- Wheaton Purge & Trap System The Wheaton Purge and Trap Apparatus is widely used for the isolation of pollutants in soil, sediment, waste water, and other solid and liquid samples by purging a clean gas over and thru the sample contained therein and trapping the purged volatiles on adsorbent traps.
The Wheaton Purge and Trap Apparatus is widely used for the isolation of pollutants in soil, sediment, waste water, and other solid and liquid samples by purging a clean gas over and thru the sample contained therein and trapping the purged volatiles on adsorbent traps.
When ordering the Short Path Thermal Desorption System, a wide range of systems and accessories are available depending on the application requirements of the user.
After conditioning and sample loading, the ends of the tubes are fitted with stainless steel caps with seals to maintain the integrity of the medium and sample.
The top fitting of both purge heads consists of a 1/16" fitting for the attachment of the sparging needle followed by needle adaptor to seal the needle in place and provide for the attachment of the purging gas line.
Seals are utilized in a variety of locations in the Short Path Thermal Desorption Unit.
This device is used to inject or load liquid samples directly into the S.I.S. Thermal Desorption Tubes, forcing the syringe contents onto the adsorbent resins in the desorption tube without any loss of sample due to back evaporation.
Fittings to connect our 1/4" O.D. GLT desorption tubes to your particular application.
The Extraction Cell system consists of two stainless steel plates which are separated by an inter-changeable PTFE insert.
The Purge and Trap System consists of two single-ball rotameters with adjustable needle valve mounted on a nylon plastic base with an 18" long mounting rod support.
This Sample Collection System permits the purging of volatiles and semi-volatile components present in solid materials and their trapping on Desorption Tubes packed with an adsorbent resin for subsequent analysis by desorption utilizing the Short Path Thermal Desorption System.
