Lab: Magnetic Sector Inductively Coupled Plasma Mass Spectrometer

Managed by Dr. John N. Christensen
Bldg 70A, rooms 4425-4429, LBNL

The Multi-collector Magnetic Sector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) Laboratory is a facility consisting of two laboratory spaces, one housing the multiple collector mass spectrometer (the IsoProbe, manufactured by Micromass Ltd), and the other containing a clean sample preparation area.

The IsoProbe is equipped with a set of nine movable Faraday cups, two movable channeltrons with ion counting, and an axial Daly ion counting system with a high abundance sensitivity (better than 100 ppb) WARP filter. The ion beam path includes a hexapole gas collision cell, which serves both to focus the beam in energy, as well as providing the means to essentially remove mass interferences due to Ar species. This instrument provides high precision isotopic measurements of a wide range of elements.

Contiguous with the MC-ICPMS lab space, accessible through an airlock, is the sample preparation chemistry clean laboratory. This is a better-than-Class 1000 clean lab environment with HEPA filtered air. It includes both a Class 100 HEPA filtered laminar flow fume hood, a Class 10 ULPA filtered laminar flow fume hood, and a dedicated perchloric fume hood with a wash-down system. ↑Top
