In two configurations, a solid-state acousto-optic (AO) deflector or modulator is mounted in a 0.5 m monochromator for background correction with inductively coupled plasma atomic emission spectrometry (ICP-AES). A fused silica acousto-optic modulator (AOM) is used in the ultraviolet (UV) spectral region applications while a glass AO deflector (AOD) is used for the visible (VIS) region. The sys...

Four tests for the evaluation of lead poisoning are reviewed from both the clinical and methodological aspects. Whole blood or erythrocyte lead measurements appear to provide the best means of assessing the bodily burden of lead with electrothermal and Delves cup flame atomic absorption spectorphotometric techniques providing accurate and precise results. Urine lead is less reliable as a screen...

The dependence of the color of quartz and opal natural minerals, collected from different localities in the Republic of Macedonia (Alinci, Belutče, Budinarci, Mariovo, Sasa, Saždevo, Čanište, Češinovo, Zletovo) on their element composition is studied using Fourier transform infrared spectroscopy (FT IR), micro-Raman spectroscopy and atomic absorption spectrometry (AAS). In order to determine th...

An electrodeposited palladium and iridium/gold mixture has been investigated as a chemical modifier for mercury determination in environmental samples by solid sampling electrothermal atomic absorption spectrometry. Electrochemical procedures of platform surface modification performed in a cell with 20 ml of solution, and in a drop of modifier solution have been optimized. Simple electrolysis i...
