Abstract
Systems and methods for measuring the moisture and sediment content of a petroleum sample. In one embodiment, a sample to be tested is collected in a field bottle. The sample from the field bottle is then transferred from the field bottle, and into and through a measurement column containing a high-uptake gelling agent, such as a superabsorbent polymer. The sample's moisture is determined by measuring the expanded volume of the high-uptake gelling agent. The measurement column also contains a sediment measurement section having a sediment filter and a sight glass with graduations to measure the sediment content of the sample.
