WebTo simulate usual chromatographic practice, the columns were subjected to stability testing by washing the stationary phases at a flow rate of 0.8 mL min-1 to 10000 mobile phase volumes at 40 °C and then to 15000 mobile phase volumes at 60 °C. During this program, tests were periodically performed (at 0.2 mL min-1) using 60:40 v/v ethanol:water for the … WebMonoCap C18 Trap Columns. MonoCap Trap columns have a relatively big throughpore and workable at a high flow rate such as 10 μL/min. This benefit makes MonoCap Trap columns to be appropriate for on-line pre-concentration or desalting of protein and peptide samples prior to HPLC separation with mass spectrometry detection. End-fittings are …
