A sorbent tube apparatus 10 for high-pressure fluid sample analysis, comprising a pressurisable housing 32 having first and second fluid ports 48a, 48b and defining a fluid chamber 34 therein, and a sorbent tube 12 mountable within the pressurisable housing 32, the sorbent tube 12 extending from one of the first and second fluid ports 48a and spaced apart from the other of the first and second fluid ports 48b such that the port is in fluid communication with the fluid chamber 34, thereby enabling pressure equalisation between the sorbent tube 12 and fluid chamber 34. In use, a fluid sample is discharged from the sorbent tube directly in to the fluid chamber of the housing so that difference in pressure between the interior and exterior of the sorbent tube is minimised. A method of analysing high-pressure fluid, an analytic probe apparatus, a further sorbent tube apparatus and method of preventing or limiting damage to a sorbent tube during high-pressure fluid sampling are also provided. |
