The schematic of the HPLC instrument ordinarily features a degasser, sampler, pumps, in addition to a detector. The sampler provides the sample mixture to the cellular phase stream which carries it into the column. The pumps supply the desired flow and composition in the cell period with the column. The detector generates a sign proportional to the amount of sample ingredient emerging from the column, for this reason making it possible for for quantitative analysis in the sample components.

A detector is required to begin to see the separated compound bands since they elute in the HPLC column [most compounds haven't any coloration, so we are not able to see them with our eyes]. The mobile stage exits the detector and can be sent to waste, or gathered, as desired. In the event the cell section contains a divided compound band, HPLC provides the ability to collect this fraction of the eluate that contains that purified compound for further examine. This is called preparative chromatography [talked about during the section on HPLC Scale].
