The W.M. Keck Isotope Laboratory comprises two mass spectrometers and wet chemical labs all housed in a class 1000 suite of clean labs. The laboratory was inaugurated on 18th June 2004 following a substantial grant from the W.M. Keck Foundation for the purchase of a ThermoFinnigan Neptune multiple collector ICP-MS. Within the W.M. Keck Isotope Lab is a thermal ionization mass spectrometer (TIMS)- a fullyautomated, nine- Faraday collector VG Sector 54 equipped with a WARP filter and an ion counting Daly. This instrument is typically used for Rb-Sr, Sm- Nd, Pb, U, Th, Ra and Ca isotope measurements. The Sector 54 has been recently upgraded to ensure continued high precision performance.The Neptune was acquired in 2003 through a grant from W.M. Keck foundation. It is a multiple collector inductively coupled plasma mass spectrometer (MC-ICP-MS) equipped with nine Faraday collectors and 4 ion counters. One of these ion counters is located behind an RPQ filter to give high abundance senstivity. The Neptune offers high precision isotope measurements for almost all elements in the periodic table. The instrument is typically used for Pb, Nd, Hf, U, Th, Fe, Cr and Mo isotope analyses. The UCSC stable isotope facility has two mass spectrometers, a FISONS Optima, and a FISONS Prism. Both are equipped with automatic carbonate devices. In addition the Prism is fitted with the VG “Multiprep” autosampling system for carbonates and oxygen analyses of waters. The OPTIMA is fitted with a Carlo-Erba CHN Analyzer for continuous flow measurement.
