Abstract
The rate of destruction of thiochrome solutions, obtained from thiamine hydrochloride, when exposed to direct sunlight, shade, dim daylight, artificial light, and various monochromatic light sources has been determined. Direct sunlight, light above 600 foot-candles from an incandescent bulb, ultraviolet light, and monochromatic light sources in the short wave-length region all cause destruction of thiochrome solutions in a short time. Dim daylight not higher than 10 foot-candles is not detrimental to thiochrome for a reasonable length of time. Similarly, light from monochromatic sources in the green region (485 mμ) and above causes no destruction.
