1.	Which of the following is placed just before the detector in a radiofrequency mass spectrometer?(a) Ion source(b) Potential energy selector(c) Ionisation chamber(d) ReflectronI had been asked this question in an interview.I'd like to ask this question from Radiofrequency Mass Spectrometer topic in section Mass Spectrometer of Analytical Instrumentation
Answer» Correct option is (b) POTENTIAL energy SELECTOR The EXPLANATION: A potential energy selector is placed before the detector. It balances out the energy of the ION BEAM.
