Select Series MRT Desorption Electrospray Ionization (DESI) system for sample preparation free tissue mass spectrometry imaging with superior molecular class coverage.

Desorption electrospray ionisation mass spectrometry imaging (DESI MSI) provides excellent metabolic coverage and throughput with minimal sample preparation for tissue imaging in pre-clinical and clinical studies. Waters produce the only commercially available DESI MSI system. This latest innovation (Select Series MRT with DESI XS source) builds substantially on their previous DESI systems enabling superior image resolution, useability, reliability, mass accuracy < 1ppm and mass resolving power of > 200,000 at scan...
