Abstract
The quantitative potassium bromide disk technique has been investigated and methods have been adopted for its application to some pharmaceuticals. Average deviations from linearity within ±4.0 per cent were obtained with some crystalline compounds. Analyses of pharmaceutical preparations, by hand-grinding or vibrator-grinding methods, resulted in average agreement within ±3 to ±4.5 per cent with ultraviolet spectrophotometric or gravimetric determinations.
