Automated, simultaneous microdetermination of calcium and magnesium by atomic absorption.

چکیده
A procedure is described for the simultaneous, automatic determination of serum calcium and magnesium with the AutoAnalyzer, and a dualchannel, double-beam atomic absorption spectrophotometer, the IL Model 153. Advantages over existing procedures include a high rate of analysis (90 samples or 180tests per hour) and low sample consumption (a total of 30 l for both determinations). We have compared the new procedure with a manual one in which the Perkin-Elmer Model 303 atomic absorption spectrophotometer is used.

We describe an integrated automated system for the atomic absorption spectrophotometer. The system makes use of a light-dependent resistor to detect the presence of a marker ion which is present along with the sample ion in the flame. An electronic circuit has been developed which enables the marker ion to trigger the read signal of the spectrophotometer. The system has been tested by determini...
