Mon Nov 09, 2: If you are testing drinking water, take a look at EPA Thanks chemwomyn, I am basing my method on that specific EPA method but my retention times are not the same as the ones listed in the method and I am only looking for total THMs, not the full run like the method has developed.


I am using the same column they suggest DB1 but my peaks start 20 minutes after theirs do they start showing on minute 5hence I think my heat ramps do not work well with the compounds at methid settings.
