چکیده

Modification of a Perkin-Elmer 603 atomic absorption spectrophotometer by adding a high-intensity tungsten-halogen lamp for background correction significantly improved the detection limit for elements that have analytical wavelengths in the near-ultraviolet and visible regions. Chromium in human serum and urine can be measured, with a simplified sample-handling technique, in concentrations of less than 0.1 microgram/liter. For comparison, the mean value for chromium in the serum of eight men was 0.14 microgram/liter.

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

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 compar...

Determination of iron in serum or plasma by atomic absorption spectrophotometry.

The determination of serum iron has been shown to be feasible by the use of a modified single-beam atomic absorption spectrophotometer. The effect of interfering substances is eliminated by the use of standards prepared in physiological concentrations of protein. Average percentage recovery of added iron was 97.9 with an over-all coefficient of variation of 1.6%. Disparities between samples due...

Micromethod for determining total iron-binding capacity by flameless atomic absorption spectrophotometry.

Because of the large quantities of venous blood required, assays of total iron-binding capacity (TIBC) and serum iron are often omitted in diagnostic tests involving small children. As an alternative to the conventional method of assessing TIBC, we developed a micromethod based on flameless atomic absorption spectrophotometry (flameless AAS). Additionally, the standard microproc#{233}dure for d...

High-speed automated atomic absorption spectrophotometry.

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...
