Gamma Spectrometer
Canberra high resolution Broad Energy germanium (BEGe) detector (BE5030)
with 50% relative efficiency equipped with ultra low background
hardware, an In Situ Object Counting System (ISOCS), mathematical
calibration software, and Genie 2000 Multi-Input software.
Delayed coincidence alpha counters
Two scintillation alpha counters (made by Scientific Computer
Instruments, West Columbia, SC) for measuring the activities
of 224Ra and 223Ra isotopes.
Radon monitor (RAD7)
ICP-MS
VG PlasmaQuad-3 inductively-coupled-plasma mass-spectrometer (ICP-MS)
equipped with the S-option pump for increased sensitivity and a UV
laser-ablation
microprobe for spot analyses to 6 microns (for ultra-trace-element
spot analyses in the
ppb levels). Detection with peak:blank ratios of better than 3:1
has been demonstrated
down to 1 ppt of better for heavier elements (mass greater than 80)
and 5 ppt for most
lighter elements.
DCP
ARL-Fisons Spectraspan 7 direct current plasma (DCP) spectrometer
with a 24
channel multi-element cassette for whole-rock major- and trace-element
analysis (to ppm
levels).
