The Varian ICP-MS with tunable sensitivity is ideal for environmental, semiconductor, and laser ablation geochemistry applications. With Varian's ICP-MS you can choose workhorse conditions for routine operation at high concentrations and gigahertz performance for the ultimate detection limits.Varian's unique ion-mirror reflects analyte ions through 90 degrees while neutrals and photons pass through the hollow structure. This produces the highest signal-to-background ratio available and the lowest detection limits.The Varian ICP-MS is the world's first ICP-MS with tunable gigahertz sensitivity, providing over thousand million counts per seconds for every part per million. This sensitivity does not compromise performance, with the formation of oxide and doubly charged interferences remaining very low.
