Water in Solvents

From Guided Wave, Inc.
 

 

The measurement of low levels of water in hydrocarbon solvents is critical to many chemical processes. This note discusses the measurement of the water concentration in using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time mode for continuous process monitoring, or as a laboratory procedure. In either case the NIR technique saves time and money through rapid non-destructive analysis. NIR also offers the benefit of increased safety over traditional methods.
