浩瀚色譜（山東）應用技術開發(fā)有限公司根據(jù)HJ 38—2017《固定污染源廢氣總烴、甲烷和非甲烷總烴的測定氣相色譜法》,結合實際監(jiān)測分析中遇到的問題，對氣相色譜法分析尤其是填充柱法分析時的色譜柱差異、校準曲線制作、總烴峰異常、除烴空氣干擾和采樣容器的選擇等方面進行了探討實驗。實驗結果表明：不銹鋼空柱更適用于總烴的測定；采用一定濃度的標氣、不同的進樣體積來建立校準曲線，校準曲線的相關系數(shù)相對更好；利用真空玻璃瓶采樣，現(xiàn)場操作簡單，易清洗，價格低，適用于采集環(huán)境空氣和無組織排放污染源樣品。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted exploratory experiments on the chromatographic column differences, calibration curve production, total hydrocarbon peak anomalies, hydrocarbon removal air interference, and selection of sampling containers in gas chromatography analysis, especially in packed column analysis, based on HJ 38-2017 "Gas Chromatography Method for the Determination of Total Hydrocarbons, Methane, and Non methane Total Hydrocarbons in Fixed Pollution Source Waste Gas" and in combination with practical monitoring and analysis problems. The experimental results indicate that stainless steel hollow columns are more suitable for the determination of total hydrocarbons; Using a certain concentration of standard gas and different injection volumes to establish a calibration curve, the correlation coefficient of the calibration curve is relatively better; Using vacuum glass bottles for sampling, the on-site operation is simple, easy to clean, and the price is low. It is suitable for collecting samples of environmental air and unorganized emission pollution sources.
