HH-Carrier gas purification unit气体净化装置提供了净化气相色谱柱进气的方法，有助于降低色谱柱损坏、灵敏度损失和仪器停机的风险。将气相色谱气体过滤器加装在紧靠仪器进样口的气体管线中，可以大大降低杂质水平，从而改善痕量分析。同时也可以减少进入气相色谱柱的污染物，这对于高温分析和延长色谱柱寿命而言至关重要。

　　浩瀚色谱（山东）应用技术开发有限公司依据GB/T 40500-2021喷气燃料中芳烃总量的测定 气相色谱法，研制生产，净化效果好，结果满意。

　　HH-Carrier gas purification unit provides a method to purify the gas chromatographic column inlet, which helps to reduce the risk of column damage, sensitivity loss and instrument shutdown. By installing the gas chromatography gas filter in the gas pipeline close to the sample inlet of the instrument, the impurity level can be greatly reduced and the trace analysis can be improved. At the same time, it can also reduce the pollutants entering the gas chromatographic column, which is crucial for high-temperature analysis and extending the life of the chromatographic column.

　　Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. developed and produced the gas chromatography method for the determination of total aromatics in jet fuel according to GB/T 40500-2021, with good purification effect and satisfactory results.
