Abstract
A system can include a sampler assembly configured to collect a viscous sample at a first location. In implementations, the viscous sample includes concentrated sulfuric acid (e.g., greater than about 75% H2SO4). The system can also include a valve coupled with the sampler assembly for receiving the viscous sample. The valve is configured to couple with a source of a diluent and a sample transfer line. The system further includes a pump coupled with the valve for injecting the diluent into the sample transfer line along with the viscous sample to dilute the viscous sample and transport the diluted sample to a second location remote from the first location via the sample transfer line. In implementations, the sample transfer line is at least approximately two meters in length.
