Materials were evaluated for potential use as ambient air sample lines for unsymmetrical dimethylhydrazine UDMH and hydrazine. FEP a fluorinated polymer and high density polyethylene tubing materials reached the maximum response levels for TLV and lower concentrations of UDMH. Sample lengths of 23m and 61m were investigated for their effect on performance. Other areas examined were humidity, conditioning the sample tubing, and cleaning agents. High density polyethylene performed the best after ambient air conditioning of the tubing. Keywords Unsymmetrical dimethylhydrazine, Sample transport, Hydrazine, Tubing, Vapor detection.
