Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used PEG-20000 capillary chromatographic column to establish the best separation conditions for the components in N, N-dimethylformamide (DMF) products, and used gas chromatography-mass spectrometry and reference material control to qualitatively determine the components of the products. Through experiment and theoretical calculation, the relative quality correction factor of each component was established, and the correction area normalization method for determining the purity and impurity content of DMF was established. The method has good accuracy, precision and repeatability, and is a fast and reliable quantitative analysis method.
