Microfluidic Cell Separation. Microfluidics is an umbrella category of cell separation methods. 2 Designed to manipulate fluids on a microscopic level to facilitate single-cell isolation, microfluidic technologies are frequently built onto microchips and are commonly known as "lab-on-a-chip" devices. These devices have several advantages ...

Gravity-based separation technologies are the backbone of any coal preparation plant. Gravity separations are informed by float/sink or washability analyses as illustrated in Table 4, showing the distribution of specific gravities in one size fraction of coal.There would be similar tables for each size fraction.

Instead of the SOP being separate from and adjacent to what you're doing, it's actually synonymous with what you're doing." Johnston describes a company that included an SOP show-and-tell in its meetings. Senior managers were each given a separate SOP and four minutes to present a precis on how the SOP applied to the meeting.
