Near-Infrared Technology: Promoting Product Quality

in Light

Near-infrared or NIR technology is a clear indication that pure light can be harnessed for a wide variety of uses. The study of spectroscopy is concerned with the interaction between light and matter. In forms an integral part of quality control process in various industries and medical fields. Instruments like the spectrophotometer are essential in making correct assessments regarding certain materials and substances. Without them, we would still be in the dark as to what consumables really contain.

The food you eat and the everyday things you use have most likely undergone spectroscopic analysis before reaching the shelves. This can be thought of as an additional safety procedure that enables quality analysts to determine the composition and suitability of substances used in various products.

When a substance is studied for its spectroscopic properties, it is typically tested for reactions to exposure to light—specifically NIR light. Scientists observe the actual process by which certain materials absorb and reflect light. This method enables them to gain an adequate understanding of the properties of the substance in question as well as its potentials and limitations.

Testing a substance for NIR reflectance is conducted using equipment especially made for spectroscopy, such as a spectrophotometer. Depending on how the wavelengths react to the target substance, scientists can determine the ingredients and their amounts. This is a much easier method of finding out what certain products are actually made of. The results can be printed right away, and any warning labels are issued accordingly.

A complex device like an NIR spectrometer is a useful tool for informing the public about what they eat or use every day. The better the public is informed about a particular product, the better they can prevent any misuse or hazards. Performing such an experiment thus sheds light on any potential issues regarding a product’s safety for consumption.

Industries and institutions have research facilities where they use an NIR spectrophotometer as part of their quality control strategy. Together with intensive research and experimentation, scientists, developers and manufacturers are able to uphold high standards of quality and safety for consumers. NIR technology will continue to benefit countless people for generations to come.
