It is tightly soldered into tungsten carbide and comes with a 10-year warranty. An ergonomic one-finger clamping mechanism simplifies sampling and cleaning, and the 360° rotation gives you plenty of room to maneuver solid and liquid samples.

Modules for gas analysis

Gas analysis grows more important. Bruker offers dedicated gas analyzers, like the OMEGA, but of course, the versatile ALPHA II can also be equipped with dedicated gas sampling modules for transmission IR spectroscopy. Different pathlengths are available addressing the needs of simple quality control of gases up to the detection of lowly concentrated gas components. Heating options are available.


Reflection modules

As the ALPHA II works facing in any direction, so can your reflection measurements. Point the instrument on ceiling murals to analyze ancient paint, or place large polymer work-pieces in front of the instrument. Our reflection modules allow contactless and non-destructive FT-IR analysis of bulky and structured samples. The integrated video camera helps finding the area of interest.



The Multireflection-ATR is a special tool for the analysis of pastes, gels and liquids. Its horizontal, multi-reflection ZnSe crystal offers the extra-high light throughput needed for the analysis of low concentrated sample components. Example applications are the analysis of APIs in pharmaceutical formulations or quality control of tar/bitumen. Watch our video to learn more.


This ATR combines cost-efficiency with great performance. It features a large, high-throughput ZnSe crystal that is suitable for most applications that do not involve very hard or acidic samples. A Germanium ATR crystal is also available (e.g. for the analysis of black polymers or surface sensitivie FT-IR). Both are easy to apply, convenient to clean and analyze solids or liquids.
