 Fluorescent pigment classification


Fluorescent pigments can be broadly classified into three major categories.
1.Basic fluorescent pigments These pigments are easily dissociated in an acidic solution. Its fluorescentcomponent carries a positive charge. Therefore,it is capable of ion-binding with an acidic group in a biological specimen. In the alkaline solution, it is in a non-dissociated state. 
2.The acidic fluorescent pigment is easily dissociated in an alkaline solution, and its fluorescentcomponent is negatively charged. 
3.Neutral fluorescent pigment is weakly acidic or weakly basic. Fluorescent pigment is an electricallyneutral pigment in fluorescence. The dissociation during dyeing has no practical significance. This pigment is mostly used to display macromolecules.

 Fluorescent pigment classification
Fluorescent pigment Application range
The field of using fluorescent pigments is particularly broad. For example, the identification of mineral oil impurities in mineralogy, the classification of quartz sand in the optical glass industry, the identification of reservoir leaks in hydrogeology, the detection of blood and fine spots in forensic science, inspection in the mechanical industry Metal cracks, the identification of classical art works and products, bacteriology, virology, immunology, oncology, genetics, fiber textile industry and various other professions can be applied to fluorescent technology.
