Purge and Trap is the most effective method for extracting and concentrating volatile organic compounds (VOC) from liquids and solids for analysis via gas chromatography (GC) or GC/MS. The Purge and Trap process involves purging the sample with an inert gas at the appropriate temperature. This transfers the VOCs from an aqueous state to a vapor. The gas is then swept to an analytical trap that absorbs and retains the VOCs, where they are transferred to the Gas Chromatograph for further analysis.

Stay EPA Purge and Trap method compliant with our time tested, global leading instruments. EST analytical instruments are designed with YOU in mind. Can you benefit from increased sample throughput, instrument reliability, and optimized sample prep for purge and trap samples? Maximize productivity and profitability with your new Purge and Trap system.

GC and GC-MS Headspace and SPME

Precise and reproducible sample preperation and sample introduction are what today's lab require when achieving the highest quality GC and GC-MS results when using liquid injection, headspace and SPME methods.

EST analytical has built a reputation for manufacturing high quality rugged XYZ robotic platforms.

Unleash the full power of a rail GC GC/MS Autosampler that was designed with you in mind. The Flex GC GC/MS Autosampler and its design was based on significant market research that asked analysts what current products on the market were lacking and what they would like to see in a new product. That insight resulted in the first US manufactured rail GC GC/MS Autosampler, the FLEX.

Whether your laboratory is responsible for determining compounds in food, beverages or analyzing flavors or odors there’s now a new option.
