Great Internal Standards for Pesticide Residues...SRMs too!19 Feb 2015
In just about all of my pesticide residue work, I use a convenient multicomponent internal standard mix that contains several PCBs as well as popular internal standard compound triphenylphosphate. The mix contains the six compounds in the chromatogram below. I have been working on a method for our GC Multiresidue Pesticides Kit which has about 200 compounds. We will be publishing the method...retention times and SRMs soon!
I am just about to put the kit into action with some citrus and celery samples. Luckily, I realized I had forgotten to add my internal standards to my method.
I hope this helps shortcut your own method development.
