A gas sample extraction assembly for controllably accessing gas in a gas sample container includes a coupler body having a coupler bore and a coupler end for engaging the gas sample container; an upper member having an upper member bore; a biasing member disposed between the upper member and the coupler body; and a stem having a first portion coupled to the upper member bore and a second portion disposed in the coupler bore, the stem being movable relative to the coupler body between a first axial position and a second axial position, wherein the biasing member is configured to bias the stem in the first axial position.

A system and method includes receiving at least one instruction from a first computing system to schedule a test of a fluid. An input device is operated for importing at least a quantity of the fluid from a source. A filling device is instructed for filling a vial with a pre-determined amount of the imported fluid. A drawing device is operated for drawing a pre-determined amount of a reagent. The drawing device is activated for adding the pre-determined amount of the reagent to the vial. An output of a photocolorimeter is read. The output indicates a reaction of the pre-determined amount of the imported fluid and the pre-determined amount of the reagent. A result of the test is transmitted to a second computing system.

In one form of the present invention is an apparatus that is capable of periodically diverting at least a portion of a slurry flow from a processing facility and collecting it into a container, such as a bucket. The volume and weight of the collected sample can then be ascertained, and the bulk density of the sample can be derived, and the bulk density data can then be sent via wired or wireless communication means to the processing facility so that they can take steps to alter the characteristics of the slurry flow. In another form, of the present invention, the periodically collected sample from the slurry flow is collected via the apparatus for subsequent analysis in a laboratory.

Systems and methods for automated fluid sampling for tracer testing are described. In one aspect, an automated fluid sampling system includes a pressurized line, such as a production well or an injection well connectively and a fluid separation vessel receiving sample fluids therefrom. The fluid separation vessel includes a plunger and is configured for gravity-mediated phase separation of the sample fluids into a plurality of aqueous, organic and/or gas phase fluid fractions and includes pluralities of inlet and outlet ports for mediating flow of sample fluids therethrough. At least one purging fluid source, such as a gas or liquid, is used for driving the plunger. Sample fluid collection vessels receive phase-separated sample fluids from the fluid separation vessel. Pluralities of fluid lines and solenoid valves operatively link the pressurized line, purging fluid sources, sample fluid collection vessels, and disposal vessel to one another, whereby a controller selectively manages the automated flow of fluids through the various fluid lines.

The invention provides a liquid sampler for the automated sampling of liquids at dedicated pre-determined intervals. The liquid sampler includes a liquid inlet connectable to a liquid circuit containing a liquid to be sampled, a sampling reservoir for collecting a liquid sample, and a sampling pump connected to the liquid inlet, operable to extract a discrete amount of liquid from the liquid inlet and to discharge the discrete amount of liquid into the sampling reservoir.

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 sample liquid-sending apparatus includes a placement portion, a suction mechanism, and a vibrator. A sample container is placed in the placement portion, the sample container containing a suspension of a sample. The suction mechanism includes a nozzle configured to be inserted into the sample container placed in the placement portion, and suctions the sample through the nozzle. The vibrator vibrates the nozzle.
