The use of a solid sorbent as a collection medium for TNT and RDX vapors

Sampling and sample preparation of environmental material

“…In addition, XAD-7 has been used to sample epichlorohydrin and ethylene chlorohydrin 124) and XAD-4 has been used to collect 5,5,5-tributyl phosphorotrithioate and dibutyl disulfide 125). Tenax GC is widely used in thermal desorption, it has also been used in a number of solvent desorption methods 131,132) and in combination with polyurethane foam for pesticides and semivolatile organic compounds 134).…”

Minimizing thermal degradation in gas chromatographic quantitation of pentaerythritol tetranitrate

“…Other published laboratory methods for analysis of trace explosive vapors such as trinitrotoluene (TNT) and hexamethylenetetramine (RDX) involve collection on sorbent-filled tubes during active sampling [5][6][7][8][9][10]. The analyte is then thermally desorbed and refocused on a cryogenically cooled gas chromatograph (GC) inlet, followed by gas chromatographic analysis.…”

Development and validation of an air monitoring method for 1,3-dichloropropene, trans-1,2,3-trichloropropene, cis-1,2,3-trichloropropene, 1,1,2,3-tetrachloropropene, 2,3,3-trichloro-2-propen-1-ol, and 1,1,2,2,3-pentachloropropane

“…Tenax-GC, a polymer of 2,6-diphenyl-p-phenylene oxide, has been reported to be an effective absorbent for the analysis 0003-2700/84/0356-2134$01.50/0 of a variety of organic compounds (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Tenax has been shown to be efficient in trapping chlorinated hydrocarbons (2, 3, [6][7][8].…”

“…Tenax has been shown to be efficient in trapping chlorinated hydrocarbons (2, 3, [6][7][8]. Solvent desorption of specific compounds from Tenax-GC has also been shown to be a useful technique (4,5). For analysis, electron capture detection has been well documented as a selective and sensitive gas chromatographic detection system in connection with industrial hygiene methodology (12)(13)(14).…”
