Description

The MALDI-7090™ MALDI-TOF mass spectrometer represents a new generation of high-performance systems specifically designed for the identification and structural analysis of biomolecules with maximum efficiency and precision. The instrument incorporates a suite of advanced SHIMADZU technologies in mass spectrometry, providing outstanding stability, sensitivity, and reproducibility of measurements.

The high-performance MultiPlex platform enhances productivity by combining a simultaneous loading system for up to 10 MALDI plates, an ultrafast 2 kHz solid-state UV laser, and the multi-user operating mode of MALDISolution™ software. Prepared plates can be loaded or unloaded even during measurement operations. The loading chamber can operate under atmospheric pressure or be purged with nitrogen to protect labile samples.
