MALDI target and Petri dish inserted for transfer of colonies
Pre-deposition of formic acid using liquid deposition needle
Formic acid deposited only on preselected positions
Each selected colony precisely picked...
...and smoothly deposited into formic acid droplet
After drying of all colonies, MALDI matrix is deposited
The unique principle of Wet Deposition (Patent pending) is a key part of our
automated system for colony picking and target deposition, followed by controlled deposition of MALDI matrix.
Wet deposition is a key process for automation in clinical, medical, veterinary as well and pharmaceutical high-throughput microbiology labs that are performing MALDI-TOF MS identification either by Bruker MALDI Biotyper, BioMerieux VITEK MS or any other MALDI-TOF mass spectrometer.
