Pharmaceutical Liquid Color Testing with a Spectrophotometer

The improvements made over the years to measuring liquid color have elevated visual-based methods to a markedly greater reliability level thanks to today’s advanced color measurement process. Where once an array of physical samples had to be prepared manually with differing levels of dilution and then compared against a set of standards via the human visual system, today’s spectrophotometers take the guesswork–and tedious preparation–out of the equation.
