Description:
Two Perkin-Elmer Sequential Tube Samplers (Model STS-25) were evaluated for their performance, portability, and convenience of operation. esults obtained from both samplers and from a collocated Summa-polished stainless steel canister were compared for seven 3-h periods at three sites. pecial attention was given to the monitoring of carbonyl sulfide and carbon disulfide. he samplers were loaded with three sampling tubes, each one packed with 70 mg of Carboxen 1000 (60/80 mesh) and 160 mg of Carbotrap graphitized carbon black (20/40 mesh). n identical tube was used as a field blank. ach tube collected 1200 cm3 of ambient air (20 cmi/min for 60 min) At the end of each sampling period, tubes were sealed and stored in a capped glass tube to prevent contamination and for transportation to a mobile laboratory for analysis. dvantages for the use of the STS-25 are low cost, portability, ease of use, and a design suitable for obtaining sub-part-per-billion detection limits with a standard analytical finish. isadvantages are that it is a "one-short" technique and no universal solid adsorbent material exists.
