Effect of Split Ratio in Determination of OCPs in Traditional Chinese Medicines Using Gas Chromatography
In this work, the effect of split ratio and the column flow in determination of OCPs in Traditional Chinese medicines are discussed in the name of heptachlor. When the split ratio is 60:1, the measured concentration is close to the actual concentration; on the contrary, they lead the measured concentration lower than the actual concentration. The column flow has not obviously effect on result. The split ratio is considered in OCPs analysis.
