25 October 1999 Diode laser spectrometry of environmental and industrial samples
Author Affiliations +
Small, robust, powerful and easy to operate instruments based on atomic absorption spectrometry with diode lasers has been developed. The instruments allow measurements of trace element concentrations as low as about 1 pg/g. This was demonstrated by the measurement of trace elements on silicon wafers and ultra pure chemical reagents in semiconductor industry, the detection of chlorine in polymers, and element selective detection in GC and HPLC.
