چکیده

A semiautomatic procedure for the direct estimation of both serum calcium and magnesium is described. The indicator used, Eriochrome blue SE (EBSE), has the advantage of stability and freedom from interference by naturally occurring substances. The procedure requires 3-5 mm. per sample and is very reproducible. The values obtained agree with those obtained by back-titration of excesschelator and are consistently 0.3 mg./100 ml. less than those obtained by a standard oxalate precipitation method.

A simple and rapid method for the simulataneous determination of calcium and magnesium from the same sample of blood serum.

A simple and rapid procedure has been developed for the complexometric titration of serum calcium and magnesium using "plasmocorinth B" as indicator. Both determinations can be carried out from the same 0.5 ml. sample. The method is in good agreement with the established calcium and magnesium methods.

A micro-method for serum calcium and serum magnesium.

A simple, rapid, accurate method for determining calcium and magnesium separately in 0.1 ml. volumes of serum (or heparinized plasma) was required for the routine chemical pathology service of a children's hospital (Wilkinson, 1955-6). The apparatus used had to be generally available, the minimum of pipetting and transfer was desirable for the sake of accuracy, and the method had to be specific...

The determination of metals in blood serum by atomic absorption spectroscopy-II Magnesium

The magnesium content of blood serum may be accurately determined by atomic absorption measurements. Analysis can be carried out on as little as 0.05 ml of serum and the only preliminary treatment necessary is dilution of the sample with water containing about 1 per cent of ethylenediaminetetracetic acid or of strontium chloride. Existing methods for estimation of magnesium THE lack of detailed...
