Perchlorate salts are relatively stable, soluble in water, and migrate into groundwater sources causing possible challenges for drinking water suppliers as dissolved perchlorate has been identified to impair normal thyroid function. The development of a sensitive analytical method for perchlorate determination is therefore important to protect public health. This article addresses the validation of ion chromatography with suppressed conductivity detection (IC–CD), applying isocratic elution to analyze perchlorate.
