Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. analyzed the current situation of the determination method of acetaldehyde in pharmaceutical polyester (PET) bottles, and improved its standards. Methods: The optimized HS-GC method was used to determine the acetaldehyde in pharmaceutical PET bottles. Aldehyde residue. The headspace equilibrium temperature was 40°C, the loop temperature was 50°C, the transfer line temperature was 60°C, the headspace equilibrium time of the reference substance was 30 min, the sample headspace equilibrium time was 8 h, and the injection volume was 1 mL; the column PQ, The column temperature was 130°C, the inlet temperature was 200°C, the detector temperature was 250°C, the carrier gas was nitrogen, the column flow rate was 1.5 mL·min^(-1), and the split ratio was 30:1. Results: The optimized acetaldehyde was used for the determination Method, the injection volume of acetaldehyde reference substance showed a good linear relationship in the range of 0.2~3.0 μg, r=0.9996; the high, medium and low sample recovery rates were 98.6%, 106.3% and 100.4%, respectively. Determination of acetaldehyde before and after optimization There was no significant difference in the results of the acetaldehyde content measured by the method. Conclusion: The optimized and improved acetaldehyde determination method can quickly and accurately determine the acetaldehyde content in pharmaceutical PET bottles. The quality control of PET bottles provides guidance.
