Magnesium( II) and calcium( II) in hard water are separated by ion chromatography and detected spectrophotometrically after a post-column reaction with arsenazo-I at pH 10. No sample dilution or pretreatment is needed, and the separation is complete in 3 min. Linear calibration plots are obtained in
## Abstract We have developed a new method to quantitatively determine ionized calcium and total calcium by using high performance capillary electrophoresis (HPCE) with indirect photometric detection. Other cations such as Na^+^, K^+^, and Mg^+^ can also be quantitatively determined. A 70 cm ร 50 ฮผ
