文摘The effects of temperature and wavelength choice on in-situ dissolution test instrument of Cimetidine were studied. Absorbance （A）〈 1.0 is required when using a fiber-optic dissolution test system.

Calibration of Cimetidine solution should be tested at the same temperature （37° C） with the test solution.
