  1. Pick colony
  2.  Direct deposit on the slide
  3.  Add ready-to-use CCHA Matrix (Formic Acid – Yeast)
  4.  Load into VITEK® MS
  VITEK® MS target slides have unique barcode, so high traceability is ensured for each sample

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:
  • Ultra fast time-to-result: minutes for a reliable result
  • High throughput: 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
  • Informative and easy-to-read results
  • Traceability: slides are barcoded and software is easy-to-use
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
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
