The GD90 is a high resolution offering direct determination of elemental content (matrix to subtrace) in a variety of materials. Glow Discharge mass spectroscopy is a mature, versatile technique for the direct determination of elemental content (matrix to sub-trace) in a variety of materials. Glow discharge occurs on a molecular level by applying a potential difference between the anode and the cathode (analyte). As atomisation and ionisation occur separately, minimal matrix effects are observed.
