Mass spectrometry for microbial identification: the MALDI-TOF technology
he 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
