Cyclohexane is a chemical raw material. Cyclohexane is usually determined by the external standard method of gas chromatography. The disadvantage of the external standard method is that the effect of cyclohexyl hydrogen peroxide has not been eliminated, and the error caused by the injection is very large. Although the area normalization method can eliminate the injection error, due to the large cyclohexane content in the sample and the short retention time, Affects the accuracy of the normalization method, and does not take into account the effect of cyclohexyl hydrogen peroxide in the sample on the chromatographic decomposition.
Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. keeps pace with the times and develops a special packed column to measure the trace moisture in industrial cyclohexane. The results show that under the condition of the injection volume of 2 μL, the trace moisture in cyclohexane is increased. The standard recovery is 98.46% ~ 101.92%, and the relative standard deviation is 0.15% ~ 0.35%. This method has the advantages of fast analysis speed, high sensitivity, simple operation and so on.
