Introduction

UV-Vis spectroscopy is a simple, non-destructive method of analyzing samples in solution, in which the samples are placed in a cuvette and their absorbance or transmittance is measured. This analytical technique is in widespread use in a variety of sectors, including environmental science, medicine, food, and chemicals. In order to ensure accurate results by UV-Vis spectroscopy, several procedures must be followed to prepare the analytical equipment before analysis. These procedures are equipment warm-up, parameter setup, and baseline measurement. Furthermore, to ensure that analysis is reliable, UV-Vis spectroscopy equipment must undergo validation to verify its ability to produce accurate data. The European, US, and Japanese pharmacopoeia (EP, USP, and JP) each include test methods with performance criteria that must be met as part of instrument validation. This Application News describes multiple useful features designed into the UV-1900i Plus UV-Vis spectrophotometer that assist the user in achieving accurate and efficient analysis.
