Glow Discharge Mass Spectrometry (GD-MS)

Glow discharge mass spectrometers enable you to define new standards in the direct analysis of solid samples, providing you with the solution of choice for high throughput determination of trace elements in high purity conductive and semi-conductive materials.

Providing complete material characterization for high purity metals and alloys, semicon and battery applications, the Thermo Scientific Element GD Plus GD-MS system features a fast glow discharge ion source in a high-resolution mass spectrometer. The ideal tool for the direct analysis of high purity conductive and semi-conductive materials, the system can detect and routinely quantify almost all elements present in a solid sample at or below the ppb range.

The fast flow source offers uniquely high sensitivity and low levels of interferences. Additionally, the fast flow source enables rapid pump down and sample acquisition times, dramatically improving sample through-put and lab productivity. 

The simplicity of high-resolution ICP-MS allows the most advanced performance, without compromising on straightforward and reliable method development. The Element GD Plus GD-MS provides interference free measurements, resulting in simple linear calibration curves for quantification. Three fixed resolution settings (300, 4,000, 10,000), with switching times of <1 s, ensure optimum conditions to reliably remove spectral interferences. The fixed-slit design guarantees maximum stability and reproducibility.

Typical applications involve the simultaneous analysis of matrix elements (%), traces (ppm) and ultra-traces (ppb). To achieve this, the detection system offers a fully automatic detector with >12 orders of linear dynamic range with automatic cross calibration between different detection modes. 

The quantification of gas phase elements like trace carbon, nitrogen and oxygen within materials has traditionally been accomplished through combustion techniques, requiring a second analytical instrument. The CNO option of the Element GD Plus GD-MS cleans the argon discharge gas through purification units adsorbing moisture, carbon dioxide and nitrogen traces from the argon gas supplied. This allows sub-ppm limits of detection to be achieved for carbon, nitrogen and oxygen.

• Unique design providing highest accuracy and widely adjustable sputter rates suitable for bulk analysis and depth profiling
• High sensitivity for short analysis times
• Fast and simple sample to sample switching
• Low level of polyatomic interfaces without the need for cryogenic cooling
• Flexible cell for flat samples, pressed powders and pin samples
• Plug-in cone and anode parts for quick exchange to avoid sample carry over

Even the most sophisticated elemental analysis is made more straightforward with the right GD-MS accessories. Improve performance, convenience and flexibility with accessories designed specifically for your glow discharge mass spectrometer.
