Four levels of AgN03 and KBr reagent concentrations between 0.1N and 1.0N were used to study the effect of changing reagent concentration on the grain size dispersity of a primitive AgBr double-jet emulsion. The emulsions were precipitated in a continuous flow crystalizer at a constant pAg of 8.5 within the crystalizer. Emulsion samples were collected at 5 minute intervals during the make from the crystalizer and used to obtain grain size frequency distribution data. Through the use of multivariate analysis of variance, it was concluded with 95% confidence that AgNOo and KBr reagent concentrations ranging from 0.1N to 1 .ON do not effect the grain size dispersity of a double-jet emulsion precipitated in a continuous flow crystalizer.
