FT-IR Dairy Analyzer
Fourier Transform Infrared (FT-IR) spectroscopy is a highly effective analytical technique used in dairy analysis to assess the composition and quality of dairy products. FT-IR dairy analyzers leverage this technology to provide rapid, accurate, and non-destructive measurements of various parameters in dairy products. Here’s an overview of FT-IR dairy analyzers, including their components, functionality, applications, and benefits:
Key Components of FT-IR Dairy Analyzers
Infrared Light Source :
Purpose : Provides a broad spectrum of infrared light that interacts with the sample.
Types : Common sources include Globar (a silicon carbide rod) or quartz-halogen lamps.
Interferometer
Purpose : Converts the emitted infrared light into an interferogram by creating an interference pattern.
Components : Typically includes a Michelson interferometer with a beamsplitter, fixed mirror, and moving mirror.
Sample Holder
Purpose : Holds the dairy sample in the infrared beam path. Common types include transmission cells, attenuated total reflectance (ATR) crystals, or cuvettes.
Types : For dairy products, ATR accessories are commonly used for their ease of use with solid and semi-solid samples.
Detector
Purpose : Measures the intensity of the transmitted or reflected infrared light after it interacts with the sample.
Types : Common detectors include deuterated triglycine sulfate (DTGS) or mercury cadmium telluride (MCT) detectors.
Data System
Purpose : Processes the interferogram obtained from the interferometer into a spectrum using Fourier transformation.
Software : Provides tools for analyzing and interpreting the FT-IR spectra, including peak identification, quantification, and calibration.
