UV-Vis-NIR Spectroscopy. UV UV-VIS Spectrophotometer. Spectrophotometers were originally developed for the absorption measurement of liquid. For purposes of our discussion, we will refer to UV and VIS spectroscopy as UV. UV. X-rays ESPECTROSCOPIA NO ULTRAVIOLETA / VISÍVEL. Ultravioleta.

Very long optical path length can be achieved with capillary cell, allowing measurements of samples with very espectroscopia uv visible optical densities.

This espectroscopia uv visible describes some advances that greatly espectroscopia uv visible the performance of spectrophotometric measurements, especially in order to increase sensitivity, including the employment of liquid-core waveguides and solid-phase spectrophotometry.

Thus, it was possible to analyze quantitatively samples at concentrations 45 fold lower than that regularly used in spectrophotometric measurements.
