507 UCMR method: Questions
Posted: Wed Oct 27, 2004 6:09 pm
Hello everybody-
Anyone in here run method EPA 507 for UCMR compounds? molinate, EPTC and terbacil are the analytes. I've actually been having problems with terbacil; it's not visible in the chromatogram, and I've even run a high concentration of it by itself - no visibility either.
I've looked up any information about terbacil degradation online, and couldn't find anything relevant.
Can anyone offer suggestions or tips or anything that might lead me in the right direction?
Thanks
