Review:
Maldi Tof Mass Spectrometer
overall review score: 4.6
⭐⭐⭐⭐⭐
score is between 0 and 5
The MALDI-TOF mass spectrometer (Matrix-Assisted Laser Desorption/Ionization - Time of Flight) is an advanced analytical instrument used to identify and analyze biomolecules, such as proteins, peptides, nucleic acids, and small organic compounds. It operates by ionizing samples with a laser in the presence of a matrix, then measuring the time it takes for ions to travel through a flight tube, allowing precise determination of their mass-to-charge ratios. This technique is widely used in clinical diagnostics, microbiology, proteomics, and research laboratories for rapid and accurate molecular analysis.
