Abstract:
1. A process for measuring a swelling effect of a sample fluid on a solid sample comprising the steps of: (a) providing a sample cell which is detachable from a mating component; (b) filling said sample cell in substantially vertical position at least partially with a sample fluid; (c) confining said solid sample with a rigid sample holder; (d) submerging said solid sample into said sample fluid while said rigid sample holder is allowing a free moving surface of said solid sample to move freely and allowing at least a fluid sample contacting surface of said solid sample to contact said sample fluid but prohibiting the remaining surface of said solid sample from movement; (e) applying pressure on top of said sample fluid through a pressure port; (f) and measuring the movement of said free moving surface of said solid sample with a sensor.
