Analysis of PCBs and Organochlorinated Pesticides in River Water Using Simultaneous Scan/MRM Measurement in GC-MS/MS (1)
PCBs and some chlorinated pesticides are resistant to decomposition in the environment, and tend to accumulate in living organisms. As a result, they are designated as POPs (Persistent Organic Pollutants) under the Stockholm Convention. In monitoring these environmental pollutants in river water and sludge, sensitivity for the detection of trace quantities and separation from impurities in the samples become important issues. In addition, in recent years, incidents of the discharge of chemical substances have increased on a global scale, heightening demands for the identification of unanticipated pollutants in order to investigate causes and take necessary measures swiftly.
The GCMS-TQ8030 GC-MS/MS system achieves simultaneous scan/MRM measurements using high-speed scan and highspeed MRM data acquisition technology.
This Application Data Sheet reports on MRM sensitivity and analytical repeatability when using simultaneous scan/MRM measurements with respect to PCBs and chlorinated pesticides. Application Data Sheet No. 79 presents an example of the quantification of PCBs and chlorinated pesticides by using the MRM data acquired in simultaneous scan/MRM measurements of a river water sample. In addition, Application Data Sheet No. 80 features an example of screening for environmental pollutants not suited to MRM measurement by applying Compound Composer Database Software to the scan data acquired in simultaneous scan/MRM measurements.
