AbstractThe spectrophotometer has become the workhorse for high-throughput routine testing for a wide variety of analytes in chemical and biochemical analysis laboratories. It is important for accuracy and reproducibility in measurement that this instrument is correctly set up and calibrated, a task which is facilitated by an understanding of the principles employed. This presentation reviews the principal issues involved: absorbance calibration, wavelength calibration, and checks for both heterochromatic and isochromatic stray light. Methods and materials for making these checks are compared and discussed. © Springer-Verlag 2005.
