Array versus Scanning UV Vis Spectrophotometer
A UV Vis spectrophotometer can be classified according to the geometry of the components that build up the optical system for the recording of spectra. The following configurations are generally used in UV Vis spectroscopy:
- Scanning spectrophotometer, usually equipped with a Tungsten-Deuterium lamp
- Array spectrophotometer, usually equipped with a Xenon lamp
Most currently available UV Vis spectrophotometers are equipped either with Tungsten-Deuterium lamps or a Xenon lamp. Spectrophotometer design, in particular the type of lamp and internal optical configuration used, contributes to varying performance characteristics which can influence the efficiency of your lab. What are the differences between each instrument setup? Do you know the benefits of Xenon lamp Spectrophotometers with an array optical configuration?
Xenon versus Tungsten-Deuterium Lamp
Tungsten-Deuterium lamp spectrophotometers are considerably less efficient since two lamps are required to cover the UV Vis spectral range. Moreover, they must continue to operate during the entire instrument up-time. This contributes to shorter life-times and higher instrument maintenance costs.
Xenon lamps, however, cover a similar spectral range with only one lamp. In this case, this type of instrument lamp operates only for the duration of the actual measurement and boasts a minimum lifetime of ten years.
