Anions per EPA 300.0 and 300.1 Part A using automated dilution


The Environmental Protection Agency (EPA) establishes the maximum contaminant levels (MCL) of various components including anions in water. Growing contaminant lists and stringent regulatory requirements require laboratories to
process more samples in less time without sacrificing accuracy and compliance. Use of ion chromatography (IC) coupled with automated sample preparation such as intelligent dilution and in-line ultrafiltration simplifies analysis, generates more accurate results, reduces analysis time and cost while maintaining compliance and traceability. Anion separation was followed by sequential suppression.
