A system for handling effluent from a film processor. In one embodiment, the germania-silica-based sol-gel monolith can be used to coat surfaces of the inner walls of extraction and chromatographic columns. The latter forms part of a fluid channel, which extends from the inlet to the outlet of the housing. The first processor includes a congestion detection logic to detect congestion of access of the resource based on a consecutive number of negative acknowledgements received in response to the access requests prior to receipt of a positive acknowledgment in response to one of the access requests within a first time period. The invention further provides a method for forming the organic solar cell.
