ICP-MS spectrometers

Inductively coupled plasma mass spectrometry

ICP-MS uses argon plasma to ionise samples and a mass analyser to separate ions by mass-to-charge ratio. Applications include trace element determination and isotope analysis in water, materials and prepared laboratory samples.

Selection parameters

• Target elements, concentrations and sample matrices.
• Mass analyser type and spectral interference control.
• Collision or reaction cells and operating gases.
• Sample introduction, autosampler and acid resistance.
• Reagent purity, sample preparation, cooling and extraction.

Also compare ICP-OES spectrometers for optical emission analysis. Required sensitivity should be assessed for the specific method and matrix.
