Gas chromatograph for the determination of acetaldehyde in medicinal polyester bottles
Gas chromatograph for the determination of acetaldehyde in pharmaceutical polyester bottles Details:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. analyzed the current status of acetaldehyde determination methods in pharmaceutical polyester (PET) bottles, and improved its standards. Methods: The optimized HS-GC method was used to determine the acetaldehyde residues in pharmaceutical PET bottles. 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; ×0.320 mm×0.25 μm), the column temperature was 50 °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: Using the optimized acetaldehyde determination method, the injection amount of acetaldehyde reference substance showed a good linear relatio
