electrode), which allow improving the quality of the mass spectrum will be briefly discussed. The measurement of composition based on the time-of-flight mass spectrometry will be presented in the last part of this chapter. This section will review the background subtraction, the definition of int...
MALDI is a soft ionization technique used in mass spectrometry (MS) that produces rapid and efficient ionization of a wide variety of molecules (see Figure 1). MALDI uses a laser energy absorbing matrix to produce ions from molecules having molecular weights ranging from 100's to 1000's of ...
A method and apparatus for performing time of flight mass spectrometry wherein the number of sums of transients taken for generating a given spectra is determined as a function of a characteristic of the incoming data for that spectrum. For instance, the number of transient measurements taken for...
Time-of-Flight Mass Spectrometry Technical Overview John Fjeldsted Agilent Technologies Introduction Time-of-flight mass spectrometry (TOF MS) was developed in the late 1940's, but until the 1990's its popularity was limited. Recent improvements in TOF technology, including orthogonal accelera- tion...

A new on-target deuteration technique in plasma desorption mass Spectrometry (PDMS) is proposed, involving replacing labile hydrogen atoms in a molecule with deuterium atoms. This technique is very simple and allows direct comparison of spectra before and after deuteration for the same probe. The ...
