Test Color of Pharmaceutical Powders

The colors of pharmaceutical powders, such as sorbitol, microcrystalline cellulose or dibasic calcium phosphate anhydrous, are often measured as an incoming QC check to ensure lot-to-lot consistency. The preferred method for measuring powders is to use a Directional 45°/0° reflectance geometry for its ability to measure color the way the human eye sees color. This is the geometry that is recommended by HunterLab for color measurement of opaque materials that will be viewed by the customer.
