Dt. Gjerde et al., METAL SPECIATION BY MEANS OF MICROBORE COLUMNS WITH DIRECT-INJECTION NEBULIZATION BY INDUCTIVELY-COUPLED PLASMA-ATOMIC EMISSION-SPECTROSCOPY, Journal of chromatography, 640(1-2), 1993, pp. 73-78
Ion chromatography can be used to perform speciation of several elemen
ts. This paper examines the use of ion chromatography with inductively
coupled plasma atomic emission spectroscopy detection. A new type of
nebulizer, the direct-injection nebulizer, was used to introduce the s
ample into the plasma. Columns were developed to interface with the di
rect-injection nebulizer at a flow-rate of 80-100 mul/min. The speciat
ion of arsenic, selenium and chromium is discussed.
