Zinc Determined in 1O-/2L Serum or Urine Samples by Flameless Atomic Absorption Spectrometry
We describea preciseflameless atomicabsorption spectrometric method requiring only 10 tL ofsample, which thus permits repeated measurements in the neonate. Standard curves covering the range of 0 to 30 mg of zinc per liter, with standards in various matrixes (albumin, glycerol, serum, or nitric acid) hadslopesranging from 0.49 to1.17, relative tothatforaqueousstandards. We prepared low-zinc mat...
متن کاملDirect determination of lead and cadmium in blood and urine by flameless atomic absorption spectrophotometry.
We describe procedures for direct determination of lead and cadmium in blood and urine by flameless atomic absorption spectrophotometry. Before analysis, the samples are pre-ashed in microboats in an ordinary laboratory oven. In this way, many samples can be prepared and pre-ashed simultaneously. We find the procedures presented in this work to be rapid, accurate, and precise.
متن کاملDEVELOPMENT OF A METHOD FOR ALUMINIUM DETERMINATION IN SERUM AND DIALYSIS FLUID BY FLAMELESS ATOMIC ABSORPTION WITH GRAPHITE FURNACE
Aluminium determination was carried out in serum and dialysis fluid by a simple and reliable method of nameless atomic absorption with graphite furnace . . No preparatory procedures are required for water and dialysis fluid. In this method serum was mixed with 0.2% HNO, to allow complete combustion of the samples in order to improve analytical precision. The method has a sensitivity of 15 p...
متن کاملDetermination of diethyllead in the urine by flameless atomic absorption spectrometry.
A method for the determination of diethyllead in urine by flameless atomic absorption spectrometry after chelation with glyoxal-bis (2-hydroxyanil) and extraction of the formed complex with methyl isobutyl ketone is described. The method is specific in relation to both triethyllead and inorganic lead. The limit of detection was 3.2 micrograms Pb/l and the relative standard deviation in the conc...
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...
