Abstract
UV–Visible spectrophotometers have been used as a tool for chemical analysis over last few decades. The simplicity and ease of operation makes the instrument more reliable and convenient to use, and therefore, they find important application in many fields. In the present case, the performance evaluations of a UV–Visible spectrophotometer has been made for wavelength accuracy, stray light, resolution, photometric accuracy and photometric repeatability using Certified Reference Materials and other complimentary calibrators. The strategy adopted for the performance evaluation/calibration of the spectrophotometer were based on extensive use of different geo-standards of diverse matrices including the candidate geo-standards like Nephelinite, NKT-1, Syenite, CG-2, Limestone, ML-2 and River sediment, sdAR-1 studied recently as a part of 29th, 30th, 30Ath and 31st round of international geo-standards programmes held recently in addition to, employing a set practice of calibration being followed internationally.
