Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has improved the current method for the determination of acetaldehyde in the quality standard of polyester bottles for oral use. Methods: The content of acetaldehyde was determined by headspace gas chromatography. RESULTS: The acetaldehyde injection amount was linear in the range of 0.2-3.0 μg, r=0.995 4, the average recovery was 103.2%, and the RSD=3.5% (n=9). Conclusion: The revised method is simple and accurate, and can more effectively control the quality of oral medicinal PET bottles.
