Lumex Instruments introduces a capillary electrophoresis method for determination of inorganic anions according to EPA 6500 and ASTM D6508-10 test methods

Lumex Instruments introduces a capillary electrophoresis method for determination of inorganic anions; fluoride, bromide, chloride, nitrite, nitrate, ortho-phosphate, and sulfate in drinking water, wastewater and ground water according to EPA 6500 and ASTM D6508-10 test methods.

This test method is applicable for determination of the dissolved inorganic anions; fluoride, bromide, chloride, nitrite, nitrate, ortho-phosphate, and sulfate in aqueous matrices using capillary ion electrophoresis with indirect UV detection. The method can be applied to drinking water, wastewater and ground water according to EPA 6500 and ASTM D6508-10 test methods.

The capillary electrophoresis method for determination of inorganic anions’ concentrations is based on differential migration and separation of anions in the electric field due to different electrophoretic mobility.

Identification and quantitative determination of the analyzed anions are performed using indirect detection by measuring the UV absorption.
