Abstract
Described are a fluidic network and method for aseptic sampling from a process source. The fluidic network includes a valve that isolates the valve port that receives the process sample from all other valve ports except when the process sample flows through the valve. The fluidic network further includes a sample treatment module having a filter element and a sample preparation element to prepare the process sample for analysis. A positive displacement pump operates to draw the process sample into the fluidic network and to push a portion of the acquired process sample through the sample treatment module before dispensing the treated process sample from the fluidic network. Process sample remaining in a process sample supply line leading from the process source to the process inlet port may be pushed back to the process source via a gas flow to limit the acquired process sample volume.
