VITEK^® MS database: the pillars for high performance

The system database contains a large number of specific microorganisms, increasing identification accuracy.

• Species represented by population: specific species’ characteristics can be revealed
• Average of 18 isolates per species from different fields (clinical, food and pharma) and geographical origins (Asia, America, Europe)
• Average of 40 spectra per species: several culture media and instruments

Benefits of the VITEK^® MS identification system

State-of-the-art system, VITEK^® MS is the future of microbial identification:

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

Laser

• 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

Analyzer

• 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
