Figures of merit for a direct injection nebulizer for flow injection analysis and liquid chromatography with inductively coupled plasma spectrometric detectionChakrabarty, Chitra L. January 1990 (has links)
A direct injection nebulizer was constructed in our laboratory and was evaluated as an interface between a liquid chromatography column and an inductively coupled plasma-atomic emission spectrometer (ICP-AES). Optimum operating conditions, detection limits, and reproducibility in water and in organic solvents were studied. The detection limits in water were similar to a commercially available device. The detection limits of elements in organic solvents were about ten times higher than those in water. The DIN-ICP system stave more uniform response towards different species of Phosphorus and osmium than did a Meinhard nebulizer-ICP system, even when great differences in volatilitN existed between the species. A Potential application to the speciation of cisplatin and its analogs was also investigated. / Department of Chemistry
