A multi-phase sampling collection system includes a three-way four-port valve unit that includes a valve housing having a first port, a second port opposite the first port, and a third port. The valve unit includes an inner valve member that is movably disposed within the valve housing between a plurality of positions. The inner valve member has a main valve body that has a first valve opening, a second valve opening opposite the first valve opening, a third valve opening and a fourth valve opening opposite the third valve opening. The third valve opening is defined by a plurality of orifices for mixing incoming non-homogenous fluid to generate a mixed homogenous fluid and the fourth valve opening has a lesser diameter that the third valve opening for increasing fluid pressure drop, fluid velocity, and fluid turbulence resulting in improved mixing of the non-homogenous fluid that exits through the fourth valve opening.

Interaction of adsorbing chemicals with a downhole tool presents inaccuracies in the adsorbing chemical measurement and analysis. The principles of the present disclosure provide a method and system of sampling fluids including an adsorbing chemical in a subterranean reservoir. One method may include modeling an interaction between the adsorbing chemical and a downhole tool, applying the model to a measurement of the adsorbing chemical, and adjusting the measurement in response to applying the model.

The invention relates to an apparatus for the inline trace analysis of a liquid, preferably of an aqueous process solution, comprising: a housing (1); a micro-channel (2) through which the liquid to be examined is allowed to flow and into which light of a light source (3) is coupled; a detector (4) for light emerging from the micro-channel (2); and a user interface (5) for monitoring and/or operating the apparatus. The micro-channel (2), the detector (4) and/or the user interface (5) are arranged in the housing (1) and/or are integrated into the housing (1), and the housing (1) has a connection (6) for feeding the liquid in the micro-channel (2) and a connection (7) for power supply of the apparatus.

Systems and methods for automatic sampling of a sample for the determination of chemical element concentrations and control of semiconductor processes are described. A system embodiment includes a remote sampling system configured to collect a sample of phosphoric acid at a first location, the remote sampling system including a remote valve having a holding loop coupled thereto; and an analysis system configured for positioning at a second location remote from the first location, the analysis system coupled to the remote valve via a transfer line, the analysis system including an analysis device configured to determine a concentration of one or more components of the sample of phosphoric acid and including a sample pump at the second location configured to introduce the sample from the holding loop into the transfer line for analysis by the analysis device.

Process inserts, assemblies, and related methods for use in monitoring high velocity fluids or supporting instruments that monitor and manage high velocity fluids are disclosed. Exemplary inserts include a head having a cavity for receiving an instrument, a shank, and an integral flange. The shank includes an elongated body having a first end disposed proximate to the head, a free end opposite the first end, and a threaded portion spaced apart from the first and free ends. Exemplary process insert assemblies include a process insert having a shank and a threaded support disposed around the shank. Methods of making and using process inserts are also disclosed. For example, a method of installing a process insert on a container includes inserting the free end of the process insert in the interior volume of a container containing a high velocity fluid.

A system to detect grain loss of a harvester during harvesting operations. The system includes at least two pans magnetically supported on the harvester above a ground surface, by separate electromagnets being electrically isolated from a power source while magnetically supporting the at least two pans. A signal controller generates a release signal when triggered by a user. A signal receiver responsive to the generated release signal electrically connects one of the electromagnets with the power source causing one of the at least two pans to be released to the ground surface while the second electromagnet remains electrically isolated from the power source and magnetically supported on the combine harvester until another release signal is triggered by the user causing the signal receiver to electrically connect the second electromagnet with the power source to release the second pan to the ground surface.
