ABSTRACT:
A refractometric densitometer includes a first packing element and a first gasket disposed at one side of a glass element and a second packing element and a second gasket disposed at the other side of the glass element. A groove for passage of a reference material and a groove for passage of a sample are respectively formed in the first and second packing elements. An inlet pipe and an outlet pipe are formed in the first and second gaskets for passing the reference material or the sample to the grooves. The outlet pipe of the first gasket is connected to the inlet pipe of the second gasket. Multiple reflection is imparted to an incident light from the part of the glass element between the faced surfaces of the glass element contacting the first and second packing elements.
