Smith, D. CLOSED CYCLE COOLER FOR VOC PRECONCENTRATION. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-93/229 (NTIS PB94130390), 1993.

Description:

The objective of this study was to evaluate a reduced-temperature preconcentrator to replace pr reduce liquid cryogen use in field applications of automated gas chromatographs. he cooler was to be evaluated as a refocusing unit downstream of a solid sorbent trap. losed cycle cooler from Cryoworks (formerly Carlisle Cryotronics) in Carlisle, MA was selected for the evaluation. asic properties of the cooler were evaluated, including cool-down time and heating time. odifications wars made to improve the performance of the unit during the tenting period. etails of the study are presented.
