column chromatography notes examples

Introduction to Medium

Smaller beads or lower porosity in the chromatography media Sample application Buffer pumps are used to pump samples onto the column because the column backpressure is relatively high The plumbing can vary depending on the volume or clarity of the sample Some examples are:
