1.	In cases where differentiation is required between very similar substances, which of the following techniques making use of quadrupole principle is preferred?(a) Evaporation mass spectrometry(b) Pyrolysis mass spectrometry(c) Plasma mass spectrometry(d) Trapped ion mass spectrometryI had been asked this question in class test.I'm obligated to ask this question of Quadrupole Mass Spectrometer in division Mass Spectrometer of Analytical Instrumentation
Answer» Right CHOICE is (b) PYROLYSIS mass SPECTROMETRY Explanation: In cases where differentiation is required between very similar substances, pyrolysis mass spectrometry is USED. The sample is USUALLY solid or involatile liquid in this case.
