How does a uv spectrophotometer work
WebNanoDrop spectrophotometers work on the principle of ultraviolet-visible spectrum (UV-Vis) absorbance. Nucleic acids absorb light with a peak at 260 nm. Purified proteins absorb light at a peak of 280 nm, while peptides and proteins that lack tryptophan and tyrosine residues absorb at a peak of 205 nm. WebFeb 1, 2024 · A spectrophotometer is an apparatus that can be used to identify the constituent elements of a material. Spectrophotometer uses the principle of interaction between the light spectrum that has a certain frequency with the material so that it can be measured the transmittance or absorbance of the sample as a function of concentration.
