    Abstract: An exhaust sampling system includes a pre-fill gas source having a pre-fill gas. A sampling conduit is configured to collect exhaust gas and make-up gas. A sample bag is fluidly connected to the sampling conduit and the pre-fill gas source. A controller is programmed to run a test procedure in which a sample of exhaust gas and make-up gas is collected in the sample bag. The controller sends a command that fills the sample bag with pre-fill gas prior to the test procedure. The pre-fill gas remains in the sample bag during the test procedure. In one example, the amount of pre-fill gas is selected to prevent the sample from condensing in the sample bag during the test procedure. In another example, the amount of pre-fill gas is selected to provide a sufficient volume of gases for analysis during the test procedure.

  • Patent number: 7555965
    Abstract: A system for obtaining a representative sample of a natural gas stream, particularly a stream which is at or below its hydrocarbon dew point temperature (H.C.D.P.). The preferred embodiment of the present invention contemplates a sample cylinder having a flexible isolation barrier and integrated valving to provide a controlled ingress of sample gas at nominal pressure differential. The system thereby avoids throttling of the sample gas and the inherent cooling problems associated therewith when the stream is at or below hydrocarbon dew point temperature. The flexible isolation barrier of the present invention is relatively inexpensive and is configured for quick and easy replacement, which may be routinely performed to insure sample integrity. Alternative embodiments of the invention contemplate a spherical sample cylinder configuration with flexible isolation barrier, as well as an improvement for piston-type sample cylinders to provide constant sample pressure.

  • Patent number: 6216549
    Abstract: A collapsible bag sampler comprises a top section; a bottom section connected to the top section; a tail section having fins, which tail section is fitted onto the top section; a nose section with tray, which tray supports a flexible bag; a nozzle holder; a nozzle holder insert in the top section to hold the nozzle; and a flexible bag attached to the outside of the rear of the nozzle holder. Because the bag container is flexible and contains substantially no air, there are no limitations due to air compressibility, meaning the depth to which the sampler could be used would be limited only by the size of the intake nozzle and the volume of the bag. The transit rate is limited only by the apparent approach angle of the nozzle facing into the stream velocity as it makes its vertical descent and ascent (0.4 times the stream velocity). The sampler has a useful range of from 2.0 ft/sec to approximately 10 ft/sec stream velocities.

  • Patent number: 6210640
    Abstract: A collector and method for collecting samples of liquid from at least one source of liquid for automated analysis of the samples. The collector has at least one receptacle for receiving liquid from the source of liquid and holding a quantity of the liquid for obtaining a sample. Each receptacle has an inlet for delivery of liquid from the respective source of liquid and an open top sized to admit the sample collection device into the receptacle. The collector also has a spillway in fluid communication with the open top of the receptacle for receiving excess liquid spilling over the open top of the receptacle. The collector is constructed so that liquid continuously flows through the collector. A drain of the collector receives liquid from the spillway for draining the liquid from the collector.
