3 Method summary

The remaining hydrazine in the sample was extracted with N,N-dimethylformamide, and the extract was added to a sodium chloride solution, followed by extraction with cyclohexane. Ring The alkane extract was purified by N-propyl ethylenediamine solid phase extraction packing and C18 solid phase extraction packing, and determined by gas chromatography-mass spectrometry. Internal standard method for quantification.
