ICP-MS stands for which term?

ICP-MS stands for which term?

• A. Inductively Coupled Plasma Optical Emissions Spectronomy
• B. Inductively Coupled Plasma Mass Spectronomy
• C. American Industrial Hygiene Association
• D. Non-Governmental Organization

Answer: (B)

ICP-MS combines an inductively coupled plasma to ionize the sample with a mass spectrometer to separate and detect those ions by their mass-to-charge ratio. That direct naming matches Inductively Coupled Plasma Mass Spectrometry, the correct term for this instrument. The other options point to unrelated ideas: one describes a different detection method that uses optical emission (not mass analysis), and the remaining two are organizations, not instrumentation. So the best answer is the one that explicitly names mass spectrometry after the inductively coupled plasma.
