氣相色譜外標定量法分析異丙硫醇
氣相色譜外標定量法分析異丙硫醇 詳細信息：


名稱：毛細管柱
規(guī)格：30m*0.25mm*0.25um
型號：HH-5

浩瀚色譜（山東）應用技術開發(fā)有限公司利用GC7990型氣相色譜儀分析了化學合成的異丙硫醇含量.結果表明:在柱溫50℃、汽化室溫度150℃、檢測器溫度150℃、載氣流速1.4 mL/min、分流比50∶1、進樣量2 μL的條件下,色譜分離效果好.以峰面積外標法定量,測得精密度實驗的標準偏差為7.12×10-4,回收率在98.75%～101.25%之間.外標法不需要校正因子,準確性較高,操作簡單,適用于大批量試樣的快速分析.

Analysis of Isopropyl Mercaptan by Gas Chromatography External Standard Quantitative Method
Gas Chromatography External Standard Quantitative Analysis of Isopropyl Mercaptan Details:


Name: Capillary Column
Specification: 30m*0.25mm*0.25um
Model: HH-5

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used GC7990 gas chromatograph to analyze the content of chemically synthesized isopropyl mercaptan. The results showed that the column temperature was 50℃, the vaporization chamber temperature was 150℃, the detector temperature was 150℃, and the carrier gas flow With a speed of 1.4 mL/min, a split ratio of 50:1, and an injection volume of 2 μL, the chromatographic separation effect is good. The peak area external standard method is used to quantify, and the standard deviation of the measured precision experiment is 7.12×10-4. The rate is between 98.75% and 101.25%. The external standard method does not require correction factors, has high accuracy and simple operation, and is suitable for rapid analysis of large quantities of samples.
