Chromatography problems!

  1. Sep 23, 2004 #1
    hi guys!

    i am doing the chromatography. in scaling up i have to increase my volumetric flow rate but maintain my linear flow rate. my problem is i don't know how to calculate the column cross sectional area (cm2). i hope you guys who work with this area can tell me how i can calculate it when the radius of the column is 3cm and the height is 15cm.

    Linear flow rate (cm/hr) = volumetric flow rate (cm3/hr) /
    column cross-sectional area (cm2)

    thanks a bunch!

    Cross section of a column should just be area of a circle. pi*r^2
    ...unless I'm misunderstanding something about your question.
