Protein Testing Enters the 21st Century

BIOSCIENCE MEETS FOOD SCIENCE with CEM’s new Sprint™ Rapid Protein Analyzer with iTAG™ Technology.

Protein tagging has been a proven technique utilized in bioscience applications for years. Now, CEM brings this innovation to the food industry. Sprint is a unique analyzer that uses protein tagging to accurately identify and measure protein. Current methods measure nitrogen and calculate the protein. Sprint utilizes an automated protein-tagging technology that attaches to the protein itself for an accurate, direct measurement, so you can be certain your results are not affected by naturally occuring nitrogen, fi llers or contaminants.

Don’t be fooled by fillers
Sprint’s iTAG technology only tags the amino groups found in proteins. Fillers found in some ingredients such as wheat gluten can cause errors. Kjeldahl and Dumas cannot differentiate between nitrogen coming from proteins and nitrogen present in other components.

No method development
Sprint comes pre-programmed with a broad selection of methods ready for use in your laboratory. With its truly innovative software, loading a method and analyzing samples on your Sprint is no more complicated than fi nding a number and calling a friend on your cell phone. Sprint stores hundreds of methods and has a large amount of memory for results, as well.
