Rb-Sr SYSTEM

Equipment


 
  • KEVEX 770 X-ray Fluorescence Spectrometer, purchased in 1991, allows rapid turnaround and inexpensive analyses for a wide range of elements. These elements can be analyzed quantitatively if suitable standards exist, or semi-quantitatively. The XRF instrument is fully-automated and holds sixteen samples at a time. It uses source-tuned incident x-rays for optimal analysis conditions for a given element and has a high-resolution energy dispersive detector. Located in Denver.
  • MAT 262, purchased in 1993, multicollector (9 collectors), multi-sample (13 samples), mass spectrometer. Fully automated, equipped with an electron multiplier. The instrument is updated with a better water chiller and a newer computer system. Located in Reston.
