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.
All tubes are constructed from borosilicate glass with 0.5" O.D. tube ends for mating with standard 1/2" fittings.
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.
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.
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.
