A Fundamental Study of the Microwave Induced Plasma Gas Chromatography Detector
Characterization of the Microwave-Induced Plasma as a Detector for Supercritical Fluid Chromatography
Author: Leonard J. Galante
Publisher:
ISBN:
Category :
Languages : en
Pages : 42
Book Description
A microwave induced plasma (MIP) sustained in helium is evaluated as an element selective detector for capillary supercritical fluid chromatography (SFC). The plasma source, a surface microwave induced plasma (surfatron), is described. Optimal plasma conditions including viewing position, helium flow rate, and applied microwave power are discussed for sulfur emission in the near-infrared spectral region. In addition, the effects of two common mobile phases (CO2 and N2O) on plasma stability, sensitivity, and spectral background from 200 nm to 1100 nm are assessed. Although the plasma was evaluated principally for use with SFC, much of the discussion is relevant to its application as a gas chromatographic detector. Keywords: Supercritical fluid chromatography; Nonmetal detection; Spectroscopic detector; Speciation; Sulfur detection. (jd/rh).

Book Description
This report describes the results of a study to improve the capabilities of a gas chromatography-microwave-induced plasma (GC- MIP) detector system, determine the feasibility of empirical formula determination for simple mixtures containing elements of interest to fossil fuel analysis and, subsequently, explore applications for analysis of the complex mixtures associated with fossil fuels. The results of this study indicate that the GC-MIP system is useful as a specific-element detector that provides excellent elemental specificity for a number of elements of interest to the analysis of fossil fuels. It has reasonably good sensitivity for carbon, hydrogen, sulfur, and nickel, and better sensitivity for chlorine and fluorine. Sensitivity is poor for nitrogen and oxygen, however, probably because of undetected leaks or erosion of the plasma tube. The GC-MIP can also provide stoichiometric information about components of simple mixtures. If this powerful technique is to be available for complex mixtures, it will be necessary to greatly simplify the chromatograms by chemical fractionation. 38 refs., 46 figs., 16 tabs.
