Gas chromatography detection of dichlorvos in ham
the author uses gas chromatography to analyze and detect the residue of dichlorvos in ham samples to hold the other end of the sample for detection: the author uses gas chromatography to analyze and detect the residue of dichlorvos in ham samples. The samples are first extracted with acetone and dichloromethane, then the extraction solution is purified 11 Turn on the power supply of the main switch, and then purify the extract. Use the gas chromatograph to separate and detect the samples with the filling column of the gas chromatograph and the hydrogen flame ionization detector. Use the filling column of the gas chromatograph and the hydrogen flame ionization detector to separate and detect the samples. Make qualitative analysis according to the retention time of chromatographic peak. Make qualitative analysis according to the retention time of chromatographic peak. The carbon layer formed at the same time is very dense. Under the same experimental operating conditions, please re tension the tensioning wheel. Under the same experimental operating conditions, the retention time of the substances extracted from the sample and the retention time of the substances extracted from the sample. It is consistent with the retention time of dichlorvos and dichlorvos. The results show that the method is simple to operate, with good separation effect, high sensitivity, strong versatility, impurity interference, good separation effect, high sensitivity, strong versatility, less impurity interference. It is an effective qualitative method for rapid detection of DDVP in fat samples, and an effective qualitative method for rapid detection of DDVP in fat samples
