UV Spectrometer

Ultraviolet (UV) spectrometers measure analytes using light in the UV range (from 10 nm to 400 nm). The key to obtaining light of a specific wavelength is to use the right lamp and common lamps for UV detection include deuterium lamps (which emit in the 190–400 nm range) and xenon lamps (which emit in the 160 to 2,000 nm); a deuterium lamp is often paired with a second lamp, such as a halogen lamp, that detects light in the visible and NIR range. Aside from the light source and wavelength range, other things to keep in mind when purchasing a UV spectrometer are the imaging system, controls, ease-of-use, and sample volume.
