FAQ
Difference between a UV spectrophotometer and a VIS spectrophotometer?
A UV spectrophotometer measures absorbance of light in the ultraviolet range (typically 200-400 nm), while a VIS spectrophotometer measures absorbance of light in the visible range (typically 400-700 nm). The key difference lies in the wavelength range of light they analyze.
What is the principle of UV-vis spectrophotometer?
Using a light source to illuminate a sample with light spanning the UV to visible wavelength range (usually 190 to 900 nm), ultraviolet visible (UV-Vis) spectrophotometers are utilized. The light that the sample absorbs, transmits, or reflects at each wavelength is then measured by the instruments.
Applications of UV-visible spectroscopy?
It has some specific applications include measuring the concentration of substances such as protein, DNA or RNA, bacterial cell formation, and enzymatic reactions.
