An apparatus for measuring a condensation property of a condensable component of a gas sample, in particular a hydrocarbon gas sample. The apparatus comprises a measurement cell 2 including a housing and a measurement member 11 which define, in part, a pressurizable gas chamber containing, when in use, a pressurized gas sample. The measurement member includes a surface which is exposed to the gas sample for measurement. The apparatus further comprises a mounting plate 14 upon which the measurement cell is mounted. A space 32 is created between the measurement member 11 and the mounting plate 14 and a conduit 33 connects the space to the outside of the measurement cell such that if an over-pressure is generated in the chamber, the measurement cell is adapted to fail to allow the over-pressurized gas of the gas chamber to exhaust into the space and to the outside of the cell via the conduit 33. |
