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.
