This system includes:. (1) Varian 820MS ICPMS. (1) Agilent SPS 3 or ASX-500 sample preparation system. (1) Circulating cooler. (1) Rough pump. (1) PC with data. The Varian 820-MS system is a compact, floor-mounted ICP-MS (Inductively Coupled Plasma Mass Spectrometer) with full PC control of all instrument settings and compatible accessories. It features a patented 90-degree reflective ion optics system that provides gigahertz sensitivity (1000 Mc/s/mg/L) and low background and interference. The Varian ICP-MS systems include a sample delivery system, a fixed 27 MHz RF generator and patented Turner braided coils. Full PC control of the plasma positioning, three-stage vacuum system, all plasma gas streams, mass analyzer and discrete dynode electron multiplier (DDEM) detector is also included. The vacuum system is fully built into the instrument, ensuring the smallest possible instrument footprint. The unique DDEM detector offers nine decades of dynamic range in an all-digital pulse design. The Varian 820-MS system also features a unique Collision Reaction Interface (CRI) that enables fast, flexible, trouble-free analysis with simple collision and reaction gases. Features include:. Range from 3 to 256 amu. Scan speed: 2000 amu/s. Quadrupole RF frequency of 3. 0MHz. 27. 12MHz solid state, air cooled, crystal locked RF generator. Detection limits as low as 0.05 ng/L for some elements Labprocure bears responsibility for this device.
