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.
- High quality optical components ensure reliable analytical data with low stray light achieved using very low noise electronic circuits.
- Deuterium and tungsten light sources deliver superior stability across the full wavelength range. Both types of lamp have self timers and are inexpensive and easy to replace when required.
- The monochromator is completely sealed and the optical surfaces can be easily cleaned to maintain optimum reflectivity over the lifetime of the instrument.
- A maintenance free high resolution direct stepper drive positions the grating precisely, which ensures reproducible wavelength scanning at different scan speeds, thus negating any wavelength peak shift.
- The spectrophotometer shell is made from an environmentally friendly non corrosive material and a simple retaining mechanism on the base allows easy access for air filter changes and routine maintenance.
