Abstract
Composite sample storage and measurement system having a divided vessel for receiving samples, the first part of which stores the samples received, and a second part of which, isolated by a flexible membrane, contains a standard fluid which is displaced to a reservoir to determine the weight of standard fluid displaced, and therefore, the volume of sample received. The reservoir, the flexible line from vessel to reservoir and the vessel are maintained under superatmospheric pressure to assure sample integrity.
