ALPHA II Compact FTIR Spectrometer

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.

 

 The need for maintenance is minimized and running costs are kept very low due to the long life time of the 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.

 

 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.
