Determination of 1,1-dimethylhydrazine and its decomposition products using ion-pair chromatography

The influence of the nature of the ion-pair reagent (IPR) using sodium octylsulfate, octylsulfonate, and dodecylsulfate as an example on the separation of asymmetric dimethylhydrazine (ADMH) and its decomposition products has been investigated using a Synergi Hydro RP column. It has been shown that the use of sodium octylsulfate as an IRP is preferable. The approach to simultaneous determination of hydrazine, methylhydrazine, ADMH, N-nitrosodimethylamine, and tetramethyl-2-tetrazene with detection limits in water matrices of 0.3, 0.7, 0.8, 7, and 1.2 μg/L respectively (sample volume of 100 μL) has been proposed.
