ICP-MS (Inductively coupled plasma mass spectrometry) is the accepted and most powerful technique for the analysis and quantification of trace elements in both solid and liquid samples.
Its applications range from routine environmental analyses and geological applications, through to clinical research, material sciences and the semiconductor industry.
It is based on coupling together an Inductively coupled Argon Plasma as a method of producing Positive ions with a Mass spectrometer, as a method of separating and detecting the ions.
The ICPMS can be used for low level elemental analysis of samples in solution. The detection limits are typically low ug/l levels (ppb) or ng/l levels (ppt), depending on the analyte and or Matrix.
It is also possible to analyse solid samples using laser ablation as the sample introduction technique. A laser ablates the solid sample to create a gas/cloud which is introduced into the ICP Torch.
