Problem- Explain the difference between UV/Vis and Fluorescence spectrophotometry.
a) Which has greater sensitivity?
b) Draw 2 block diagrams to illustrate the differences?
c) Are there sample holders (SH) for each instrument interchangeable?
(can you use SH from UV/HVIS in a fluorometer, and vice versa)
