1. What does a UV spectrophotometer measure?

UV-Vis Spectroscopy (or Spectrophotometry) is a quantitative technique used to measure how much a chemical substance absorbs light. This is done by measuring the intensity of light that passes through optical components with respect to the intensity of light through a reference sample or blank.

2. What are the main components of a UV VIS spectrophotometer?

There are four basic components to a simple single beam UV/Vis spectrophotometer; a light source, a monochromator, a sample, and a detector.

3. What is the difference between UV and visible spectrophotometry?

Molecules having non-bonding electrons can absorb the energy in the form of UV or visible light to excite these electrons to higher molecular orbitals. ... Ultraviolet-Visible Spectroscopy is absorption spectroscopy in the UV and visible portion of the electromagnetic spectrum.

4. Is infrared radiation dangerous?

In general, no -- at least from naturally occurring physical processes. Any form of radiation -- including visible light or radio waves -- could potentially be dangerous if highly concentrated into a narrow beam (that is the principle of lasers) of very high power.

5. What is the function of UV spectrophotometer?

UV / Vis spectrophotometer measures the absorbance of a light when it passes through a sample. The light absorbed is proportional to the quantity of a chemical in the sample.
