Determination of Propylene Oxide in Hydroxypropyl-β-cyclodextrin by Capillary Gas Chromatography
Determination of Propylene Oxide in Hydroxypropyl-β-Cyclodextrin by Capillary Gas Chromatography Details:

Name: capillary column
Stationary phase: 6% nitrile propylphenyl 94% dimethylpolysiloxane,
Specifications: 30m*0.53mm*0.3um
Model: HH-624
Application: Determination of Residues of Propylene Oxide in Hydroxypropyl β-Cyclodextrin by Gas Chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for the determination of residual propylene oxide in hydroxypropyl-β-cyclodextrin by capillary gas chromatography. Methods: The chromatographic column was HH-624 quartz capillary column, the column temperature was temperature-programmed, the FID detector was used, the detector temperature was 250℃, the injection port temperature was 250℃, and dimethyl sulfoxide was used as the solvent. Results: The linear range of the detection concentration of propylene oxide was 0.1～5.0 mg·ml~(-1)(r=0.999 9); the average recoveries were 99.0%, (RSD was 1.9%,); the lowest detection rate was The limit is 0.81 ng; the residues of propylene oxide in the three batches of samples all meet the requirements of the Chinese Pharmacopoeia. Conclusion: The method is simple, accurate, high sensitivity and good repeatability, which can be used for the determination of propylene oxide residues in the drug.
