Spectrophotometer is the device used to measure the intensity of electromagnetic energy at each wave

UV-VIS Spectrophotometer 3092 Manufacturer/Supplier India

Spectrophotometry is one of the most useful methods of quantitative analysis in various fields such as Agriculture, Soil, Environmental, Food, Metal, Mining, Petrochemical, Clinical, Pharmaceutical.A spectrophotometer is the device used to measure the intensity of electromagnetic energy at each wavelength of light in a specified region.

 It mainly consists of a light source, a way to focus light onto the sample, a method to collect the light from the sample, a monochromator to separate the light into its component wavelengths and a detector to measure the intensity of light at each wavelength.

At Labindia, we manufacture state-of-the-art Spectrophotometers ranging from fully automatic ones to UV-VIS Spectrophotometers. The spectrometer is a highly flexible, versatile and high-quality instrument that is carefully crafted for the modern laboratory.

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.
