Analysis of HAA5 in drinking water with a LOD of 6 ng/ml accroding to european/german law. Trichloroacetic acids has very different optimzed iFunnel values than the other haloacetic acids, which make it hard to combine all in one method. Does anyone have a single method for all 5 HAAs? I´m working with 0,05 formic acid and 0,5 mmol/l NH4F (A) and methanol (B). The injection volume is 25 µl.
All advices are welcome.
