What is UV-VIS NIR spectrophotometer?

Ultraviolet/Visible/Near Infrared Spectroscopy (UV/VIS/NIR) UV/VIS/NIR spectroscopy is a powerful analytical technique to determine the optical properties (transmittance, reflectance and absorbance) of liquids and solids. UV/VIS/NIR operates in the optical range between 175 nm to 3300 nm.

What is the use of UV-VIS spectrophotometer?

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 a sample with respect to the intensity of light through a reference sample or blank.

What is the difference between a UV spectrophotometer and a VIS spectrophotometer?

There is no difference between UV and visible spectrophotometer because both these names are used for the same analytical instrument. This instrument uses the absorption spectroscopy technique in Ultraviolet and visible spectral region.

How far does UV light travel?

The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm).

Which is the best UV-Vis / NIR spectrophotometer?

UV-Visible/NIR Spectrophotometer UH4150 Model U-4100, the expert in solid-phase spectrophotometry, has advanced even more. Now, Model UH4150 has emerged inheriting the reliability of the U-4100 Spectrophotometer, which boasts the total number of shipments more than 1,500*1 units. *1: Models U-4000 and U-4100 as of October 2012.

What’s the scan speed of a Hitachi UV spectrophotometer?

Higher throughput, compared with the conventional instrument, was achieved and the analysis with the scan speed of 1,200nm/min for the sampling interval of 1 nm is possible. For example, for the wavelength range of the analysis introduced this time, the measurement can be completed in about 2 minutes.

What kind of optical system does Hitachi uh4150 use?

The UH4150 adopts a prism-grating (P-G) double monochromator optical system, continuing the established reputation of the U-4100 optical system. Large changes in light intensity of the S and P polarization are less likely for the prism-grating (P-G) system than for the generally used grating-grating (G-G) system.

What are the wavelengths of ultraviolet light in Nir?

Ultraviolet-Visible-near-IR Spectroscopy (UV-Vis-NIR) Measurements in the ultraviolet/visible region (UV-VIS) cover wavelengths from about 200 nm to 800 nm. The absorption of ultraviolet or visible radiation by a molecule leads to transitions among the electronic energy levels of the molecule.
