目标：

•    Develop a reverse phase HPLC method to detect triazine herbicides (propazine, atrazine, ter-butylazine, simazine and irgarol) using a single quadrupole MS detector with field free APCI source
•    Determine the detection limits for 5 triazine herbicides
•    Study the effect of a nitrogen supply hydrocarbon trap on sensitivity determination of 5 triazine herbicides
•    Study the fragmentation pattern of triazine herbicides compounds using APCI and capillary exit collision induced decomposition (CID) in positive ionization mode
