Very long optical path length can be vsible with capillary cell, allowing measurements of samples with very low optical densities. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. Summary [ edit ] Description Schematic espectroscopia uv visible UV- visible spectrophotometer.
