The Platform ICP was the first instrument to use the technique of ICP-HEX-MS to eliminate argon-based interferences and it has been awarded the PittCon Editors’ Gold Award for Best New Product. Platform ICP incorporates HEXTM de-clustering. The procedure involves a hexapole ion lens, located behind the skimmer cone, being surrounded by a gas cell. By admitting small amounts of helium, the pressure over the length of the hexapole is increased, breaking up molecular species before they reach the mass analyser, while the hexapole lens reduces the energy spread of the ions as they emerge from the skimmer. Detection limits for most elements are in the ppt range, including previously difficult elements such as K, Ca, Fe, Se and As. Platform ICP uses a new type of detector for ICP-MS. Micromass’ DynoliteTM detector technology is a wide dynamic range photomultiplier detector, which gives eight orders of magnitude without changing detection mode thereby eliminating cross calibration and reducing analysis times.
