Chapter 11, Problem 11.8QAP
Interpretation Introduction
Interpretation:
Description of distance of flight mass spectrometer and the difference between flight mass spectrometer and TOF instrument.
Concept introduction:
Distance of flight mass spectrometer or DOFMS helps in separating the ions which are of different mass-to-charge (m/z) by the distance which is traveled in a given point of time after acceleration.
