Abstract: A non-dispersive infrared (NDIR) multi-gas analyzer (405) has an optical element (950) that is positioned with respect to the axis of incident IR radiation such that it passes nearly all of the IR energy within a narrow band pass to one detector (540) and reflects nearly all of the IR energy outside the narrow band pass to another detector (535). Thus, the optical element (950) simultaneously functions both as a narrow band pass filter and a beam splitter, which transmits nearly all the IR radiation within a band pass and reflects nearly all the IR radiation outside the band pass. Additionally, the separation of the incoming energy can be achieved without an extended roll off. This allows using a reference transmission band that is very close to the absorption band of the gases of interest. It more specifically allows using a reference transmission band that is located between the absorption bands for hydrocarbons and carbon dioxide in an infrared analyzer that uses beam splitters.

Abstract: A filter assembly (100) for preparing gases for an exhaust gas analyzer has a single housing (101) including at least three filter cavities (103), (105) and (107), an inlet passage (180) and two outlet passages, (284) and (182). First filter cavity (103) includes a coarse filter, (121) through (125), for filtering particulate matter and for condensate condensation, with condensate draining into second filter cavity (105), which has disposed therein a fine filter (141), (142), for filtering condensate. Outlet passage (284) connected to second filter cavity (105) allows withdrawal of the condensate. Third filter cavity (107) has a fine filter (160) for filtering the exhaust gas and is coupled to first filter cavity (103). Second outlet passage (182) connects the third filter cavity (107) to a pump for removal of the gas to be analyzed. A multiple filter assembly in a single housing with large fine filter area, minimal void volume, minimal interconnections, and convenient access to the individual filters is provided, which achieves precise filtration of gases for analysis.

Abstract: An improved sensor support subassembly (10) for a chemical sensor (12) in the testing of gaseous emissions. The sensor subassembly (10) includes a sensor unit (12) slidably engaged with a gas intake manifold block (40). The sensor unit (12) has a cylindrical base (20) which forms the sensor inlet (26). The manifold block (40) includes a gas intake (46), a gas channel (42), and a U-shaped slot (50, 50a) for slidably engaging the cylindrical base (20) within the manifold block (40) to form an air-tight passage between the sensor inlet (26) and the gas channel (42). The sensor subassembly (10) also includes a sealing ring (34) for insuring an air-tight seal between the sensor unit (12) and manifold block (40). This allows the sensor unit (12) to be rotated about the axis of the cylindrical base (20) and use of a card-edge connector (16).

Abstract: An apparatus and method for measuring the concentration of carbon dioxide in respiratory gases. The apparatus is a non-dispersive gas analyzer (100) attached in series with the respiratory airway which is universally compatible with any host system. The analyzer (100) includes a housing (102) which supports a sample cell containing the respiratory gases, and which contains an infrared radiation source (130) encased in shock absorbing material, means for directing the radiation into a collimated beam through the sample cell, means (145) for splitting the beam and directing it towards two infrared detectors (142, 146) for measuring the amount of absorption of carbon dioxide in the sample cell. The analyzer has two heating servos (118, 152), one regulating the temperature of the sample cell windows to inhibit condensation build-up and one regulating the ambient temperature surrounding the detectors (142, 146) to ensure more accurate measurements. Calibration means within the analyzer housing (102) stores and provides information characterizing performance parameters of the analyzer (100).

Abstract: An improved gas analyzer for measuring the presence of one or more gaseous compounds in a gas sample. The gas analyzer has an infrared source stabilized against temperature variations by a radiation loading scheme in combination with a selected source environmental temperature sensitivity to provide a stable source temperature without a conventional temperature controller. A rotating interference filter assembly is disposed in the optical path. This assembly alternately totally blocks radiation, passes radiation in a wave length band which will not be absorbed by a random gas sample, and sequentially passes radiation in one or more additional bands which will be absorbed by one or more gases in the sample cell. The sample cell features a unique enclosed cell with infrared transparent windows which are substantially free of impingement of contaminants of the gas sample thereon. A unique detector provides protection against deterioration from moisture while allowing easy and inexpensive assembly. The system electronics eliminates sensitivities to background radiation, contamination of windows, etc., and provides a self test capability.

Abstract: A cassette is described for use in an intravenous delivery system having a pump. The volume of a main chamber defined by the cassette body is varied by a membrane in a wall thereof while unidirectional inlet and outlet valves maintain the direction of fluid flow into and out of the main chamber. A prechamber is positioned above the inlet port in order to accumulate air from the upstream portion of the intravenous delivery system in which the cassette is used.

Abstract: A spectrophotometer sample cell is described having a housing defining a frusto-conical chamber with inlet and outlet windows at each end. The inlet window is positioned toward the energy source of the spectrophotometer and the outlet window, which is the larger diameter window, is positioned toward the detector assembly of the spectrophotometer. A single outlet passage is positioned between a pair of inlet passages, the latter being toward respective ends of the chamber. The interior surface of the sample cell is provided with means for preventing a substantial portion of reflected energy impinging on the sample cell walls from reaching the detector. Such means include irregularities, annular walls, and wavelength absorbing colors. A trough is provided in the bottom of the larger end of the frusto-conical chamber for conveying condensate to the outlet passage.
