Another blog not about NIR? Near-infrared (NIR) spectroscopy is a secondary method. That means that NIR doesn't measure things like fat, protein, moisture, ash, %-polymerization or anything else directly. Instead, we use an acceptable primary method to train our NIR to make those measurements. More details on NIR calibration can be found in this earlier... Continue Reading →
Protein is a critical parameter across the food, beverage, and feed industries. However, the best solution for obtaining protein varies across the production cycle. In this blog, we propose Kjeldahl and near-infrared (NIR) spectroscopy methods for protein determination, with arguments for which technology is the best fit based on factors such as: Application scope Variation...

Why are we talking about Kjeldahl on the NIR blog? This blog has made many mentions to the fact that near-infrared (NIR) spectroscopy is a secondary method. That means that NIR doesn't measure things like moisture, fat, protein, ash, %-polymerization or anything else directly. Instead, we use an acceptable primary method, like Kjeldahl, to produce...

Raman and near-infrared (NIR) spectroscopy are complementary methods, both probing vibrational transitions in molecules. In general, the strong bands in the (N)IR spectrum of a compound correspond to weak bands in the Raman and vice versa. This blog will look at some of the differences between Raman (light-scattering) and NIR (light absorption) methods. Here just... Continue Reading →
Winter felt brutal and eternal, as it always does for someone who doesn't ski or care for hot chocolate, I suppose. What a relief it is to see signs of Spring emerging from my brownish-colored yard and hear birds chirping outside once again. Did you know NIR is quite Spring-y as well. This blog will...

Is there a simple answer? Of course not! When it comes to the debate regarding which infrared spectroscopy reigns superior, near-infrared (NIR) or mid-infrared (IR), the answer should be a reflect the merits of the technology in light of the application of interest. It's like asking whether a knife is better than a spoon. Well,... Continue Reading →
