Matrix Assisted Laser Desorption/Ionization Time of Flight (MALDI-ToF)/Mass Spectrometric Immunoassay (MSIA)/Laser Ablation Spectroscopy (LIBS)

Equipment: Applied Biosystems 4800

Working Principle

  • Laser light is used to fragment polymers, proteins, peptides and nucleotides from a sample
  • The fragments are separted and identified by time of flight (neutrals) and mass spectrometer (ions) detectors

Technical Information

  • Mass spectrum of peptides, proteins, small molecules, large molecules, drugs toxins and pathogens
  • Can be used for trace detection of molecules
  • Commonly used for biological samples as a quality control tool
  • Variety of services for labeling available in conjunction with MSIA
