Advion have introduced the ‘Tides Express proteins and peptides analysis system. It combines Advion’s HPLC system and the extended mass range ExpressionL compact mass spectrometer. It will help chemists performing peptide synthesis and needing fast mass analysis of each reaction step and final product. It will also find use in solid-phase peptide synthesis, which allows for rapid, parallel synthesis of peptides of various amino acid lengths. Rapid analysis of each reaction step can prevent a sub-optimal synthesis cycle from causing re-runs. Additional fragmentation analysis and charge deconvolution tools enhance its use for protein characterisation.
