Answer:D
Which of the following cannot be done to reduce ripple in High-pressure liquid chromatography?
A. Using bellows B. Using restrictors C. Using long nylon tube between pump and column D. Avoiding the use of solvent pump
Explanation: Solvent pumps have to be used to reduce pulses in the solvent flow. When there is a pulsed flow, the efficiency of column decreases.
