1.	In glow discharge ion source, the sample is atomised by which of the following process?(a) Evaporation(b) Sputtering(c) Heating(d) AnnealingI had been asked this question in a national level competition.This intriguing question comes from Components of Mass Spectrometer topic in division Mass Spectrometer of Analytical Instrumentation
Answer» CORRECT option is (b) Sputtering To elaborate: In glow discharge ion source, the sample is atomised by the PROCESS of sputtering. It not only atomizes the sample but ALSO provides means by which these atoms are IONIZED.
