Column Chromatography - Instrumentation - Microbe Notes

Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis.; It is a separation technique in which a mobile phase carrying a mixture is caused to move in contact with a selectively absorbent stationary phase.

Slurry - an overview | ScienceDirect Topics

Slurry supply can use vacuum/pressure or a pump. Both systems supply slurry to the machining system by circulating it in a slurry pipe. It is assumed that the slurry may contact valves, orifices, pipes, vacuum or N 2 gas and stay there while turning over, so action should be taken to supply slurry in a stable manner at all times. Figure 4.9 shows one example of a slurry supply system.
