The degradation check I run prior to running samples passes criteria with no problems for both Endrin and DDT. However, after running samples the degradation of DDT is often too high (Endrin is fine). These samples are non-detect for all pesticides, and the only thing suspicious about them is that they are slightly colored.
The degradation problem is fixed after I change out the liner. I'm looking for what could be causing the degradation of DDT so that I can try and fix this issue. Any help/ideas would be greatly appreciated.
