Featu r esHighest resolution in its class - 1nm
In addition to achieving a resolution of 1 nm, the highest in its class, by using a monochromator with a Czerny-Turner mounting, the UV-1800 also features a compact, bright optical system. Having a resolution of 1 nm makes it easy to satisfy the standards of wavelength resolution demanded by the European Pharmacopoeia. The UV-1800 also conforms to thespecifications demanded by the Japanese Pharmacopoeia in relation to wavelength accuracy and photometric accuracy. Additionally, hardware validation based on the Japanese Pharmacopoeia can be performed using validation software that is incorporated as a standard feature and an optical filter for wavelength calibration that is calibrated at a bandwidth of 1 nm.

Sp ect rum of Benzene/Ethanol S olution
Benzene exhibits a sharp absorption waveform in a neighborhood of 250 nm. With such a waveform, there is a large difference between the spectra obtained at resolutions of 1 nm and 2 nm. Spectra obtained for benzene/ethanol solution using the UV-1800 and an instrument with a resolution (bandwidth) of 2 nm are shown below. Due to thedifference in resolution, differences in peak intensity of up to 40% can be observed.
Spectrum of Toluene/Hexane Solu tion
Using the ratio of the peak value obtained in a neighborhood of 269 nm for toluene/hexane solution and the valley value obtained in a neighborhood of 266 nm as an indicator of resolution, the European Pharmacopoeia demands a ratio more than 1.5. The ratio for the spectrum shownbelow is 1.94, illustrating the ease with which the UV-1800 satisfies the standards of wavelength resolution demanded by the European Pharmacopoeia.
