Laser Ablation Electrospray Ionization (LAESI) Mass Spectrometry: matrix-free ambient 2D or 3D imaging of living tissue without sample preparation

006-000x-vertes – LAESI provides very precise in situ chemical analysis of biological samples using mass spectrometry (MS) technique. LAESI enables 2D and 3D imaging of metabolites, lipids, peptides and proteins in biological samples at the single cell level, empowering rapid chemical analyses in multiple fields of biology, medicine and chemistry. The LAESI device embodies an ionization source / sample... Read More

Matrix-free Mass Spectrometry on Nanopost Array (NAPA) Chips

009-000xb-vertes – Silicon NAPA chips provide highly efficient ion production for ultratrace analysis and molecular imaging by mass spectrometry without an ionization matrix. Matrix-assisted laser desorption ionization (MALDI) is an established ionization technique for mass analysis of large biomolecules, but analysis of small biomolecules (m/z < 1000) suffers from matrix-related interferences. For this... Read More
