Chapter 30, Problem 30.10QAP
Interpretation Introduction
Interpretation:
The factor that determined the elution order in sedimentation FFF needs to be determined.
Concept introduction:
Sedimentation FFF is a technique for separating particles from the sample placed in the centrifuge wherein
To remove the smallest particles, a carrier liquid is passed through.
