The Technology Behind MALDImini-1

Compact design with unique ion optics system and layout MALDImini Console

The laser optic system, sample stage, and vacuum exhaust system have all been nely optimized to reduce the size of the device. With the dedicated control software for MALDImini-1, you can take measurements just by setting simple analysis parameters. Switch

Ion and laser optics steer the laser beam to hit the sample orthogonally to the plate,
enabling high ion transmittance and a more compact layout. Following ionization,
the beam is de ected 90° to ensure maximum transfer of ions to the ion trap. 3

Digital Ion Trap (DIT) technology provides high sensitivity over a
wide mass range, despite the device's small footprint

The world- rst* Digital Ion Trap (DIT) technology, unique to Shimadzu, uses rectangular wave RF to trap ions rather than the sine Compatibility with software solutions
wave RF which has been used in ion-trapping devices until now.
Powerful processing tools can be used to analyze your exported mzML or mzXML data, such as MASCOT for identifying protein
digests, SimGlycan for processing MS data for glycans, and eMSTAT Solution for statistical analysis.
