Evaluation of a Supercritical Fluid Chromatograph Coupled to a Surface-Wave-Sustained Microwave-Induced Plasma Detector
Abstract
A capillary supercritical fluid chromatograph was coupled to a surface-wave-sustained microwave-induced plasma (MIP) sustained with a surfatron. The chromatographic system, interface, and plasma source are described. The plasma was optimized for sulfur emission at 921.3 nm and used to detect a mixture of sulfur-containing polycyclics that had been separated by SFC. The linear dynamic range for these compounds is 3 orders of magnitude with detection limits of 25 pg/sec of sulfur for thiophene. The relative standard deviations for repetitive injections are typically 1 to 5% at concentrations well above the detection limit. Keywords: Supercritical fluid chromatography; Spectroscopic detector; Speciation; Nonmetal detection; Sulfur analysis.
