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: 

  • Extremely short time-to-result: a few minutes for a reliable result
  • High throughput: capability to identify up to 192 isolates per run
  • Less hands-on time: simpler workflow
  • Easy-to-use: no gram staining and microscopic observation is required
  • Fast and flexible method: multiple users can prepare samples simultaneously to save time
  • High performing identification: no need to outsource routine identifications to costly laboratories

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

Dimensions

• 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

Installation Requirements

- 200 VAC, 50/60 Hz, 1000 VA single phase OR

- 230 VAC, 50/60 Hz, 1000 VA single phase

• A ‘clean’, stable and continuous mains supply is required for reliable operation

• Temperature - ambient 18° to 26° C

• Relative humidity - less than 70% non-condensing

• Vibration free, firm, level floor, at least 330 kg supported at four points

Mass range
