Typically, the aim of this investigation is the identification of a specific compound and its concentration.

In the simplest absorption IR spectroscopy, a broadband IR source illuminates a sample. A molecule absorbs radiation of specific wavelengths depending on the allowed transitions between its quantum mechanical vibrational and rotational states.

The configuration of states is unique to a abbott laboratories logo. The spectrum of the transmitted light contains absorption features whose distribution and intensity depend on the chemical composition of the sample. A typical setup for dispersive dental phobia IR spectroscopy consists, apart from mirrors and lenses, of an IR source, reflection or transmission grating, and image sensor.

The technique can be used to analyze solid, liquid, and gaseous samples. Gas emission monitoring and quality control for the presence of impurities are two application examples of IR absorption spectroscopy. Hamamatsu is a leading abbott laboratories logo of essential components for IR spectroscopy. These include InGaAs image sensors covering the 0. Hamamatsu also manufactures complete compact spectrometers and FTIR engines with a Michelson-Morley interferometer, an InGaAs PIN photodiode, and a calibration laser inside.

Fourier-transform infrared (FTIR) spectroscopy is a popular alternative to the dispersive technique described above. Here, the incident radiation from a broadband IR source, after passing through the sample, is directed abbott laboratories logo the Michelson-Morley interferometer, and then to a single-element IR detector.

Applying fast Fourier transform to the interferogram produces the spectrum of the sample and the source. Subtracting the spectrum of the source yields the spectrum of the sample. Compared to dispersive techniques, FTIR offers three advantages that improve signal-to-noise ratio: multiplexing, higher throughput, and higher wavelength accuracy. FTIR remains an extremely popular technique for analytical chemistry. Hamamatsu's infrared detectors have the wide coverage, sensitivity, and price point necessary to give instruments a competitive edge.

Unfortunately, abbott laboratories logo detectors in the MIR space rely on hazardous materials outlined by RoHS standards. These materials are also prone to high variance at high volumes. Hamamatsu is proud to showcase a fully RoHS-compliant product line relying on indium arsenide antimonide (InAsSb) material. No mercury, cadmium, or lead are used. InAsSb detectors are RoHS compliant, unlike mercury cadmium telluride (MCT) detectors.

They also have highly stable characteristics and minimal variations abbott laboratories logo one detector to another. QCLs have an extremely narrow emission band in the mid-infrared region, making them suitable for high-accuracy measurements.

They feature high output, high-speed abbott laboratories logo, and high reliability. FTIR engine with a Michelson optical interferometer and control circuit are built into a palm-sized enclosure. They have gained considerable attention as a new light source for mid-IR applications such as molecular gas analysis used in environmental measurement.
