The Bruker Microflex is a Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometer (MALDI-TOF MS), primarily used for rapid identification of microorganisms, biomolecules (like proteins and peptides), and polymers. It is part of Bruker’s MALDI Biotyper series

Key Components:

Laser Source: Nitrogen or solid-state laser (commonly 337 nm UV)

Ion Source: Vacuum chamber with MALDI target plate

Flight Tube: Measures time-of-flight of ions

Detector: Converts ion arrival times into a mass spectrum

MALDI Target Plate: Metal plate for spotting samples mixed with matrix

How It Works (Simplified):

Sample Prep: Mix analyte with a MALDI matrix (e.g., α-cyano-4-hydroxycinnamic acid).

Laser Ionization: Laser hits the matrix, causing it to ionize the sample.

Ion Acceleration: Ions accelerated into TOF analyzer.

Detection: Time-of-flight is measured; smaller ions reach the detector faster.

Spectrum: Mass/charge ratio (m/z) plotted vs intensity.

Physical Specs (Approximate):

Footprint: Desktop size (about 80 cm width)

Weight: ~100–120 kg (varies by model/version)

Power: Standard lab electrical supply

Environment: Requires clean, stable temp/humidity condition
