Introduction to NIR Analyzer
An NIR Analyzer (Near-Infrared Analyzer) is an advanced analytical instrument used to measure the chemical composition of materials quickly and non-destructively. Widely adopted across industries such as pharmaceuticals, agriculture, food & beverages, chemicals, and petrochemicals, NIR analyzers provide real-time, accurate data that improves quality control and process efficiency.
With increasing demand for rapid and reliable analytical solutions, NIR analyzers have become a critical tool for modern industrial and laboratory applications.
What Is an NIR Analyzer?
An NIR Analyzer uses near-infrared spectroscopy to analyze materials by measuring how they absorb light in the near-infrared region (typically 780–2500 nm). The absorption pattern reveals valuable information about moisture, protein, fat, fiber, chemical composition, and other key parameters.
Unlike traditional laboratory methods, NIR analysis requires minimal sample preparation and delivers results within seconds.
How Does an NIR Analyzer Work?
The working principle of an NIR Analyzer involves three key steps:
Light Emission – Near-infrared light is directed onto the sample.
Light Interaction – The sample absorbs and reflects specific wavelengths based on its molecular structure.
Data Interpretation – The reflected light is analyzed using calibration models to determine material composition.
This process allows rapid, repeatable, and non-destructive testing.
