The Encon Evolution Purge and Trap Concentrator by EST Analytical was designed from the beginning with the user in mind. The system needed to provide high productivity, stability, reliability and fast maintenance to meet the needs of today’s laboratory for the concentration of volatile organic compounds (VOCs). As detection limits have been pushed lower, and Mass Spectrometer systems more sensitive, moisture control is key to the overall stability of the complete system. Other systems collect the analytes and water on the analytical trap, then, during desorb, the sample flows through a moisture removal system on the way to the GC. When evaluating these systems, one problem became quickly apparent. If you are going to remove moisture during the desorption step when your flow is controlled by the GC, the effectiveness of this design will be determined by many different factors.

Features:

Optional sparge heater (patented in Bake mode)
Optional sample foam sensor
Moisture control during purge
8-port valve isolates the moisture control pathway from the desorb pathway
Precise temperature control
Siltek sample pathway

Any issues that occur during warranty should be reported immediately, describing the issues in as much detail as possible. Do not attempt to repair the equipment or involve a 3rd party without our express permission – this will result in voiding our warranty.

We will match our warranty duration with our competitors.

Installation and Training

If you purchase equipment from Spectralab Scientific, we offer installation and familiarization by our service technicians for an additional fee. If the instrument is particularly complicated, we highly recommend this service. If you’ve purchased less-complex equipment from us that you would like to install yourself, we can provide Team Viewer, email, or telephone support for no additional cost.
