Elution order in gas–liquid chromatography depends on two factors: the boiling point of the solutes, and the interaction between the solutes and the stationary phase. If a mixture's components have significantly different boiling points, then the choice of stationary phase is less critical. If two solutes have similar boiling points, however, then a separation is possible only if …

High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.

This 'loaded' carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with superheated water. The washed solution, called pregnant eluate, is passed to the electrowinning circuit (7). The remaining barren carbon is reactivated by acid washing and kilning and returned to the adsorption tanks (8). Precious metals recovery. The pregnant eluate (1) is …

 · The gold can be hand picked, or carefully panned to purity, or better still the final concentrate sent to a lab for Total Fusion assay to give the grams of gold present. The oversize rock is then screened on a 15mm screen by hand and the -15mm is fed to a GoldJigga hand jig to recover any nuggets. The +15mm can be inspected visually for any large pieces of gold, but …

The equipment used for gas chromatography generally consists of an injection port at one end of a metal column packed with substrate material and a detector at the other end of the column. A carrier gas propels the sample down the column. The technician uses flow meters and pressure gauges to maintain a constant gas flow. A gas that does not react with the sample or column is …
