Abstract
A sampling apparatus is described which contains a cylindrical member containing first and second annular recesses on opposing sides thereof and an opening therethrough. At least one resilient sealing member is disposed in each of the recesses. At least one foraminous support disposed in the cylindrical member over the opening adjacent the first recess. A porous medium is adjacent the foraminous support between the foraminous support and the sealing member. A compression housing is provided which contains first and second housing members for compressing the cylindrical member, sealing members, foraminous support and porous medium between the first and second housing members and a clamping means for compressing the sealing members to form a fluid tight seal. A fluid sample is fed by means of a fluid inlet in the first housing member which inlet is in flow communication with the opening, porous medium and foraminous support. The fluid sample is also in flow communication with a fluid outlet in the second housing member. The clamping means is specially adapted to provide rapid insertion and removal of porous media from the sampling apparatus.
