SophiTM is a state of the art MALDI benchtop Mass Spectrometer facilitating the rapid identification of micro-organisms AND/OR performing immunoassays that include proprietary approach and methodologies. Its novel electronic and mechanical modules are embedded in a compact and robust design generating the smallest footprint on the market.

The LEXI-MS® is a benchtop MALDI-TOF mass spectrometer optimized for microbial identification. Its hallmark “Dynamic Focusing” ion optics deliver high-resolution performance (3,000 FWHM) across the key microbial mass range (2,000–18,000 m/z) without the need for manual detector tuning. Coupled with an advanced discrete-dynode ETP detector, this system maintains consistent sensitivity even at higher m/z values. Routine MALDI-source maintenance is fully automated by the patented GreenClean procedure, eliminating operator intervention outside of scheduled preventive maintenance.

A dual-output DPSS Nd:YAG laser (355 nm UV at >42 µJ and 532 nm green at >10 µJ) operates from single-shot to 1,000 Hz with <5 % power drift over six hours and pulse‐to‐pulse stability below 2 % RMS. The instrument’s linear TOF design features a 50 cm flight tube allowing detection in both positive and negative ion modes and an extended mass range up to 100,000 m/z. With a warm‐up time under five minutes and compact footprint (82.2 cm H × 67.8 cm D × 48.8 cm W), it balances performance and space efficiency.

Sample handling is streamlined via disposable LEXI plates (84 spots each) and a magnetically locking, barcoded stainless-steel plate holder that accommodates up to three plates (249 samples plus calibrants) with full traceability. Loading three plates takes under two minutes, and the system supports remote diagnostics over TeamViewer for rapid service. Together, these features make the LEXI-MS® a powerful, user-friendly solution for high-throughput microbial mass spectrometry
