ALPHA FT-IR Spectrometer

  • About the size of a lab book, the extremely compact FTIR spectrometer ALPHA will play a big part in your daily routine. Plug & play set-up, easy-to-use software, combined with QuickSnap™ sampling modules assure powerful and reliable FTIR analysis you expect from Bruker.


    The ALPHA will save you the much needed bench space in your laboratory. ALPHA's footprint only takes up a 22 cm by 30 cm space (about 8" by 11"). ALPHA is light as well, only weighing about 7 kg (about 13 lbs).

    No sacrifice in performance

    The ALPHA interferometer is based on Bruker Optics` patented RockSolid™ design, which is used in our laboratory and rugged process spectrometers. This means the ALPHA delivers the performance and reproducible results people have come to expect from a Bruker FTIR spectrometer. The ALPHA is also insensitive to vibration, so it can be placed almost anywhere, can be moved, and be immediately operational without any need for alignment. ALPHA delivers excellent sensitivity as well as x-axis reproducibility and stability.

    Practicality for routine analysis

    The ALPHA makes FTIR analysis simpler than it has ever been before. With it's plug-and-play operation, easy to set-up and ease of use, ALPHA brings practicality to FTIR spectroscopy. ALPHA offers all the capabilities you expect to achieve for a routine analysis. The intuitive OPUS/Mentor software interface guides you every step of the way. The software is easy to learn. You will use your time for the FTIR analysis – not for learning the software.

    Flexible sampling

    The ALPHA offers full FTIR sampling flexibility. User exchangeable QuickSnap™ sampling modules allow the analysis of almost any kind of sample (e.g. solids, liquids or gases). Transmission, attenuated total reflection (ATR), external and diffuse reflection FTIR sampling accessories are available.

  • DRIFT.

    The DRIFT module allows to economically analyse a broad variety of solid samples: powders, inorganic material, gem stones, papers, textiles and others. The DRIFT module is designed for easy sampling and high light throughput. This results in an unmatched time-per-analysis for FTIR diffuse reflection measurements.                                                                                                                                                                            


    ATR is an easy to use FTIR sampling method that is ideal for both solids and liquids and does not require any sample preparation. The Eco ATR is a single reflection ATR sampling module with a very attractive cost/performance ratio. It is equipped with a versatile high throughput ZnSe ATR crystal for the analysis of powders, solids, pastes and liquids.                                                                                                                                                                                                 

    External reflection modules

    Dedicated reflection modules allow contactless and non-destructive FT-IR analysis of large samples on top or in front of the spectrometer. Paper or textile Fabrics are simply placed on top of the instrument to be analyzed. Also very large or even immobile samples like metal surfaces of car parts or mural paintings during restoration process can be investigated, by placing the instrument in front of the object. An integrated video camera helps finding the sampling area.

    Modules for gas analysis

     Different dedicated sampling modules with integrated gas cell allow the measurement of gases and gaseous mixtures by transmission IR spectroscopy. The ALPHA sampling module with 7 cm gas cell is characterized by a minimized cell volume that requires little sample amounts and allows fast gas exchange. The module with 4.8 m gas cell provides the sensitivity to detect low concentrations. Heating options prevent condensation of gases in the cell.


    Universal sampling module

     The universal sampling module enables you to analyze all kind of samples: solids, liquids and gases. This transmission sample compartment with its 2x3" standard sample holder can hold a variety of gas cells and liquid cells. Solid samples can be investigated in a standard pellet holder or using a magnetic film holder. Samples with a reflective surface are analyzed with a dedicated accessory for reflection measurements.

    Platinum ATR

     ALPHA's Platinum ATR single reflection diamond ATR module is designed to bring more ease to your routine analysis. The ergonomic one-finger clamp mechanism simplifies the sample positioning. It is easy to clean, as the pressure applicator can be rotated 360° to provide the user with unobstructed access to the sampling area. A variety of sampling options for temperature controlled measurements and liquid flow through analysis complete the versatility of the Platinum ATR.


    The Multireflection-ATR module with horizontal ZnSe ATR crystal is very suitable for the analysis of pastes, gels and liquids. Six internal reflections and an exceptionally high light throughput provide highest ATR measurement sensitivity for the analysis even of low concentrated sample components.
