Determination of Water in Hydrazine By Gas Chromatography

The gas chromatographic separation of water and hydrazine has been accomplished on a column of Fluoropak-80 coated with 20% Ucon Oil 550X. This separation was applied to the determination of small quantities of water in hydrazine. An automatic integrator was used to make the analysis rapid and reproducible. This analytical scheme is simple and accurate for concentrations of water in hydrazine, ranging from 0.5 to 2.0 wt. %.
