  • UV-1800 Spectrophotometer

Shimadzu Scientific Instruments Inc.Request Info
COLUMBIA, Md., Dec. 17, 2007 -- Shimadzu Scientific Instruments has introduced the UV-1800, its latest ultraviolet-visible (UV-VIS) spectrophotometer. The UV-1800 functions as a stand-alone instrument or can be PC-controlled with USB memory while still maintaining the highest level of wavelength resolution in its class (1 nm), according to the company.

UV Probe data-processing software comes standard with the UV-1800 so users can drag and drop data from an optional USB memory stick onto a PC, Shimadzu Scientific said. The USB interface gives users the advantage of macros and graph functions available with commercial spreadsheet software to reduce effort and enhance efficiency. USB memory saves spectral data, quantitation values and measurement parameters. In addition, it saves parameter settings so multiple users can share one instrument.

With the UV-1800, stray light and noise levels are reduced. Shimadzu’s Lo-Ray-Light low-stray light diffraction grating restricts stray light to half that of the UV-1700. A brighter optical system reduces the noise level (at 700 nm) to 25 percent of the previous model.

Multiple modes, including photometric, spectrum, quantitation, kinetics, time-scan, multicomponent quantitation and biomethod, come standard on the UV-1800. The UV-1800 also offers automated security, and enhanced instrument validation and maintenance functions.

“By utilizing the UV-1800, users can start measurements just 30 minutes after installation,” said John Monti, PhD, Shimadzu’s spectroscopy product manager. “Its functional design and many powerful modes, combined with the ease of operation offered by UV Probe, make it simple to install and use directly out of the box.”

The new design includes a 15-percent smaller footprint (45-cm W x 49-cm D) than the UV-1700 for placement close to other equipment, fewer keys that are spaced farther apart for trouble-free operation and three display screens -- parameter settings, progress status and results display -- for clear information and ease of use.

As a wavefront of light passes by an opaque edge or through an opening, secondary weaker wavefronts are generated, apparently originating at that edge. These secondary wavefronts will interfere with the primary wavefront as well as with each other to form various diffraction patterns.  
diffraction grating
A glass substrate carrying a layer of deposited aluminum that has been pressure-ruled with a large number of fine equidistant grooves, using a diamond edge as a tool. Light falling on such a grating is dispersed into a series of spectra on both sides of the incident beam, the angular dispersion being inversely proportional to the line spacing. By proper shaping of the diamond edge, however, the grooves can be formed in such a way as to concentrate most of the energy into a single spectral...
Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
Pertaining to the measurement of the intensity of light.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
