SPEC RES+ / SPEC RES+ UV

​• Wavelength range: 180-400 nm
​• Optical Resolution: 0.2nm
​• 3648 pixels Toshiba CCD array detector
​• 1800 grooves/mm grating blazed at 250 nm
​• Best solution for high resolution UV
​• LightScan software included

For UV enthusiasts that need really good resolution in that range the SPEC RES+ UV is the perfect choice. Covering the entire UV range with an optical resolution of 0.2 nm. It’s configuration complies a 10 µm slit, a 1800 grooves/mm grating blazed at 250 nm, collecting lens, SMA 905 connector and a Toshiba 3648 pixels CCD array.

This configuration is suitable for high resolution Absorbance where in the Chemistry field it’s possible to test aromatic compounds and solvents. In Biology and Medical areas the purity and type of a nucleic acid is determined by the ratio of Absorbance values, read at 260 and 280 nm. Transmission and Irradiance measurements in application areas such as Physics and Materials are also possible with this spectrometer. Combine it with a Flow Cell FCFPE and LS-DW Light Source to use it as an HPLC detector.

The SPEC RES+ UV spectrometers are coated for high UV sensitivity and extended UV range down to 180 nm.

The spectrum below (left) shows the full spectra using a Mercury lamp with special focus (right) on two very close lines: 312.57 and 313.15 nm. These two lines are normally indistinct but perfectly resolved on this configuration.
