    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 low-pressure cryogenic fluid sampling system includes a cryogenic sample handle assembly; a transfer and vaporization tubular loop; and a sample vessel. The sample handle assembly connects to a cryogenic storage vessel containing a cryogenic fluid. The tubular loop connects to the cryogenic sample handle assembly. The sample vessel removably connects to the transfer and vaporization tubular loop and accommodates a gaseous sample having a pressure lower than about 200 kPa. A method of collecting a gaseous sample with the sampling system includes purging the sample vessel; actuating the handle to purge and refrigerate the tubular loop; extracting a volume of a cryogenic fluid from the storage vessel into the loop to vaporize the cryogenic fluid and produce a gaseous sample; and transferring the sample from the tubular loop into the sample vessel. The sampling system is safer, maintains stoichiometric quantities in the cryogenic liquid, and reduces cross contamination.

    Abstract: An irrigation management system is disclosed and positionable in-line with an irrigation pipe for monitoring and controlling a flow of fluid therethrough. In at least one embodiment, the system provides an inlet pipe and an opposing outlet pipe in serial fluid communication with the irrigation pipe. At least one fluid control valve is in serial fluid communication between the inlet pipe and outlet pipe for selectively controlling the flow of fluid therebetween. The fluid control valve provides a main valve and a hydraulic actuator for selectively moving the main valve between open and closed positions. The hydraulic actuator is also in serial fluid communication between a pair of actuator valves for moving the hydraulic actuator between open and closed positions. The system also provides at least one sample collection tank configured for temporarily storing a volume of fluid diverted from the irrigation pipe in order to be tested.

    Abstract: A portable hydrocarbon sampling device may include a first housing with a first bore, a valve housing with a second bore coupled to the first housing, and a cross-flow housing with a third bore coupled to the valve housing to form a continuous flow path. The valve housing includes a valve to open and close the second bore. A cross bore may be coupled to the cross-flow housing, and is perpendicular to the third bore. A probe may be disposed within the continuous flow path and in fluid communication with the cross bore. An actuator housing may be coupled to the cross-flow housing. The actuator housing may include an actuator to extend into the probe. A sampling container fluidly may be coupled to the cross bore at end distal to the cross-flow housing. The sampling container may be configured to collect the fluids from the probe.

    Abstract: Described are a fluidic network and a method for aseptic process sampling. The fluidic network includes a sampling valve, filter, manifold and valve control module. A process sample path in the fluidic network includes one or more valve channels and a filter in fluidic communication with the sampling valve. The sampling valve is configurable in a first valve state to receive a process sample into the process sample path from a process source and configurable in a second valve state in which gas and solvent flows may be provided through the process sample path to clean and dry the process sample path to prepare for acquisition of another process sample.
