Unit 1 Overview of Time of Flight Mass Spectrometry Time of flight Mass Spectrometry after been created for a very long time did not become very well known, until its resolution was further improved upon by orthogonal acceleration, reflectrons and high speed electronics. The improved resolution coupled with appropriate ion sources and quadrupole mass filter technology has helped in no small way for the observation of particles that can be separated by gas chromatography. The process of separating ions in TOFMS The time of flight mass spectrometer functions by calculating the mass dependent time for ions whose masses differ from their sources to the detector. This process requires that the time which these ions leave their source is highly characterized. The formation of particles occurs by a pulsed ionization strategy, usually, Matrix Assisted Laser Desorption Ionization (MALDI), or various types of rapid electric filed switching, which aid the discharge of ions from their...
