Figure F1. Schematic of an OsmoSampler. The system consists of an osmotic pump and a sample coil. The pump creates a pressure differential and flow across the semipermeable membranes that draw the fluid to be sampled into the sampling coil, which is initially filled with distilled water. The sample tubing consists of Teflon or copper for ion and gas samples, respectively.
