ALPHA II FTIR Spectrometer

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

Intuitive and Integrated

The ALPHA II is available with a new way to run an FTIR spectrometer. With the integrated panel PC and the dedicated OPUS-TOUCH user interface it just takes three touches for measurement, evaluation and then report generation. OPUS-TOUCH is extremely intuitive and guides users conveniently via the measurement and evaluation process.

Enhanced Performance

The ALPHA II represents the improved follow-up model of the extremely successful ALPHA spectrometer. Due to technical innovations such as improved stabilization of source and detector it offers several enhancements like higher spectral resolution, higher sensitivity, extended spectral range and gretaer robustness against changes in ambient temperature.

The ALPHA II is made up of a durable diode laser operated with patented technology in order to achieve extremely high wavenumber accuracy. The well-established RockSolidTM interferometer achieves consistent high-quality results with exceptional stability.

Efficiency in Routine Analysis

The ALPHA II offers all the capabilities required for effectual routine analysis. It is perfectly suited for quality control tasks such as the testing of final and intermediate products or incoming goods inspection.

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

Additionally, the ALPHA II is extremely suitable for quantitative analysis offering optimal measurement conditions for different types of samples.

Design Follows Application

The QuickSnapTM sampling modules for the ALPHA II provide full sampling flexibility. They enable the analysis of almost all kinds of samples (for example, liquids, solids or gases) each with flawlessly matched instrument configuration.

Multiple sampling accessories for attenuated total reflection (ATR), transmission, external and diffuse reflection are available in order to fulfill the needs for many different analytical questions.


The ALPHA II offers an optimal instrument design for almost all samples and therefore is immensely suitable for an extensive variety of applications.

One of the most vital applications of the ALPHA II refers to quality control in different industries. Here, the FT-IR spectroscopic analysis is mainly utilized for verifying the specifications and identity of raw materials and products. Additionally, the ALPHA II permits identification of unknown samples. This is mainly valuable for an efficient failure analysis, for example, when investigating a contamination which brought about a product defect.

In criminalistics, the possibility of determining unknown substances is employed in order to detect drugs and also trace evidence.

The availability of liquid cells and several other ATR options for the ALPHA II permit the performance of quantitative analysis with always the optimal measurement conditions for the respective sample type. Dedicated ALPHA II analyzers with internal calibrations are available and they perform the quantitative analysis of quality-related parameters in wine and also perform the determination of FAME in diesel.

The ALPHA II is predestined to be used for teaching because of its compact design and its intuitive usability.

Additionally, several mobility options provide for the portable use of the ALPHA II. Mounted on a tripod and powered by a battery pack, the ALPHA II is capable of measuring art objects on-site and contactless. The collected information helps in art conservation.
