With a combination source of light for highly sensitive measurements between 190 and 1,020 nm
The Smartline Diode Array Detector 2800 with a UV/VIS/NIR light source supports a wavelength range of 190 to 1,020 nm. Aside of having an enlarged linearity range, this detector is distinguished by having an outstanding signal to noise ratio. Work with spectra libraries is supported by the detector which makes the inspection of peak purity possible. Maintenance and exchange of the measuring cell is made simple by having direct access to it from the front panel.
