High-speed automated atomic absorption spectrophotometry.

Automated atomic absorption spectrophotometry. IV. Simultaneous determination of calcium and phosphate.

‘T1HI5 REPORT presents a procedure for the automated simultaneous determination of both calcium and phosphate, and its application to the analysis of a 0.6-mi. serum specimen. Calcium is determined by atomic absorption spectrophotometry, using a portion of the diluted and dialyzed serum sample (1). Phosphate is determined on the undialyzed residual serum by an improved automated spectrophotomet...

Automated atomic absorption spectrophotometry. II. The determination of serum magnesium.

The flow system developed for the determination of serum calcium by automated atomic absorption spectrophotometry (AAS) was adapted to the determination of serum magnesium. A comparison of the results of analyses by the present procedure and by an automated fluorometric procedure on identical serum specimens shows excellent agreement. from this laboratory described tile application of automated...

Speciation of Arsenic(W) and Arsenic(V) in Sediment Extracts by High-Performance liquid Chromatography-Hydride Generation Atomic Absorption Spectrophotometry

High current–density anodic electrodissolution in flow–injection systems for the determination of aluminium, copper and zinc in non–ferroalloys by flame atomic absorption spectrometry

An automatic procedure with a high current-density anodic electrodissolution unit (HDAE) is proposed for the determination of aluminium, copper and zinc in non-ferroalloys by flame atomic absorption spectrometry, based on the direct solid analysis. It consists of solenoid valve-based commutation in a flow-injection system for on-line sample electro-dissolution and calibration with one multi-ele...

Determination of platinum, palladium, and lead in biological samples by atomic absorption spectrophotometry.

A flameless atomic absorption method for the coextraction of platinum and palladium from biological and environmental samples by high molecular weight amine (HMWA) is given. Also, methods for lead determination in biological samples by use of extraction flameless analysis and direct aspiration-flame analysis are reported. A study of lead contamination of Vacutainer tubes is given.
