Development of Air-Monitoring Techniques Using Solid Sorbents.
Los Alamos Scientific Laboratory of the University of California, Los Alamos, New Mexico, 1976 Sep:22 pages
A sampling tube of sufficient capacity for eight hour monitoring of hydrazines or amines has been designed based on the development of air monitoring techniques using solid sorbents. The monitoring methods involve collecting vapors on silica gel or sulfuric-acid coated silica gel in a tube through which air is drawn. Vapor retention has been studied on the latter sorbent for 1,1- dimethylhydrazine (57147), morpholine (110918), and cyclohexylamine (108918). Removal of the sample from the sorbent by elution with dilute acid or water has been measured for hydrazines and aliphatic amines. Analyses of amines and of hydrazine reaction products of 2- furaldehyde have been performed by gas chromatography.
