Bruker Corporation Alpha ll


Alpha ll

The ALPHA II is a very compact FTIR spectrometer for quick, easy and reliable IR analysis. The design of its hard- and software are highly integrated for an intuitive and convenient operation.     
All spectrometer components are built for continuous availability and a long life time. Bruker’s permanently aligned RockSolidTM interferometer and the reliable diode laser guarantee an accurate and precise data acquisition. Thanks to the CenterGlowTM IR source technology and a temperature controlled detector the ALPHA II provides a constantly high performance. The need for maintenance is minimized and running costs are kept very low as a result of long lasting relevant components like interferometer, IR source and laser. A wide range of QuickSnapTM sampling modules is available for the ALPHA II, providing a perfectly matching measurement setup for a large variety of samples and applications.     
OPUS provides the right software user interface for the most efficient FTIR analysis. From measurement to evaluation to the final analysis report the user is guided through the analytical workflow in just a few steps. Therefore,the ALPHA II is easily operated even by spectroscopic inexperienced personnel. Powerful but easy to use functions for verifying and identifying IR spectra and performing quantitative analysis are included in the software.     
The option to use the ALPHA II with the OPUS-TOUCH software on an integrated touch panel computer makes your daily routine analysis even simpler. Moreover, the footprint of the complete system is reduced to that of a laptop.
