Autosamplers - Purge/Trap

Purge and trap autosamplers streamline sample preparation for gas chromatography (GC) and GC/mass spectrometry (GC/MS) analysis by automating the volatile organic compound (VOC) extraction process. These sophisticated instruments efficiently extract and concentrate VOCs from liquid or solid samples by purging them with an inert gas, trapping the volatiles on an adsorbent trap, and then thermally desorbing them onto the GC column. This technique improves analytical sensitivity and accuracy, especially for trace-level analysis. Purge and trap autosamplers from leading manufacturers like Tekmar, OI Analytical, and Gerstel seamlessly integrate with most major GC and GC/MS systems from brands such as Agilent, Thermo Fisher Scientific, and Shimadzu, optimizing workflows for environmental monitoring, food and beverage analysis, and forensic... + More

Purge and trap autosampler technology is crucial for various scientific techniques, including environmental analysis of water and soil samples for pollutants, determining volatile flavor and aroma compounds in food and beverages, and analyzing blood alcohol content in forensic toxicology. These autosamplers provide consistent and reliable sample introduction, minimizing human error and improving data reproducibility. The automation capabilities of these instruments increase sample throughput and free up valuable laboratory time, making them an essential tool for laboratories conducting routine VOC analysis and demanding research applications. Automated features such as sample vial handling, inert gas purging, and trap heating enhance overall laboratory efficiency and ensure accurate and reproducible results. - Less
