The EST Evolution is designed to remove water during the purge process As you purge, the water and VOCs travel through the Moisture Reduction Trap (MoRT), preventing the water from contacting the analytical trap, minimizing volume of the desorb pathway, and sharpening chromatographic peak resolution. As you purge, the water and VOCs travel through the Moisture Reduction Trap (MoRT), preventing the water from contacting the analytical trap, minimizing volume of the desorb pathway, and sharpening chromatographic peak resolution With a cooldown time of less than two minutes, cycle time and productivity are optimized. Purge and trap refers to the headspace technique in which volatile organic compounds (VOCs) are purged out of the sample matrix by an inert gas and carried onto a sorbent trap, where they are concentrated and later introduced into an instrument (eg, gas chromatography (GC) or GC/mass spectrometry (MS)) for analysis.

Purge and Trap are time proven How It Works The Stratum PTC purges VOCs from liquids or solids by passing an inert purge gas through your sample matrix The VOCs are extracted and collected onto an analytical trap After purging is complete, the trap is heated and VOCs are released and delivered to a gas chromatograph for separation and detection. Perhaps the most commonly used and most sensitive technique for volatile analysis is purge and trap concentration, also known as dynamic headspace sampling Sample is deposited into the sparging vessel where method analytes are purged from the water using a helium or other inert gas stream to sparge through the sample. The Purge and Trap process involves purging the sample with an inert gas in a sealed environment (sparge vessle) at the appropriate temperature The gas going through the sample will establish thermal equilibrium with VOCs in the sample, therefore transferring the VOCs from an aqueous state to a vapor.

Purge and Trap Operation Overview A measured amount of sample is placed in a sealed vessel The sample is purged with inert gas, causing VOCs to be swept out of the sample The VOCs are retained in an analytical trap, which allows the purge gas to pass through to vent. Purge and Trap is a type of dynamic headspace extraction of VOC compounds where a purge gas, such as helium or nitrogen, is passed through a sample and the VOCs are carried to a trap to concentrate them Used globally for environmental and food testing, Purge and trap can easily perform part per trillion levels of detection using GCMS.
