Nu Astrum ES GD-MS

• Double-focusing mass spectrometer with electrostatic and magnetic sectors for high mass resolution and effective separation of analytes from spectral interferences.
• Adjustable high-resolution capability ranging from approximately 400 to over 10,000 (10% valley definition), supporting challenging elemental analyses.
• High-sensitivity glow discharge ion source based on proven technology, providing stable ion generation and straightforward calibration.
• Wide dynamic range achieved through the combination of Faraday detection and ion-counting electron multiplier, enabling simultaneous measurement of major and ultra-trace elements.
• Single-scan detection of impurities at sub-ppb concentrations, improving analytical efficiency for high-purity materials.
• Flexible sample accommodation with both pin and flat sample holders for a variety of solid sample geometries.
• Dedicated low-temperature cooled source for analyzing low-melting-point materials while minimizing background gas contributions.

The Nu Astrum ES GD-MS is primarily employed for the elemental characterization of high-purity inorganic solid materials where ultra-low impurity levels are critical. Its capability to measure virtually the entire periodic table with minimal matrix effects makes it an effective solution for trace elemental analysis in advanced materials. Typical applications include the characterization of high-purity metals and alloys, such as nickel-based superalloys for aerospace applications, as well as semiconductor materials including high-purity copper and silicon. The instrument is also widely used for the analysis of gallium-based materials supporting LED manufacturing, high-purity graphite, and other electronic materials requiring stringent impurity control.

With the ability to analyze conductive, semiconductive, and insulating solids in different sample forms while providing elemental depth profiling, the system supports quality control, materials development, process optimization, and failure investigation across industries where material purity directly influences product performance.
