What Makes NSL Different

NSL can also analyze samples indirectly using oven desorption/vaporization, the preferred technique for certain types of samples such as metal powders. These tests conform to the following ASTM standard test methods:

  • ASTM D6304 Water in Petroleum Products, Lubricating Oils and Additives by Coulometric Karl Fischer Titration (including optional oven desorption/vaporization)
  • ASTM E1064 Water in Organic Liquids by Coulometric Karl Fischer Titration
  • ASTM E203 Water Using Volumetric Karl Fischer Titration
