Determination 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 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 cadmium in blood by use of atomic absorption spectroscopy with crucibles--and a rational procedure for dry-ashing.
A simple, minimal-reagent procedure for analysis of cadmium in blood is introduced. Blood samples from workers occupationally exposed to cadmium were collected with heparin. Titon X-100 surfactant was added, and 15-mul aliquots of the blood were pipetted into small nickel sampling cups and placed in a holder for 100 cups, which was enclosed in a stainless steel box. After the samples were drie...
متن کاملHigh-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...
متن کاملComparative sensitivities of flame atomic absorption spectrophotometry (AAS) and molecular absorption spectrophotometry (MAS).
A sensitivity comparison was made between conventional atomic absorption spectrophotometry (AAS) and conventional molecular absorption spectrophotometry (MAS) for the serum trace metals, copper, iron, and zinc. The sensitivity aspect considered was absorbances was obtained for concentrations in the solutions analyzed using unit lightpaths of 1 cm and 10 cm for MAS and AAS, respectively. A disti...
