Abstract: An integrated sampling device with liquid eliminator is provided. The device includes a body with integrated valving. A liquid eliminator device is provided within the body and interposed in a flow path such that gas will pass through and liquid will not. The gas will then be conducted to a sampling device while the liquid will pass through an exhaust port back to the source of fluid. An inlet valve is also provided to control the flow of fluid from the source to the liquid eliminator element. An outlet valve may be provided to control liquid back to the source.

Abstract: Sidestream gas sampling assembly that does not substantially degrade the waveform of expired gases. The gas sampling assembly includes a sample cell portion integrated with a filter portion for separating undesired liquid condensate from respiratory gases to be monitored. The gas sampling assembly is configured to receive expired gases through a gas sampling line, filter undesired liquid condensate from the expired gases through hydrophobic fiber elements and communicate the filtered gases to a sample chamber which is in close proximity to the filter where measurements may be taken thereof e.g., optical or infrared sensing mechanisms. The gases that are substantially free of liquid condensate are then exhausted from the sample chamber.

Abstract: An exhaust gas measurement system is provided that includes a probe to find a sample exhaust gas passageway for collecting exhaust gas. A stainless steel canister is fluidly connected to the probe for storing the exhaust gas. A pump fluidly interconnects the probe and the canister for transferring the exhaust gas from the probe to the canister. A pressure mass flow controller fluidly interconnects the probe and the canister and produces an exhaust gas flow measurement corresponding to the flow of the exhaust gas from the probe to the canister. A temperature sensor senses a temperature of the exhaust gas proximate to the pressure mass flow controller. The temperature sensor corrects the exhaust gas flow measurement based upon the temperature sensed. A pressure sensor senses a pressure of the exhaust gas proximate to the pressure mass flow controller. The temperature sensor corrects the exhaust gas flow measurement based upon the pressure sensed. The mass flow controller can be controlled by an external source to account for flow changes in the CVS system. A heating device heats the stainless steel canister and other components of the exhaust gas measurement system such as the pressure mass flow controller to a temperature of preferably approximately 191null C. Another heated pressure mass flow controller may also be used to determine the amount of exhaust gas that is transferred from the canister to an analyzer for the actual determination of the hydrocarbons.

Abstract: A microsensor housing having a structure with at least one inlet at one end and a thermal property sensor at the other end. Situated between the inlet and the sensor is a convection shield. Sampled fluid is taken in the inlet from a channel carrying the fluid to be sampled. The convection flow lines of the fluid are barred by the convection shield. The fluid is diffused into a cavity between the shield and sensor. The sensor detects a thermal property of the diffused fluid. One preferred shield has holes about its perimeter with a solid center part of the shield covering at a distance the sensor. The channel carrying the fluid may have screens to reduce turbulence noise and to aid in fluid transport to and from the sensor housing.

Abstract: A portable apparatus for continuous real-time measurement of airborne met, comprising an isokinetic sampler, a sample line, a sampling interface device, a pump, and an inductively coupled plasma atomic emission spectrometry (ICP-AES). A method for measurement of airborne metals by use of such an apparatus is also described, in which the sampling interface device accommodates the high, continuous sample collection flow-rates necessary for isokinetic sampling while at the same time permits sample air to be introduced into the plasma at preferred moderate flow-rates. A method for field standardization of the ICP-AES is also described whereby a relationship between aqueous solutions of metals and their aerosol counterparts is established, thus later allowing the field use of the aqueous metal solutions to simulate a particular range of airborne metal concentrations.

Abstract: A method an apparatus for measuring a base condition volumetric flowrate of a pipeline gas flowing through a pipeline in which a pipeline gas flowrate is measured by a pipeline gas flowmeter; a volumetric correction ratio is derived by: measuring a sample gas flowrate of sample gas tapped from the pipeline, measuring an energy flowrate of the sample gas, measuring a heating value of the sample gas, and measuing a base condition density of the sample gas; and the base condition volumetric flowrate of the pipeline gas flowing through the pipeline is determined by adjusting the pipeline gas flowrate as measured by the pipeline gas flowmeter by the volumetric correction ratio. The temperature of the sample gas should be substantially the same as the pipeline gas in the pipeline when the sample gas flowrate is measured.

Abstract: Disclosed herein is a gas atmosphere sampling system for analyzing the oxygen partial pressure in a gas carburizing atmosphere. The system is appropriate for remote sensing of gas atmosphere when the probe can't be fitted in the heat treating apparatus. Sooting of the sampled gas tube and probe is eliminated by use of ceramic, non-catalytic surfaces in the measuring vessel. A ceramic feed pipe, with a small diameter, introduces the gas atmosphere to be measured into the vessel and increases the velocity of the gas atmosphere to avoid sooting.
