Ion Source Board and Turbomolecular Pump

The U.S. Geological Survey (USGS) Water Mission Area has a requirement to purchase one Ion Source Board and one Turbomolecular Pump. The Ion Source Board is a printed circuit board that fits inside a mass spectrometer and provides the voltages and currents needed to produce ions in the mass spectrometer for analysis. The Turbomolecular Pump evacuates the mass spectrometer to the required vacuum. The equipment will be used as spares for the USGS’s Thermo isotope-ratio mass spectrometers. • The Ion Source Board must be mechanically and electronically compatible with Thermo Delta V Plus isotope-ratio mass spectrometers • The Ion Source Board must be controllable using Thermo ISODAT data acquisition and control mass spectrometer software • The Turbomolecular Pump must be equivalent with Thermo part number 1289010 or equivalent pump • The Turbomolecular Pump must be controllable using Thermo ISODAT data acquisition and control mass spectrometer software • The equipment must be delivered within 3 months of receipt of order • No installation or training is required • A minimum warranty of 90 days for the Ion Source Controller Board and 1 year for the Turbomolecular Pump is required
