This work investigates an automated technique for rapid detecting the glucose content in glucose injection by reaction headspace gas chromatography (HS-GC). This method is based on the oxidation reaction of glucose in glucose injection with potassium dichromate. The carbon dioxide (CO₂) formed from the oxidation reaction can be quantitatively detected by GC. The results show that the relative standard deviation (RSD) of the present method was within 2.91%, and the measured glucose contents in glucose injection closely match those quantified by the reference method (relative differences <6.45%). The new HS-GC technique is rapid, practical and can be used to the batch detection of the glucose content in glucose injection related applications.

这项工作研究了一种自动技术，该技术可通过反应顶空气相色谱法（HS-GC）快速检测葡萄糖注射液中的葡萄糖含量。该方法基于葡萄糖注射液中葡萄糖与重铬酸钾的氧化反应。由氧化反应形成的二氧化碳（CO ₂）可以通过GC定量检测。结果表明，本方法的相对标准偏差（RSD）在2.91％以内，并且葡萄糖注射液中测得的葡萄糖含量与参考方法所定量的葡萄糖含量非常匹配（相对差异<6.45％）。新的HS-GC技术快速，实用，可用于在葡萄糖注射相关应用中批量检测葡萄糖含量。
