The FTIR spectrometer ALPHA II combines outstanding quality with a small footprint and sets a benchmark in terms of user convenience. With the integrated panel PC and the touch-based operation, FTIR spectroscopy has never been easier.

Intuitive & Integrated

The ALPHA II features a new way to operate an FTIR spectrometer. With the integrated panel PC and the dedicated OPUS-TOUCH user interface it takes only three touches for measurement, evaluation and report generation. OPUS-TOUCH is very intuitive and guides you conveniently through the measurement and evaluation process.

Enhanced Performance

The ALPHA II represents the enhanced follow-up model of the very successful ALPHA spectrometer. Due to technical innovations such as advanced stabilization of source and detector it provides several improvements like higher sensitivity, higher spectral resolution, extended spectral range and higher robustness against changes in ambient temperature.

The ALPHA II includes a durable diode laser operated with patented technology to achieve a very high wavenumber accuracy. The well-proven RockSolidTM interferometer accomplishes consistent high-quality results with outstanding stability.

Efficiency in Routine Analysis

The ALPHA II offers all the capabilities needed for efficient routine analysis. It is ideally suited for quality control tasks like incoming goods inspection or the testing of intermediate and final products.

The identification of unkown samples as a common requirement in failure analysis, competition analysis, and forensics is extremly simple with the ALPHA II.

The ALPHA II is further very suitable for quantitative analysis providing optimal measurement conditions for all types of samples.

User-replaceable QuickSnap™ sampling modules allow the analysis of almost any kind of sample (e.g. solids, liquids or gases).

Platinum ATR
It’s the high-performance ATR accessory for any application. It features a monolithic diamond crystal that withstands very hard or corrosive materials. 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.

Universal sampling module
As the name suggests, this is a truly universal sampling module for all kinds of samples: solids, liquids and gases. It offers a transmission sample compartment with a 2×3″ standard sample holder and also accommodates a variety of liquid and gas cells. Example applications are the measurement of KBr pellets, quantification of components in liquids and the quality control of polymer films/foils.

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.

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.

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.

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is a special IR sampling technique. Our DRIFT module was designed for easy sampling and high spectral data quality. This results in an unmatched time-per-analysis for FTIR diffuse reflection measurements of a variety of solid samples: powders, inorganic material, gemstones, papers, textiles and others.

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. It is easy to apply, convenient to clean and analyzes solids or liquids. Watch our video featuring the Eco-ATR.


Bruker decided to design their software with the needs of pharmaceutical companies in mind. Therefore, OPUS and OPUS Touch follow the ALCOA+ principle and are 100% compliant with all major pharmacopoeias and of course 21 CFR part 11. Whether locally or on a server, the ALPHA II ensures data integrity and security.

The ALPHA II is intensively used in the polymer industry. The ALPHA II inspects incoming raw materials, test finished products and investigate coated surfaces. One of the biggest user benefits, are Bruker’s dedicated, up-to-date and ready-to-use methods to identify and characterize recently introduced polymers and fillers.

Industrial Manufacturing & Automotive
Infrared spectroscopy is a decisive tool in industrial applications, whether automated and in-line or manual and off-line. The ALPHA II is used to investigate coatings, used oils, finished products and much more.

The ALPHA II is the most modern approach to FT-IR spectroscopy. Its optional touch-PC gets students interested and quickly involved with science. Its rugged, maintenance-free lets it withstand even the toughest chemistry teaching labs.

Several accessories and toolkits are available to turn the ALPHA II into a quantification power house. Check water in oil, API concentrations, the amount of deuterium oxide in H2O or even the residual ammonia in parquet flooring. Multiple quantification methods facilitate reporting and documentation of results.

Forensic Drug Analysis
The TICTAC spectral library for drug analysis contains traditional as well as newly introduced drugs and illegal substances. All spectra in this library and its updates were recorded with ALPHA II to ensure high-spectral quality. Because the ALPHA II can be quickly moved between operation sites, it is a great tool for governmental institutions like police, border control, or those deal that with illegal substances.

Artefacts & Jewellery
Historical works of art and jewellery have one thing in common: both are precious. The ALPHA II is applied in the restoration of historical paintings, buildings and artwork, and is also an affordable tool for the identification and type classification of diamonds and other gemstones.

One of the many environmental applications is the analysis of microplastics. Particles >500 µm are placed onto the ALPHA II, and a special “high pressure” accessory guarantees spectral quality. Additionally, the ALPHA II is also used to analyze and classify soils as well as other environmental pollutants.
