Abstract
A filtration system for a soil analysis device and methods of pressure filtration and automated cleaning are disclosed for generating filtrate used in measuring characteristics of a soil sample and preparing the filtration system for repeated measurements. A mixing chamber combines a soil sample and an extractant into a liquid mixture. The filtration system receives and pressure filters the liquid mixture to quickly generate filtrate used to measure characteristics of the sample. The filtrate is passed to a measurement cell for analysis. Once the analysis is complete, the filtration system performs a cleaning process in preparation to receive a subsequent liquid mixture from another soil sample.
