Isbn: 9781390384673 - standard reference materials: glass filters as a standard reference material for spectrophotometry; selection, preparation, certification, use srm 930 (classic reprint) (1 Ergebnisse)

Paperback. Zustand: New. Print on Demand. This book addresses the challenges of obtaining meaningful data from spectrophotometers. Spectrophotometry is a valuable tool for detecting and measuring chemical species across various matrices, yet discrepancies exist in interlaboratory comparisons of spectrophotometric data. The author examines factors that can affect a spectrophotometer's proper functioning and provides means to control these factors, including assessing and controlling long and short term stability, wavelength accuracy, spectral bandpass, stray radiation, and accuracy of the transmittance or absorbance scales. The book also describes the development and use of Standard Reference Materials (SRM) for transmittance in spectrophotometry. The author emphasizes the selection, preparation, certification, and use of SRM 930, a set of three glass filters with nominal transmittances of 10, 20, and 30 percent, which provide a means to control the factors discussed in the book. The insights gained from this work are significant for ensuring reliable and meaningful spectrophotometric data, making this book essential reading for scientists using spectrophotometry in all areas of science.
