WebFor example, when using a 100 mm x 2.1 mm ID column, one column volume is 0.2 mL. If we are running an isocratic method with a flow rate of 0.30 mL/min, then the column should be conditioned with at least 10 mL (50 volumes x 0.2 mL volume). The total conditioning time would be 33 min (10 mL ÷ 0.30 min/mL). WebAvailable with Restek's most-popular and highly selective Biphenyl and FluoroPhenyl phases, as well as a general-purpose C18.
