Recent Advances in Ultraviolet-Visible Spectrophotometry

Abstract

Developments in UV/VIS spectrophotometry during the past decade are critically reviewed. Advances in instrumentation: sample handling, optical systems, detectors, and signal processing are discussed. The application of spectrophotometric detection in hydrodynamic systems is surveyed. Newer types of color systems employing macrocyclic compounds, porphyrines, surfactants, and basic dyes are evaluated. Separate sections are devoted to advances in spectrophotometric determination both of individual elements and organic compounds. Future trends in spectrophotometric analysis are discussed.
