Mass spectrometry for microbial identification : the MALDI-TOF technology

The VITEK® MS system relies on mass spectrometry, an analytical technique which determines the elemental composition of a sample. It is the latest technology for microbial identification

MALDI-TOF : Matrix Assisted Laser Desorption Ionization – Time of Flight analyzer


To perform identification, the sample to be analyzed is mixed with another compound : the matrix. When the mixture is applied to a metal plate and irradiated with a laser, the matrix vaporizes and the sample gains an electrical charge, whose mass-to-charge ratio is measured.

To identify microorganisms, the VITEK® MS:

  • Ionizes the sample thanks to matrix and laser reaction
  • Uses an electric field to accelerate the ions through the same potential
  • Measures the time they take to reach the detector – Time of Flight
  • Spectrum is sent and compared to a database


• 337 nm nitrogen laser, fixed focus

• Maximum pulse rate - 50 Hz (50 laser shots per second)

• Near normal (on-axis) incidence of the laser beam to the sample

• Laser power and laser aim under software control


• Linear flight tube of 1.2 m drift length

• Vacuum maintained by two turbomolecular pumps (nominal 250 l/s) with rotary backing

• Beam blanking to deflect unwanted high intensity signals e.g. matrix ions


• Size (w h d) - 0.7 m x 1.92 m x 0.85m, minimum distance to wall at back is 100 mm

• Weight - 330 kg excluding data system
