Oct 22, 2014 · This document provides an overview of spectrophotometry, including basic concepts, instrumentation, and applications. It describes how spectrophotometers work by isolating specific wavelengths of light and measuring their absorption by a sample.
Apr 15, 2009 · A spectrophotometer uses light to measure the concentration of solutes in solution. It works by passing light through a sample in a cuvette and measuring the amount of light absorbed. The main components are a light source, monochromator to separate wavelengths, sample cuvette, detector, and display.
