What is Slope Spectroscopy?
A Unique and Patented Variable Pathlength Technology (VPT)
Providing a more efficient method for analyzing at-line and in-line processes, slope spectroscopy is a UV-based technology that serves as an alternative to the Beer-Lambert Law that focuses on pathlength as the variable that determines concentration.
