Profile: Xonteck Inc. manufactures ambient air samplers for the environmental industry. The model 910A sampler is designed to collect volatile organic compounds in ambient air. This method is based on collection of whole air samples into a 6-liter summa electropolished canister as outlined in USEPA T0-14/15 method. This sampler is used for pressurized sampling up to 30 psi. A flow controller is utilized to maintain a constant flow over the desired sampling period. A pulse latching solenoid valve is used to avoid the typical temperature rise that would occur with a conventional, normally closed solenoid valve. The temperature rise in the valve could cause out-gassing of organic compounds from the valve seat material. The sampler can be coupled with the model 912 which allows sequenced sampling into 16 canisters. X-can (SUMMA canister equivalent) is used to collect an instantaneous air sample for collection, storage, and analysis of volatile organic compounds (VOCs) using treated air sampling canisters. The canisters are the important part of the whole air VOC analysis.
