Summary of "Investigating the fragmentation pathways of β-naphthol pigments by Liquid Chromatography - Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometry."

Today, β-naphthol pigments are amongst the largest and most widely used classes of synthetic organic pigments. Their application fields range from textile, food and beverages, printing inks, plastics, to paint formulations. Most of the research dealing with their study by mass spectrometry focuses on developing sensitive methods for their quantification, or their removal from industrial wastewater. Their qualitative recognition in formulations whose composition is undisclosed by the manufactures has not been tackled yet.

Medical and Biotech [MESH] Definitions

Hydrolytic enzyme activity used as a histocytochemical test for the presence of esterases in tissue. Substrate used is 3-hydroxy-4'-nitro-2-naphthanilide chloroacetate (naphthol AS-D).

Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed)

Chromatographic techniques in which the mobile phase is a liquid.

Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed.
