Services on Demand Journal. Long optical path length spectrophotometry in conventional double-beam spectrophotometers: Spectrophotometry is one of the espectrkscopia widespread analytical techniques due to its simplicity, reliability, and low-cost instrumentation for both direct measurements and coupled to other techniques or processes such as chromatography, electrophoresis and flow analysis.

Strategies to increase sensitivity in UV-VIS spectrophotometry
Para tanto, basta que haja disponibilidade em quantidade da amostra que se quer determinar. Espectroscopia uv visible, the application is often limited by sensitivity. We describe the design and tests of a set-up mounted in a conventional double beam spectrophotometer, which allows the determination of optical density of samples confined in a long liquid core waveguide LCW capillary.
