Glow Discharge MS
The Astrum is designed to test high purity materials with the best detection limits. The primary application of the Astrum GD-MS is the characterisation of high purity conductive and non-conductive materials. It is capable of quantifying virtually all elements from lithium to uranium and from matrix to sub part-per-billion. The instrument combines a glow discharge ion source with a high resolution mass spectrometer and is considered to be a major step forward in GD-MS, from the cryo-cooled tantalum source and rapid sample changeover system through to the bespoke control software.
