Abstract: An exhaust gas sampling apparatus for analyzing the contents in exhaust gas. The sampling apparatus intakes air from an air intake conduit and mixes the air with exhaust gas taken from an exhaust gas supply conduit. The mixed gas can be sampled in different sampling conduits based upon the type of exhaust gas being examined. The apparatus includes heaters for heating various conduits to prevent condensation from forming within the conduits.

Abstract: A system for a sampling hydrocarbon containing gas flowing in a pipeline by collecting a fluid sample in a sampler bottle 55 includes a sample probe 12 secured to and extending outward from the pipeline, a heater body 20 removably secured to the probe, and vortex heater 34 for outputting a cold fluid and hot fluid. The heater body 20 has flow path therein for directing the hot fluid to heat the sample probe, and preferably thereafter heat the bottle 55. The pressurized gas to the vortex heater may be supplied directly from the pipeline P, with pressure control by a regulator 24. Alternatively, pressurized gas such as air may be stored in a portable vessel 172 for supplying compressed air to the vortex heater 34. An improved method of sampling gas in a pipeline using the vortex heater is disclosed.

Abstract: The sampler comprises a vessel assembly for taking, conducting, and storing a fluid sample to be stored at a predeterminable storage temperature as well as a cooling assembly, thermally coupled to the vessel assembly, for cooling the fluid sample. The cooling assembly has a first cooling volume, which encompasses the vessel assembly, and a second cooling volume, which jackets the vessel assembly. To cool the fluid sample, the internal temperature of the vessel assembly is lowered by means of the cooling assembly prior to and/or during the dispensing of the fluid sample, and the fluid is subsequently conducted or held in the vessel assembly.

Abstract: A temperature-adjusted sampler for liquids, gases or other fluids including a hollow needle in steel or another metal on which a heating is deposited so as to be electrically insulated, characterized in that the hollow needle is coated with an electrically insulating layer which has deposited thereon in complete intimate contact a thin, electrically conducting heating layer.

Abstract: An apparatus and method for sampling gases at elevated temperatures which is amenable to analysis in a manufacturing environment is described. In particular the method and apparatus can be used to determine accurate compositions of gas mixtures contained in blisters of elastomeric products. The device comprises a syringe 15,15a and a heated block 12,12a for receiving and holding syringe 15,15a, and for preheating or maintaining the temperature of syringe 15,15a. A thermostat may be associated with heating block 12,12a for controlling its temperature close to the temperature of a product from which a gas sample is taken.

Abstract: A system for analysis of vapor constituents in a gaseous and/or liquid media includes an analyzing gas chromatographic unit, an in-line preconcentrator assembly having a trap housing, an adsorbent material received in the trap housing, and a transfer line unit couplable to the trap housing and directly connected to the analyzing unit. Carrier mechanism drives the trap housing with respect to the transfer line unit linearly or along an arc trajectory. When the trap housing is displaced from the transfer line unit, the media surrounding the trap housing is forced inside of the trap housing by a pump and vapor constituents are adsorbed on the adsorbent material within the trap housing. When the trap housing is moved in pressure tight engagement with the transfer line unit, the adsorbent material is heated to release the vapor constituents from the adsorbent material.

Abstract: A sample transport device for use in analyzing samples by the headspace analysis technique. The device has a cylindrical platen with counterbored chambers for accepting sample vials. The platen is heated and caused to rotate from a first vial transport point to a sampling point and then back for ejection of the sample vial. Vertical movement of the sample vials is accomplished by use of elevator rods connected to level winding screws mounted below the cylindrical platen.
