A Benchtop Inductively Coupled Plasma Mass Spectrometer
The HP 4500 is the first benchtop ICP-MS. It has a new type of optics system that results in a very low random background and high sensitivity, making analysis down to the subnanogram-per-liter (parts-per-trillion) level feasible. It can be equipped with HP’s ShieldTorch system, which reduces interference from polyatomic ions.
