Trace analysis of haloacetic acids, dalapon, and bromate in drinking water [Technical Document]
Ion chromatography
Trace analysis of carcinogenic substances such as haloacetic acids (HAA), dalapon, and bromate using ion chromatography.
We conducted the analysis by connecting the Metrohm ion chromatography (IC) to an Agilent triple quadrupole mass spectrometer (MS). This high-sensitivity method does not require sample extraction and can eliminate interferences from the eluent due to the Metrohm suppressor module. The matrix spike recovery rate for all target analytes at 1 μg/L was between 65% and 115%, and good results were obtained even with highly contaminated water samples.

basic information
The U.S. Environmental Protection Agency (EPA) and the EU have set the maximum allowable contaminant level for the total concentration of five haloacetic acids (HAA5: monochloroacetic acid (MCAA), monobromoacetic acid (MBAA), dichloroacetic acid (DCAA), dibromoacetic acid (DBAA), trichloroacetic acid (TCAA)) at 60 ppb (60 μg/L). EPA Method 557 describes a method for quantifying these compounds at the μg/L level in various types of water.
