Abstract: A method of and system for determining the total magnetic content of a fluid sample introduced within at least one coil. A sample withdrawal event time is determined and, at the sample withdrawal event time, the response of the at least one coil is analyzed in two zones, a first zone before the fluid sample withdrawal event time and a second zone after the fluid sample withdrawal event time. The total magnetic content of the fluid is calculated based on the difference in the response of the at least one coil in the first and second zones at the fluid sample withdrawal event time.

Abstract: An integrated, portable sample analysis system and method. A viscometer subsystem receives a first portion of a sample. A spectrometer subsystem receives a second portion of the sample. A syringe pump subsystem receives a third portion of the sample and is configured to urge the third portion of the sample through a filter which collects particles in the sample thereon. An x-ray analysis subsystem is configured to x-ray the particles. The x-ray analysis subsystem also receives a fourth portion of the sample in order to determine the composition of any dissolved material in the sample. A processing subsystem provides a report concerning the sample and its viscosity, physical properties, particulate count and size distribution, and the composition of particulate and dissolved elements in the sample.

Abstract: A particle counter and classification system including an imaging subsystem configured to determine the size and morphology of particles above a predetermined size in a fluid in a sample cell. A first stage magnetometer sensor subsystem is tuned to detect and determine the size of ferrous and/or conducting particles. An optional second stage magnetometer sensor subsystem is tuned to detect the overall ferrous particle content of the fluid.

A second opposing plate has a surface spaced from the rail by a predefined gap of constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail. The kinematic viscosity of the fluid is determined as a function of the predetermined gap and the time it takes the fluid to flow along the rail.
