    摘要： An optical gas analyzer for measuring the percentage of components in a gas phase by IR absorption, containing a power source, a measuring path containing the gas sample, a photoelectric receiver with an evaluation circuit arranged downstream of it, which receiver detects the IR radiation from the measuring path, and a plurality of filters, which can be introduced one after another into the beam path at a predetermined filter change frequency f, wherein measured signals belonging to the filters are sent by the receiver due to the radiation extinction in the measuring path, is to be improved such that different components in the gas sample can be detected in a simple manner and at good selectivity. To accomplish this object, the receiver is a pyroelectric detector, the evaluation circuit has elements for the evaluation of the voltage signal of the pyroelectric detector, the filter change frequency f is set at a value in the range of the declining branch of the frequency response of the voltage signal, and the pyroelectric detector is selected to be such that the declining branch of the voltage signal has a decline of -20 dB per decade.

    摘要： A breathing gas system and water trap (1) is improved in respect to the reliability of operation and has an emptying device. The water trap (1) has a gas inlet (4), which meets a first water separating membrane (5) via a connection line. The connection line leads into a water tank (20) located deeper in the incoming flow direction from the first water separating membrane (5) and into a gas measuring device (2) with vacuum on the discharge side from the first water separating membrane (5) from the water trap (1). The water tank (20) has a rinsing gas flow line, which is arranged above the liquid level, leads upward via a gas-permeable membrane (6) and is likewise connected to the applied vacuum of the gas measuring device (2). The water tank (20) has a water transport line for emptying the water tank (20), which water transport line extends into the liquid and is provided with a downstream vacuum via a nonreturn valve (7) and a downstream liquid pump (17) or via a solenoid valve (21). The water trap (1) is equipped with a filling level detection system (8, 9, 22; 8, 9, 13; 8, 10), which is connected to a control and analyzing unit (3). The control and analyzing unit (3) is connected to the liquid pump (17) or to the solenoid valve (21), so that the water tank (20) can be emptied as a function of the signal of the filling level detection system (8, 9, 22; 8, 9, 13; 8, 10).

    摘要： A device for the analysis of the qualitative, optionally also the quantitative composition of gases, uses measuring light of known spectral composition that can pass through the gas to be analyzed and the gas can be caused to interact. A detector arrangement is present, which can detect light originating from the sites of the interaction between the measuring light and the gas to be analyzed. At least one refractive-diffractive optical element is provided, which is transparent over its entire surface and contributes to a wavelength-dependent imaging of the light to be detected onto the detector arrangement in a transmitting manner. The refractive-diffractive optical element is arranged in the ray path between the area in which the interaction between the gas to be analyzed and the measuring light takes place and the detector arrangement.

    摘要： A water trap for a sample gas flow includes a housing 1 fastened to a holder 2. The housing 1 has a tank 3 for receiving liquids and gases. Above the tank 3, the housing 1 contains a first chamber divided by a first hydrophobic membrane 10. The lower divided part 12 of the first chamber is connected to the sample gas flow via the holder 2 on the inlet side and to the gas space in the tank 3 on the outlet side. The upper divided part 11 of the first chamber is connected to a gas analyzer 4 via the holder 2 and is connected to a vacuum. The housing 1 contains a second chamber divided by a second hydrophobic membrane 20. The lower divided part 22 of the second chamber is connected to the gas space in the tank 3 at a point 18 which is located lower in the direction of the liquid level and relative to the entry of the connection line from the first chamber. The upper divided part 21 of the second chamber is connected to a volume flow meter 8 and to the same vacuum. The free areas through which the gas flows and the pore sizes of the first and second hydrophobic membranes are selected so that the ratio of the gas volume flow through the first and second hydrophobic membranes is in the range of 5:1 to 20:1.
