ASTM D4006 Water In Crude Oil By Distillation
The sample is heated under reflux conditions with a water immiscible solvent which co-distills with the water in the sample. Condensed solvent and water are continuously separated in a trap—the water settles in the graduated section of the trap, and the solvent returns to the distillation flask

Coulometric Karl-Fischer Titration
Disposable vials can be used to take samples for heating vaporization, which is for standard weight solid or quasi-solid samples, such as: plastic particles, toner, inorganic salts, battery separators, liquid crystals, coatings, food, pharmaceuticals, etc. Working principle: The water in the sample is vaporized through the heater, and the water is carried into the reaction bottle by high-purity nitrogen as the carrier gas to participate in the Karl Fischer reaction, so as to obtain the water co

ASTM E203 Volumetric Karl Fischer Titrator
although the volumetric KF titration can determine low levels of water，it is generally accepted that coumometric KF titrations are more accurate for routine determination of very low levels of water. as a general rule, if samples routinely contain water concentrations of 500Mg/kg or less,the coumometric tech should be considered.

ASTM D1796 Water And Sediment In Fuel Oils By The Centrifuge Method
The water and sediment content of fuel oil is significant because it can cause corrosion of equipment and problems in processing. A determination of water and sediment content is required to measure accurately net volumes of actual fuel oil in sales, taxation, exchanges, and custody transfers.
