UV-2450/2550

Features

This single monochromator system provides the analyst with the reliability and performance our customers have come to expect in Shimadzu instruments. The low stray light, wide dynamic range, small beam size combination makes this instrument well suited to handle a variety of practical situations.

Software

From small sample volumes to highly absorbing samples, the UV Probe software gives you the power and versatility of an extremely sophisticated system in a package that's easy to learn and use. Additional software enhancements like Kubelka-Munk conversion, area calculations and peak picks make this an instrument for the real world. What's more, it can resolve the triplet peaks in the vapor spectrum of benzene near 250nm with ease.

The UV-2550

An Unparalleled Instrument For Your Demanding Applications

When you can't dilute the sample or reduce the path length, think of the UV-2550. The double blazed grating, double monochromator (DDM) in this instrument is just waiting for those samples. Shimadzu has achieved the world's lowest level of stray light and highest energy throughput with this unique design. By creating two blaze wavelengths (200nm and 600nm), Shimadzu has overcome the energy loss and sensitivity restrictions usually associated with double monochromator instruments. The face of the grating is actually divided into two unique areas for short and long wavelength measurements. The sodium iodide spectra for the double monochromator UV-2550 and a single monochromator instrument described below put this information into practical terms.
