Ascorbic acid<\/strong><\/a> (or vitamin C) is one of the most widely used food supplements in the world. In addition to being a notoriously known prevention against scurvy today, it is also an important antioxidant. It is also used in the food industry as a protection for pickled and frozen fruit from browning, in the production of plastics as an additive in polymerization processes or to neutralize iodine in chemical water treatment. This makes it a very important substance, the quality of which needs to be reliably monitored.<\/p>\n

Ascorbic acid is usually mixed with excipients, such as starch, which act as a filler or binder, depending on what is needed. In such mixtures, accurate determination of the ascorbic acid content is a costly and time-consuming operation that requires experienced qualified personnel and a variety of measuring and laboratory equipment. Toxic substances are also often used in such analyzes, which represent an unnecessary burden not only financially but also for the environment.<\/p>\n

One of the most elegant methods of modern analysis is FT-NIR spectroscopy<\/strong><\/a> (near-infrared spectroscopy). It is a fast, simple, accurate and reliable method<\/strong> with which even a non-expert obtains data on the concentration of the test substance in a matter of seconds<\/strong>. It consists of the interaction of electromagnetic radiation (infrared radiation) with a sample, which is absorbed by vibrations that are unique to each molecule. It is therefore non-contact and non-destructive, and thanks to the properties of NIR radiation, it can be measured through a number of packaging materials<\/strong>. In addition, it requires (almost) no sample preparation, so the time and money costs per measurement are minimal.<\/p>\n

\"\"<\/p>\n

With the TQ Analyst<\/strong><\/a> program, you can then easily create a calibration model from the measured spectra, with which each analysis will be a matter of a few seconds.<\/p>\n
