## Abstract Calcium is separated as oxalate in a centrifuge tube. The precipitate is estimated by dissolving in a known excess of ceric sulphate, excess of which is then determined absorptiometrically. The range covered is 100โ1000 ฮผg. calcium.
The separation performance and sensitivity of an earlier developed system which uses capillary electrophoresis coupled on-line with a flame photomet-ลฝ . ric detector originally developed for gas chromatography are considerably improved. The liquid junction used in order to decouple the electrical fi
