Blue has a wavelength of around 480 nm and will make your sample visible. If your sample is too concentrated you can dissolve it in water.
The ultrapure Anthracene Pure ( ) supplied from CDH INTL is supplied in 1. The reagent contains very low traces of production synthesis impurities and is highly purified by ultra filtration and distillation for the chemical compounds.
Fluorimetric analysis of fluorescent emission of light by is a form of luminescence. The emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation for excitation. Fluorescent controls and calibrators can be supplied to mix with the cells. A fluorimeter is needed to do the analysis of the green, red, blue, yellow, orange, deep red fluorescent dyes.
