Determination of 1,1- dimethylhydrazine and products of its
decomposition by ion-pair chromatography
Abstract
The influence of ion- pair reagent (IPR) nature
(sodium octylsulfate, octylsulfonate and sodium dodecylsulfate) on separation
of asymmetric dimethylhydrazine (ADMH) and products of its decomposition using
the column Synergi Hydro RP has been investigated. It is shown that the
application of sodium octylsulfate as IPR is preferable. The approach for
simultaneous determination of hydrazine, methylhydrazine, UDMH, N- nitrosodimethylamine
and tetramethyl-2-tetrazene with limits of detection in water samples 0.3, 0.7, 0.8, 7, and 1.2 ppb, resp. (sample volume 100 µl) has been
proposed.
