Bruker Maldi-Tof Microflex Mass Spectrometer

This listing is for the Bruker microflex mass spectrometer. The unit is in full working condition and is ready for immediate use. 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.
