Near-infrared spectrometer

A near-infrared spectrometer (NIR spectrometer) is a valuable tool in many different industries, including the food and feed industry, the pharmaceutical industry, and agriculture. When sampling bulk solids, an NIR spectrometer can be used to analyze chemical and physical properties of the sample quickly and without time-consuming sample preparation.

Near-infrared spectroscopy (NIR) is a method that uses near-infrared light (wavelengths between about 800 and 2500 nanometers) to analyze the chemical composition of a sample. This is done by sending the light through the sample and the spectrometer measures how much light is absorbed by the sample. Different chemicals absorb light at different wavelengths, so the resulting absorption spectrum can be used to determine the chemical composition of the sample.

For example, when sampling bulk solids, an NIR spectrometer can be used for rapid analysis of moisture content, protein and fat content, and other important properties in food or feed. It can also be used for quality control in the pharmaceutical industry or to determine the composition of minerals in the mining industry.

An important advantage of NIR spectroscopy is that it enables fast and non-invasive analysis. This means that samples do not need to be destroyed or chemically altered to be analyzed, and that the analysis can often be performed in real time, making it very useful for use in industrial processes.
