BELOW: Flow rate comparison for a 5-peptide mix: A) Spectra for 500 nL/min. constant flow rate; B) Spectra for 50nL/min. constant flow rate; C) Intermediate flow rate

Rapid Method Development: Methanol vs. Acetonitrile

For a 5-component angiotensin sample, methanol yielded superior performance with enhanced MS S/N ratios and peak intensities. Below, base peak chromatogram of 5-angiotensin test mixture using a PicoFrit® column containing 10 cm of ProteoPep™ II C18.
