Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
“Current methods introduce variability and human error into the mix, so there is no question that existing methods are suboptimal,” says Taylor Reynolds, program marketing manager for Environmental and Ag Bio Testing at MilliporeSigma.
