What is Variable Pathlength Technology?
A different approach to concentration measurement
Variable Pathlength Technology (VPT) is UV-based technology that offers efficient analysis methods for both at-line and in-line concentration measurement processes
- VPT can omit dilution, estimation, and all manual calculations
- The patented Slope Spectroscopy method provides increased accuracy, high repeatability, and easier implementation
- VPT can scale down a seven-step process to two key elements: Measure and Report
- The VPT method efficiently receives multiple linear data points in just under two minutes

How is Variable Pathlength Technology different from traditional UV-Vis Spectroscopy?
Traditionally UV-Visible analysis relies on a fixed pathlength at a single datapoint. This requires sample dilution that can vary from analyst to analyst, introducing variability. UV-based Variable Pathlength Technology (VPT) incorporates the Beer-Lambert law into the Slope Spectroscopy Method, where multiple datapoints are acquired due to having pathlength unlocked as a variable.
