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...
متن کاملDetermination of mercury by atomic-absorption spectrophotometry.
A flameless atomic-absorption system has been developed for the determination of low concentrations of mercury in gaseous, solid and liquid samples of organic and inorganic materials.
متن کاملDetermination of oxalic acid in urine by atomic absorption spectrophotometry.
A method is described for determination of oxalic acid in urine using atomic absorption spectrophotometry. The concentration of urinary oxalic acid is calculated by using the difference between two determinations of calcium: first, the excess of calcium in the supernatant after precipitation as calcium oxalate at pH 5, and second, the total calcium determined at pH less than 1 (endogenous and a...
متن کاملDetermination of urinary manganese by the direct chelation-extraction method and flameless atomic absorption spectrophotometry.
The direct chelation-extraction method, originally developed by Hessel (1968) for blood lead analysis, has been successfully applied to urinalysis for manganese. The analyses of 35 urine samples containing up to 100 microgram/1 of manganese from manganese-exposed workers showed that the data obtained by this method agree well with those by wet digestion-flame atomic absorption spectrophotometry...
متن کاملDetermination of Trace Copper(II) in Food Samples by Flame Atomic Absorption Spectrometry after Cloud Point Extraction
A new method for the determination of trace copper(II) in food samples by Cloud Point Extraction(CPE) combined with Flame Atomic Absorption Spectrometry(FAAS) is presented and evaluated. The method is based on the fact that hydrophobic complex of copper(II) with sodium diethyldithiocarbamate (DDTC) was formed at pH 6.0 and subsequently the hydrophobic complex was extracted into surfactant-r...
