semi-volatile detection more predictable? One approach for charged semi-volatile analytes is to add a volatile ion-pairing agent of the opposite charge in the mobile phase to force non-volatile behavior.However, this method is analyte specific and may also react with impurities in your mobile phase, leading to higher noise and poorer signal-to-noise (S/N) ratio. What’s really needed is a more global approach to improve the accuracy for measuring semi-volatiles.This approach is now achievable with Temperature Coupling Mode (TCM) in the <a target="_blank" rel="noopener noreferrer" href="https://discover-pharma.com/thermo-fisher-upgrades-charged-aerosol-detection-tech-to-improve-complex-drug-analysis/">Thermo Scientific Vanquish CAD P Series</a>.<h3>Why stricter temperature control matters for measuring semi-volatiles</h3>Before we get into the specifics, you need to understand why temperature control in the CAD is critical to quantitative accuracy, especially for semi-volatiles (Figure 1).<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_How_to_Get_More_Accurate_HPLC_Quantitation_of_Semi_Volatiles_2_e33cff4cac.jpeg" alt="Thermo Fisher Scientific: How to Get More Accurate HPLC Quantitation of Semi-Volatiles: Figure 1.

This fixed temperature difference between the EvapT and CDM could negatively impact the measurement of semi-volatile compounds that require a lower EvapT.Adding TCM resolves this issue, by linking the EvapT and CDM temperatures, thereby improving the quantitation of semi-volatile species.<h3>Using TCM to help improve quantification of semi-volatiles, like fatty acids</h3>To demonstrate the effectiveness of this new temperature coupling feature, we anlazyed a working solution of four individual fatty acids (FAs) and compared the CAD repsonse with TCM turned on and turned off (Figure 2).<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_How_to_Get_More_Accurate_HPLC_Quantitation_of_Semi_Volatiles_3_da6cf5006c.jpeg" alt="Thermo Fisher Scientific: How to Get More Accurate HPLC Quantitation of Semi-Volatiles: Figure 2.

<h3>Introduction</h3>Modern analytical laboratories often operate multiple chromatographic instruments simultaneously, which places high demands on software usability and workspace navigation. <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/999">Clarity Chromatography Software</a> developed by DataApex provides a structured, instrument-oriented user interface designed to simplify work even in complex multi-instrument environments. This article explains how to efficiently move between windows in Clarity.<h3>Concept of Instrument-Centric Workspace Organization</h3><h4>Instrument-Specific Color Schemes</h4>Each instrument in Clarity is visually distinguished by its own color scheme. This design choice allows users to:<ul><li>Instantly recognize which windows belong to the same instrument</li><li>Avoid confusion when multiple instruments are open simultaneously</li><li>Maintain orientation within complex analytical workflows</li></ul>Color coding is consistent across all windows associated with a given instrument.<h3>Types of Windows in Clarity</h3>Within a single instrument context, Clarity typically provides access to several interconnected windows, including:<ul><li>Instrument Window – the central control and overview window</li><li>Chromatogram Window – displays acquired chromatographic data</li><li>Sequence Window – manages sample sequences and runs</li></ul>Efficient navigation between these windows is essential for smooth operation.<h3>Navigation Methods Between Windows</h3>Clarity offers multiple complementary ways to switch between related windows. Users can choose the method that best fits their workflow preferences.<h4>1. Instrument Window Tiles</h4>Within the Instrument Window, large tiles represent related windows.Example workflow:<ul><li>Select the large chromatogram tile to switch directly from the Instrument Window to the Chromatogram Window</li></ul>This tile-based approach is intuitive and visually guided.<h4>2. Toolbar Icons</h4>Each instrument window contains a toolbar with window icons that provide direct access to other related windows.Key characteristics:<ul><li>The same set of window icons is available across all instrument-related windows</li><li>Enables quick transitions, for example:<ul><li>From Chromatogram Window → Sequence Window</li></ul></li><li>Ideal for experienced users who prefer icon-based navigation</li></ul><h4>3. Window Menu</h4>For users who prefer menu-driven control, Clarity includes a Window menu.Typical use case:<ul><li>Select Main from the Window menu to return to the Clarity main window</li></ul>This method is particularly useful when:<ul><li>Navigating back to the global workspace</li><li>Managing multiple instruments at once</li></ul><h3>Practical Navigation Workflow Example</h3>A typical navigation sequence demonstrated in the video follows this logic:<ol><li>Start in the Instrument Window</li><li>Click the Chromatogram tile to open chromatographic data</li><li>Use the toolbar icon to switch to the Sequence Window</li><li>Open the Window menu and select Main to return to the Clarity main interface</li></ol>This combination of tiles, icons, and menus ensures flexible and efficient workspace control.<h3>Advantages of Clarity’s Navigation Design</h3>The navigation system in Clarity provides several practical benefits:<ul><li>Consistency – identical navigation tools across instrument windows</li><li>Efficiency – rapid switching without losing context</li><li>Scalability – effective even with many instruments open</li><li>User preference flexibility – toolbar or menu-based workflows</li></ul>These features are especially valuable in high-throughput laboratories and 24/7 operational environments.<h3>Conclusion</h3>Clarity Chromatography Software uses a well-structured, instrument-oriented window system that simplifies navigation even in complex multi-instrument setups. By combining color-coded instruments, tile-based access, universal toolbar icons, and traditional menus, Clarity allows users to move quickly and confidently between windows.Mastering these navigation techniques significantly improves workflow efficiency, reduces errors, and enhances overall user experience—making Clarity a robust platform for modern chromatographic laboratories.For additional tutorials and practical demonstrations, users are encouraged to explore further educational resources provided by DataApex.
