Paperback. Etat : New. Print on Demand. This book presents a study of optical transmittance standards and their use in analytical methods. The author explains the importance of accurate spectrophotometric techniques in assessing the optical characteristics of various materials. They also discuss the development of Standard Reference Materials (SRMs) to ensure precision, accuracy, and comparability of measurements. The author describes the various types of SRMs available for spectrophotometry, including glass filters, liquid standards, and reference cuvettes. They discuss the factors affecting the accuracy of spectrophotometric measurements, such as wavelength accuracy, spectral bandpass, radiation path length, stray radiant energy, and transmittance scale accuracy. The book also provides detailed information on the high-accuracy spectrophotometer constructed at NBS for the certification of these SRMs. This book is a valuable resource for scientists, technicians, and quality control personnel involved in analytical chemistry and spectrophotometry. It provides a comprehensive overview of the subject, from the fundamental principles to the practical applications of spectrophotometric techniques. The author's insights on the accuracy and reliability of spectrophotometric measurements will help readers to improve the quality of their analytical results and ensure the comparability of their data with other laboratories. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781390521658_0
