Gz. Zhang et al., DUAL SYSTEM AND DUAL-WAVELENGTH FLUOROMET RIC METHOD AND ITS USE IN PHARMACEUTICAL ANALYSIS, Gaodeng xuexiao huaxue xuebao, 16(1), 1995, pp. 43-46
A new dual system and dual wavelength fluorimetric method has been pro
posed and used to simultaneously determine similar substance phenol an
d resorcinol. The limit of determination is 0.05 mu g/mL and its allow
able concentration proportion is 1 : 10 to 10 : 1, This method has bee
n used in analogous medicament with satisfactory results.
