HTX M5 Sprayer
Equipment overview
The HTX M5 Sprayer is an advanced, automated matrix deposition system designed primarily for Mass Spectrometry Imaging (MSI) applications, such as MALDI-MSI sample preparation. Built on the foundation of previous models, the M5 features an upgraded chassis, high-velocity XY stage, and an integrated heated sample tray/drawer.
Major applications
Its primary purpose is to apply a precise, highly uniform coating of matrix solutions (or enzymes like trypsin for on-tissue digestion) onto tissue samples or MALDI plates. This guarantees fine crystal formation and optimal analyte extraction while minimizing analyte delocalization, yielding high spatial resolution and robust relative quantification.
