Abstract
To establish a method for determination the assay of glycerin in Dexamethasone Sodium Phosphate Injection, use GC with column of HP-1, nitrogen as the carrier gas, and FID as the detector, use external standard method to calculate the assay of glycerin. Peak area and concentration presents good linearity in experimental range, the correlation coef icient is 0.999, the average recovery is 97%(n=9),RSD is 0.8%.The method has a good specificity, reproducibility, accurancy and high sensitivity, can use to determination the assay of glycerin in Dexamethasone Sodium Phosphate Injection.关键词
