1.	Which of the following has to be done to increase the resolution of the quadrupole mass spectrometer?(a) Increasing distance between detector and reflectron(b) Increasing difference between the individual rf accelerating stages(c) Increasing the length of the drift tube(d) Increasing the rod length of the electrodeThis question was addressed to me in an online quiz.My enquiry is from Quadrupole Mass Spectrometer in portion Mass Spectrometer of Analytical Instrumentation
Answer» Right answer is (d) Increasing the ROD length of the ELECTRODE Easiest explanation: The resolution DEPENDS UPON the electrode. The length of the electrode has to be INCREASED for increasing the resolution.
