Compact FT-IR Spectrometer ALPHA II

Robust FT-IR Analysis for any Application

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.

Design Follows Application

The QuickSnap^TM sampling modules for the ALPHA II offer full sampling flexibility. They allow the analysis of almost any kind of sample (e.g. solids, liquids or gases) each with perfectly matched instrument configuration.

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

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. Alternatively the ALPHA II can also be operated with an external PC.

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 RockSolid^TM 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 unknown samples as a common requirement in failure analysis, competition analysis, and forensics is extremely simple with the ALPHA II.

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

QuickSnap™ FT-IR Sampling Modules

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

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 II'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.

Multireflection-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.

Eco-ATR

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.

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.

External reflection modules

Dedicated reflection modules allow contactless and non-destructive FTIR 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 II 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.

Applications of ALPHA II

The ALPHA II provides an optimal instrument design for almost each sample and therefore is greatly suitable for a large variety of applications.

One of the most important applications of the ALPHA II is quality control in various industries. Here the FT-IR spectroscopic analysis is predominantly utilized to verify the identity and specifications of raw materials and products. Additionally the ALPHA II allows the identification of unknown samples. This is particularly valuable for an effective failure analysis, e.g. when examining a contamination which caused a product defect.

In criminalistics the possibility to determine unknown substances is applied to identify drugs and also trace evidence.

The availability of liquid cells and various ATR options for the ALPHA II allow performing quantitative analysis with always the optimal measurement conditions for the respective sample type. There are dedicated ALPHA II analyzers with internal calibrations available which perform the quantitative analysis of quality-related parameters in wine and the determination of FAME in diesel.

Due to its compact design and its intuitive usability the ALPHA II also is predestined to be used for teaching.

Furthermore 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 can measure art objects on-site and contactless. The gathered information helps in art conservation.
