NIR as a tool for real-time quality determination of Distiller’s Dried Grains

In a prior blog, we shared how NIR online sensors could be used to optimize biofuel processes, starting at the farm, through fuel processing, and into feed applications. In this post we take a closer look at how NIR can be used as a measurement tool for a valuable co-product of the biofuel industry: distiller’s dried grains with solubles (DDGS).   Most ethanol plants in the United States are dry-grind facilities, which use starch...

Tales from the Lab: NIR vs. Dumas for Carbon and Nitrogen Determination

This blog was contributed by Dr. Mark Sullivan, Technical and Application Specialist at BUCHI Corporation. The head of a well-known agricultural testing laboratory recently approached me with an unusual request. This laboratory performs 10’s of thousands of plant tissue analyses annually using the Dumas combustion technique for total nitrogen and carbon (AOAC Official Method 972.43).... Continue Reading →

NIR vs. Kjeldahl

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 scopeVariation in...

BUCHI and CEMSI: Partners in Integration

A rapidly rising consumer food company needed NIR technology to quickly test final product quality in their pilot plant R&D facility. The R&D team wanted an NIR to provide non-contact, process control measurements of food products passing rapidly by on a conveyor belt.  However, being a pilot facility, they desired adjustable and temporary mounting approaches...

Finding the right fit: FT vs Dispersive NIR

The longest continuously running mountain biking series in the United States is hosted in southwest Pennsylvania. Every year, hundreds of locals show up to test themselves in the 5-race series and vie for the title of "local hero." Races each take place at different venues, and each venue has a signature "wrench" to throw at... Continue Reading →
