Many types of pesticides are applied to keep golf courses green. While less pesticide is used on golf courses than on agricultural land, the proximity of Japanese golf courses to water sources has resulted in the regulation of some pesticides due to concerns of pesticide contamination of river and drinking water.
This data sheet illustrates an example of LC-MS analysis of pesticides prescribed for LC analysis under the official regulation, with the mobile phase solvent changed to a buffered ammonium acetate solution. As the final pretreatment solvent is acetonitrile, analysis was conducted with a semi-micro column using a maximum injection volume of 5J1L.
Fig.1shows the mass chromatogram made in scan mode, and Fig.2 shows the mass spectra of asulam, thiram and pencycuron.
