問題的提出 色譜柱是氣相色譜分析的心臟部分,好的柱子使分析得心應手,不好的柱子往往使分析歸咎失敗。2％QF-1、1.5％OV-17柱是目前公認用來分析有機氯農(nóng)藥殘留量的理想柱子,人們大多認真地照此配柱,裝柱,但對柱的老化問題考慮得尚少。
浩瀚色譜（山東）應用技術開發(fā)有限公司，研制QF-1色譜柱測定有機磷農(nóng)殘，柱效高，分離好，結果滿意。
The chromatographic column is the heart of gas chromatography analysis. Good columns make analysis easy, while bad columns often cause analysis failure. The 2% QF-1 and 1.5% OV-17 columns are currently recognized as ideal columns for the analysis of organochlorine pesticide residues. Most people carefully follow this method to prepare and install columns, but little consideration has been given to the aging of the columns.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a QF-1 chromatographic column for the determination of organophosphorus pesticide residues, with high column efficiency, good separation, and satisfactory results.
