Direct Determination of Manganese in Perspiration and Urine Using Atomic Absorption Spectroscopy

Abstract

The analysis of biological samples such as perspiration and urine is made difficuly by the high solids content, and variable organic content of these samples. Sample pretreatment can result in sample loss and/or sample contamination. Graphite furnace atomic absorption provided a rapid and accurate means of analysis of complex biological samples sufficiently sensitive for the direct determination of manganese, without the errors involved in preconcentation and pretreatment of samples required with less sensitive methods.
