Optimum flow rate
WebOct 12, 2016 · The optimum flow rate for resolution of proteins is approximately 2 mL/cm 2 /h, although much higher flow rates can be used, particularly with rigid matrices such as the Sephacryl HR range from GE Healthcare (30 mL/cm 2 /h). Unfortunately, low flow rates mean longer separation times. WebFlow rates are typically 200 to 300 mL/min. Microbore columns are usually 1 mm or less in diameter with flow rates about 50 mL/min. When using narrower diameter columns, the …
