HH-Carrier gas purification unit氣體凈化裝置提供了凈化氣相色譜柱進(jìn)氣的方法，有助于降低色譜柱損壞、靈敏度損失和儀器停機(jī)的風(fēng)險(xiǎn)。將氣相色譜氣體過濾器加裝在緊靠儀器進(jìn)樣口的氣體管線中，可以大大降低雜質(zhì)水平，從而改善痕量分析。同時也可以減少進(jìn)入氣相色譜柱的污染物，這對于高溫分析和延長色譜柱壽命而言至關(guān)重要。

　　浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司依據(jù)GB/T 40500-2021噴氣燃料中芳烴總量的測定 氣相色譜法，研制生產(chǎn)，凈化效果好，結(jié)果滿意。

　　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.
