Ultraviolet and Visible Spectroscopy (UV-VIS)
Equipment: Perkin Lambda 950
Working Principle
- Sample absorbs energy from the
highest occupied
energy level to the
lowest unoccupied
energy level
- Measurements can be made in either
transmission or
reflection mode
Technical Information
- Enzyme kinetic monitoring
- Chemical identification
- Dissolution testing for pharmaceuticals
- DNA and protein activity
