藥用聚酯瓶中乙醛測定氣相色譜儀
藥用聚酯瓶中乙醛測定氣相色譜儀 詳細信息：
浩瀚色譜（山東）應用技術開發有限公司分析藥用聚酯（PET）瓶中乙醛測定法現狀,并對其進行標準提高。方法:采用優化后的HS-GC法測定藥用PET瓶中乙醛殘留量。頂空平衡溫度40℃,定量環溫度50℃,傳輸線溫度60℃,對照品頂空平衡時間30 min,樣品頂空平衡時間8 h,進樣體積1 m L;色譜柱HH-Wax（30 m×0.320 mm×0.25μm）,柱溫50℃,進樣口溫度200℃,檢測器溫度250℃,載氣氮氣,柱流量1.5 m L·min-1,分流比30∶1。結果:采用優化后的乙醛測定方法,乙醛對照品進樣量在0.2～3.0μg范圍內呈良好線性關系,r=0.999 6;高、中、低加樣回收率分別為98.6%、106.3%和100.4%。優化前后乙醛測定法測得乙醛含量結果無顯著性差異。結論:優化提高后的乙醛測定法能快速、準確地測定藥用PET瓶中乙醛含量,該研究為乙醛測定法的標準提高以及藥用PET瓶的質量控制提供指導意義。

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
