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. :x

I've looked up any information about terbacil degradation online, and couldn't find anything relevant. :shock: Can anyone offer suggestions or tips or anything that might lead me in the right direction?

Thanks
