Calibration of UV-VIS Spectrophotometer

European Pharmacopoeia EP Chapter 2. HPLC and PAT are both more dynamic and system-specific techniques than basic spectrophotometry, with more variables to consider, so, for reasons of simplicity, this article covers the new regulations only in so far as they apply to basic spectrophotometry. The new Edition introduces some new approaches to instrument qualification and suggests new reference materials for qualification measurements. The significant changes to the standard, and their practical implications for instrument users are discussed below. This topic was largely absent from the previous Edition 9. What is to be done if these fixed parameters do not yield a suitable signal-to-noise or linearity is not explained. Requirements for the optical quality of cells have been revised.

Home Calibration Quality Control. Ankur Choudhary Print Question Forum 1 comment. Ensure that the connections of the spectrometer are proper. Measure the absorbance of potassium dichromate solution at the wavelengths given below.

This procedure is very easy when you have the right tools to work with. Photometric accuracy confirms that the absorption data is correct at selected wavelengths. Since all spectrophotometers are different, for example some only work in the VIS range, the wavelengths that need to be tested will be found in your spectrophotometers owner manual. If the data does not match there are some troubleshooting tips to help you out. The NIST calibration filter may need cleaning or re-calibration. In this How to Calibrate a spectrophotometer we only focused on photometric accuracy, but there is much more to cover. So stay tuned for the rest of the series!
