Explanation: High pressure liquid chromatography can be performed only in columns. This is because application of high pressure in open bed will not be effective. 3. Which of the following is not an advantage of Syringe type pumps used in High pressure liquid chromatography?
A. Independent of viscosity
B. Pulse-less flow
C. High pressure capability
D. Unlimited solvent capacity

A. Independent of viscosity B. Pulse-less flow C. High pressure capability D. Unlimited solvent capacity
Explanation: The limitation of Syringe type pump is that it has limited solvent capacity and is inconvenient when solvents are to be changed. 4. Which of the following is not true about solvent programming which is done in high performance liquid chromatography?
