Automatic microbial mass spectrometry detection system-CMI-1600

CMI-1600 is a mass spectrometry detection system based on matrix assisted laser desorption ionization (MALDI), which was independently and positively researched and developed by Hexin Kangyuan for 5 years after fully mastering the core technology and advanced manufacturing process. Compared with traditional microbial identification technology, mass spectrometry identification has obvious advantages such as fast identification speed, high accuracy, low technical cost and convenient operation.

Principles of the instrument

MALDI: the analyte is dispersed in the matrix molecules and forms cocrystallization. When the crystal is irradiated by laser, the sample molecules obtain energy desorption, and the matrix ions ionize the sample by charge transfer.

TOF-MS: after accelerating in the electric field, ions enter the area without electric field and are detected according to the different flight times of arriving at the detector, that is, ions are detected by determining that the mass charge ratio (m/z) of ions is in positive ratio to the flight time of ions.

Application

Clinical microbiological identification

Identification of pathogenic microorganisms at CDC

Detection of microbial contamination in food and drug administration
