REVEAL Online UV-VIS
Ultraviolet (UV) spectroscopy is capable of accurately measuring low API concentration in most rinse solvents. UV measurements have an advantage over measurements in other wavelength regions, as most solvents do not absorb UV light and therefore do not interfere with the measurement of the trace oncentrations of API expected in the rinse solution.
The Reveal E-Series cleaning verification system utilizes UV light sources of various types and performs real-time measurements to quantify the concentration of API in rinse solutions. The Prozess software allows calibrations of absolute concentrations to be easily and exactly developed. The Reveal E-Series can measure over a broad range of concentrations covering the gross cleaning step early in the process and the final measurements at trace concentrations.
