Greetings all,

This is my first post on this forum - I'm glad to be here, and hope to contribute to help solve others' problems (and not just ask questions to serve my own needs)...

Just wondering if anyone out there has any tricks for cleaning up extracts for method 8141 (organophosphorus pesticides). It's a tricky analysis to do cleanup on, due to the ease with which you can nuke your targets. We've recently had a couple of dirty samples do a serious number on our naled response, causing several days worth of instrument maintenance and tinkering.

Thanx for any ideas.
