ICP-MS Cones

(Showing 4 of 4)

ICP-MS sampler and skimmer cones are precision-machined interface components that sit at the heart of the ion extraction process, and their condition has a more direct impact on instrument sensitivity, background levels, and signal stability than almost any other consumable in the system. Deposits of matrix material, oxide formation, and physical erosion of the cone orifice from high-dissolved-solids samples progressively degrade ion transmission, increase oxide and doubly-charged species interferences, and introduce instability that manifests as drift across long analytical sequences. Cone material selection — nickel for standard aqueous and environmental matrices, platinum for hydrofluoric acid and highly corrosive sample streams, and aluminum for high-matrix applications — must match the chemistry of the method to achieve acceptable cone lifespan and maintain the performance specifications required for trace-level compliance work.
