Fluorescent indicators
UV indicators with efficient radiation for short-wave as well as long-wave UV ranges
UV :
manganese activated zinc silicate with absorptionmaximumat 254 nm; green fluorescence; relatively
254
susceptible towards acids; thus its fluorescence can be completely quenched by acidic solvents
Uv :
inorganic fluorescent pigment with absorptionmaximumat 366 nm; blue fluorescence
