Direct determination of zinc in serum by Zeeman atomic absorption spectrometry with a graphite furnace.
We developed a precise and accurate graphite furnace atomic absorption spectrometric method for the direct determination of zinc in serum. Serum samples are analyzed after 20-fold dilution with water of ultrapure analytical grade. No other reagent is used, from the moment of sampling until measurement. During atomization, the argon flow is kept at 150 mL/min instead of gas stop, to decrease the...
متن کاملMicromethod for lead determination in whole blood by atomic absorption, with use of the graphite furnace.
I describe a micro-scale method for determining lead in whole blood by utilizing a graphite furnace. Sample pretreatment consists of fivefold dilution with a dilute surfactant. The method is directly calibrated with lead standards prepared in dilute HNO3. To eliminate a small, nonspecific absorption signal from the blood matrix, simultaneous background correction is used. Interlaboratory co...
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 کاملAluminum determined in plasma and urine by atomic absorption spectroscopy with a transversely heated graphite atomizer furnace.
We compared a stabilized-temperature L'vov platform furnace containing an end-heated graphite atomizer (HGA) and transverse Zeeman background-correction system with a side-heated furnace system (transversely heated graphite atomizer; THGA) containing a longitudinal Zeeman background-correction system for the determination of aluminum in plasma and urine. The regression statistics for the correl...
