Abstract
An apparatus for corring aqueous surfactant composition and sampling moisture content wherein the apparatus includes a device for delivering composition to a main collection port; a device for coring the composition in the main collection port to form a sample; a device for delivering the sample into an NMR sensor area; a device for measuring moisture level of the sample in the NMR sensor area; and a device for extracting the sample from the NMR sensor area or returning the sample to a main collection port which includes a cross feed piston assembly.
