I am having some problems with the recovery step.
OK. What procedure are you using for extracting the OPs from the samples? Given your question, you should have radically different recoveries given that you've covered a range of the most difficult sample matrices that exist.
We use the attached method.
It is very important to do method validation method for organo phosphorus pesticides detection , and then make sure recovery between (75-120)%.
There are many organo phosphorus pesticides affected acidity and base , so the know what kinds that are detected.
If you use LC MSMS , what kind mobile phase, used column.
