Apparatus for precisely controlled dilution of fluid samples |
| abstract |
Concentrated fluid samples, such as flue gas samples, are diluted with high accuracy by precisely controlled diffusion through a permeable membrane. The membrane transversely divides a cylindrical housing into two parts, each part having a cup-shaped core therein with an end wall spaced from the membrane to provide transverse-radial flow passages at opposite sides of the membrane and with a side wall spaced from the side wall of the housing to provide longitudinal flow passages of annular cross-section. Fluid is admitted to each longitudinal passage by means of an enlarged circumferential flow distributing passage and is exhausted from each transverse passage by means of a conduit extending through the end wall of the associated core. Electric heating elements are supported upon the side wall of the housing and are controlled by temperature sensors in the transverse passages adjacent to the permeable membrane. The entire housing is surrounded by insulation so that precise control of the temperature within the housing is possible. |
