Photometers and spectrophotometers that work in the visible range also are used as detectors in LC [liquid chromatography]. These devices are potentially useful both as general and selective detectors by utilizing well-known color reactions that can be performed with the column effluent and monitored by absorption photometry.

La fotometría de llama se divide en dos categorías: fotometría de llama de emisión y de absorción. [...] La diferencia entre ambas es que mientras la fotometría de emisión se centra en la radiación emitida por la muestra, la fotometría de absorción mide la radiación absorbida por el analito.
