Perchlorate Detection by IC Using Hydroxide as the Eluent
Summary
Perchlorate in water has become a growing concern due to its widespread use in industrial products and its potential impact on human health, particularly thyroid function.
This application note presents an ion chromatography method using hydroxide as the eluent to determine perchlorate in water according to EPA 314.0.
The method achieves a reporting limit down to 1 ppb and maintains strong peak shape and accuracy even in samples with high total dissolved solids, using automated eluent generation and conductivity detection.
Validation results show reliable performance with accurate spike recoveries and minimal interference from other common anions such as chloride, carbonate, and sulfate.
