GERSTEL Material Emissions

Upholstery, carpeting, adhesives, sealants, paints, and various building materials can contain and emit volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs), which impact indoor air quality and can contribute to “sick building syndrome” (SBS). SBS is a term used when bad indoor air quality leads to health problems or even illness among occupants. In order to test materials used inside our homes, workplaces, and automobiles their VOC and SVOC emissions are determined using an emission test chamber or automobile interior under controlled conditions. Similar techniques are also used in the Semiconductor/Electronics industry as well for polymers and packaging.

Direct thermal extraction with the GERSTEL Thermal Desorption Systems (TDS) provides the widest range of compound detection and lowest detection limits.

GERSTEL's unique valve-less design and the availability of desorption at high temperature provides for the best determination of high boiling compounds when compared to systems using valves that need to be kept at lower temperatures. The use of the GERSTEL CIS as a cold trap allows the widest range of compounds to be determined in "true-splitless" mode since high flow rates and sample splitting is not required to desorb compounds from the CIS liner. This feature provides the lowest detection limits available.
