Explanation: Flexible bellows or compressible gas passed through tee columns take up some of the pulsation energy which is released to provide smooth pressure without pulsations. Its main purpose is to avoid pulses. 6. Which of the following is not a characteristic of the syringe pump used in high pressure liquid chromatography?
A. Pressure capability is high
B. Maintenance is frequent
C. Limited reservoir capability
D. Slight change of flow rate when extremely high pressure compresses the solvent
