Centrifugation. Centrifugation is a process that uses centrifugal force to separate mixtures of particles of varying masses or densities suspended in a liquid. When a vessel (typically a tube or bottle) containing a mixture of proteins or other particulate matter, such as bacterial cells, is rotated at high speeds, the inertia of each particle yields a force in the direction of the particle's ...

This involves the soaking of the loaded carbon in a 3% HCL solution in order to remove impurities such as calcium, copper and magnesium which can impede both the elution step and the later adsorption of gold onto the carbon after it has been returned to the CIP circuit. Acid washing of carbon is in fact used as a temporary …

The Elution and Goldroom plant is the final step in the gold process flowsheet, where the gold cyanide complex is desorbed from the activated carbon, recovered as a metal in the electrowinning cells, and refined to doré gold bars in the gold room. The activated carbon is regenerated for reuse in the cyanide leaching section.

The salt concentration of the elution buffer in most plasmid purification kits will cause the sample to conduct electricity and kill the cells. If the DNA sample was eluted in 1X elution buffer or the salt concentration is unknown, the sample can easily be desalted using a PCR clean-up kit, such as the E.Z.N.A. Omega Bio-tek Cycle Pure Kit.

deposits on convection surfaces (that could have been easily removed as they formed using a 'soot blower') can become 'sintered', or melted, into glass-like masses known as 'enamel'. Any type of tube fouling acts as an insulator between the flue gas and convection surface, reducing the efficiency of the boiler or heater.
