Analyzing moisture, and how much of it, is critical to the performance of petroleum products, as well as infrastructure and product integrity. For example, moisture in petrochemical feedstock can cause pipelines and valves to freeze, as well as poison some catalysts. One popular method used to analyze for moisture is Karl Fischer Titration (KFT). KFT has a wide dynamic range but has difficulty in measuring relatively low amounts of moisture. In addition, there are the well-known problems of side reactions and known interferences.
An alternative method combines Shimadzu’s proprietary Barrier Discharge Ionization Detector (BID) with MilliporeSigma’s* moisture analysis column “Watercol”. This combination separates and measures the moisture in a formulation of feedstock and provides sensitive and accurate results with measurements made down to a ppm level of moisture detection without any interferen
