| titleOfInvention | Detection method and application of polyol |
| abstract | The invention discloses a method for detecting polyhydric alcohol, which comprises the following steps: preparing a test sample into a test sample solution by using a diluent, and detecting the test sample solution by using a gas chromatography, wherein the chromatographic conditions are as follows: the stationary phase is a capillary chromatographic column of polyethylene glycol, the temperature of a sample inlet is 200-fold-used 250 ℃, the temperature of a detector is 220-fold-used 350 ℃, the column temperature is detected according to the temperature program, and the specific temperature program is as follows: the initial temperature is 110-; the polyhydric alcohol is at least one of diethylene glycol, dipropylene glycol and tripropylene glycol. The method is simple to operate, good in separation degree, sensitive and efficient; diethylene glycol, dipropylene glycol and tripropylene glycol can be detected. The method can be applied to the detection of the polyhydric alcohol in the ornidazole injection, and provides a reliable analysis method for the quality control analysis of the ornidazole injection. |
