GD90 Trace: Next-Generation Glow Discharge Mass Spectrometry (GDMS)

Our GD90 Trace system enables full elemental analysis in one scan, detecting concentrations from major components (wt%) down to ultra-trace levels (ppb and sub-ppb). This direct solid-sampling method eliminates the need for chemical digestion, saving time and maintaining sample integrity. 

 The GD90 Trace offers continuously adjustable high-resolution capabilities ranging from <400 to >10,000 RP, meeting diverse analytical needs. Dual collectors provide a wide dynamic range, spanning up to 12 orders of magnitude. 

 Ideal for depth profiling in layered materials, the GD90 Trace performs highly sensitive trace-element distribution analysis without interference from matrix effects. Calibration is simplified using standard Relative Sensitivity Factors (RSF), avoiding the need for matrix-matched standards. 

• Optimized Cell Construction: Durable tantalum cells and source construction simplify cleaning and maintenance. 

• Cryo-Cooling: Optional cryo-cooling of the GD cell reduces gas background, enhancing detection accuracy. 

• Flexible Sample Accommodation: Designed for both pin and flat cell geometries, adaptable to a variety of sample types .

• No Mass Bias: Delivers unbiased results for light and heavy elements alike. 

• Efficient Calibration: Calibration involves a quick check of 180Ta and 181Ta, ensuring consistency between the IC and Faraday detectors. 

• Low Gas Flow Requirements: Optimized for cost-efficient operation using alternative ionization gases, including krypton. . 

• Versatile Sample Compatibility: Analyzes a wide range of samples, from alloys to high-purity materials, in various sample geometries. 

• Low Sputter Rate: Under standard conditions, sputter rates range from 150 nm/min (conductive materials) to 100 nm/min (non-conductive materials), with adjustable rates for more precise analysis.  

• Reliable Detection Limits and RSFs: Detection limits and RSFs are based on well-documented, widely accessible methodologies.  

• Customizable Design for Specialized Applications: Front-end assembly can accommodate a custom glove box for specialized applications, such as nuclear material analysis.
