Abstract: A sample handling system receives a downhole sample. The sample handle system conditions the sample using a separator and filters to allow discharge of unwanted liquids and particulates prior to flowing the sample to one or more analyzers. Separating the moisture and particulates from the sample improves the operation of the components of the sample handling system, for example, by eliminating unwanted condensate or moisture. A coalescing filter, for example, may protect a proportional valve by removing unwanted particulates and liquids from the sample. Additionally, main components of the sample handling system are accessible from a front of a housing to allow for ease of repair and replacement.

Abstract: Methods, apparatuses, and systems related to gas detection are provided. For example, an example apparatus for gas detection in an air duct component that receives a gas flow associated with gaseous substance is provided. The example apparatus includes a suspension connector component and a gas detection component. The suspension connector component includes a first end that is connected to a gas detection component so that the gas detection component is suspended within the air duct component. The gas detection component includes an asymmetrical outer housing so that the gas flow causes a randomized motion of the gas detection component within the air duct component.

Abstract: A device for measuring the dust content of an air stream includes a supply line having an inlet opening for supplying the air stream toward a measuring chamber for measuring the dust content. An adjustable flow rate pump is configured for suctioning the air stream toward the measuring chamber. A first measuring system is configured for measuring the velocity, temperature, pressure, and moisture content of the air stream at the inlet opening. A second measuring system is configured for measuring the flow rate, temperature, pressure, and moisture content of the air stream in the measuring chamber. A third measuring system is configured for measuring the dust content in the measuring chamber.

Abstract: Systems and methods are described for isolating a sample at a valve prior to introduction to an analysis system, such as sample analysis via ICP-MS. A system embodiment can include, but is not limited to, a valve system including a first valve in fluid communication with a sample reservoir and a second valve configured to permit and block access of a vacuum source to the first valve; a sensor system configured to detect presence or absence of a fluid at the first valve; and a controller configured to control operation of the second valve to block access of the vacuum source to the first valve upon detection of the fluid at the first valve to isolate the fluid within the sample reservoir.

Abstract: A rotary dosing device for use in analytical instrumentation quickly transfers a sequence of precise molar quantities of gas from a primary stream into a secondary stream. The device has a rotating chamber with dosing ports that cycle through three states: fill, equilibrate, and transfer. The device cycles in an overlapping manner such that as one dose volume fills with gas from the primary stream, another equilibrates at a known pressure and temperature, and another transfers its contents to the secondary stream. The device initiates its operation so that the first transfer in a sequence is a properly filled and equilibrated dose from the primary stream. Rather than cycling a single dose volume through the three states multiple times, the overlapping operation of the rotary doser enables multiple precise molar quantities of gas to be transferred in one-third the time.
