The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples.

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

UV and visible spectrometers measure the amount of ultraviolet and visible light transmitted or absorbed by a sample placed in the spectrometer. The wavelength at which a chemical absorbs light is a ...

The monochromator features dual gratings (automatically exchanged): 1200 grooves/mm for the UV/VIS region; 300 grooves/mm for the NIR region. A PMT detector is provided for the UV/VIS region and a ...

A new ultrafast laser platform generates ultra-broadband UV frequency combs that could enhance high-resolution atomic and ...

Pharmaceutical spectroscopy techniques like NMR, mass spectrometry, and UV-Vis play essential roles in pharmacokinetics, ...

In this list, discover how ultraviolet/visible (UV/vis) spectroscopy rises to the challenges of biopharmaceutical development and manufacturing processes. You may have certainly enjoyed an authentic ...

Researchers have developed a new ultrafast laser platform that generates ultra-broadband ultraviolet (UV) frequency combs ...

C/2023 A3 was briefly and barely visible last week in the early morning sky. In the end, most folks were unable to see it as it was very faint and low to the horizon. We will have a much better ...

In May, the strongest solar storm in 21 years set off the aurora borealis and on Thursday night, the stunning colors were visible once again even to the naked eye across much of the United States.

They simulate the full-spectrum range of natural light, and include a balance of the ultraviolet and the visible color regions. UVA (Long Wave) UV systems produce UVA, the near or long wave UV band ...
