Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. The velocity of the ion depends on the mass-to-charge ratio. In general, MALDI-TOF/TOF instruments are characterized by a co-linear arrangement of two TOF mass analyzers, each equipped with an ion source that allows acceleration and focusing of the ions. In TOF1 the analyte ions are accelerated, precursor ions are selected and fragmented

Maldi tof 1. Maldi Tof - Purvi Gosrani 2. Introduction Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique used in mass spectroscopy, allowing the analysis of biomolecules (biopolymers such as DNA, Proteins, peptide and sugars) and organic molecules (such as polymers, dendrimers and other macromolecules), which tend to be fragile and fragment when ionized by more. A comparative study on the three quantitative methods frequently used in proteomics, 2D DIGE (difference gel electrophoresis), cICAT (cleavable isotope-coded affinity tags) and iTRAQ (isobaric tags for relative and absolute quantification), was carried out. DIGE and cICAT are familiar techniques used in gel- and LC-based quantitative proteomics, respectively. iTRAQ is a new LC-based technique.
