NMRS Determination of Equivalent Water Content in Nitrogen Tetroxide

Equivalent water content in nitrogen tetroxide was determined by NMRS using deuteroacetonitrile as internal standard.A self-made double-site glove box was used for pretreatment of the sample.Linearity range of the method was kept over 0.004 0%-0.390 3%.Detection limit (3S/N) of 1×10-4% was found.Relative deviation between the results found by the NMRS method and those found by GC were all ≤3.8%.
