THE NEW 6 8 0 SERIES — sets new standards in Infrared Features include: • Ratio recording for exceptional accuracy and sensitivity • Three slit programs with optimised scan times and digital filtering • Linear absorbance with digital ordinate readout for quantitative measurements • Ordinate expansion keyboard selectable from χ 0.1 to χ 100 • Automatic wavenumber corrector maintains wavenumber accuracy even on the fastest scan speeds 680 SERIES Even though the instruments are exceptionally versatile it has never been easier to obtain good quality spectra than with the 680 series. A wide choice of scanning conditions with digital noise filtering that is optimised automatically makes even difficult samples straightforward. Keyboard selection of instrument settings such as baseline, ordinate expansion, and scan limits improves repeatability and minimises the chance of operator error. Ratio recording ensures accuracy of 0.2%T and guarantees valid results right down to 0%T.
The 680 series sets new standards against which all other infrared spectrometers must now be judged. With microprocessors controlling all instrument functions as well as calculating transmittance or absorbance these instruments represent an important advance in infrared technology.
IR DATA STATION To exploit the full potential of the 680 series the Infrared Data Station is available as a plug in accessory. Software facilities include full data manipulation, interpretative spectral search, and quantitative methods.
