Such selectivity is requested in plants using or producing extremely toxic substances. These plants always have a „Zero Emission Policy“ in force. Here high sensitivity in combination with good selectivity is required. Sensor technology Electrochemical sensors can be designed to be very selective and sensitive at the same time by the right material choice for electrodes and electrolyte. These sensors will not respond to less dangerous substances that might be around in the plant such as hydrocarbons, carbon monoxide, hydrogen or even humidity. A detection limit of Phosgene as low as 2 ppb is no problem for this sensor technology! A disadvantage of electrochemical sensors compared to physical methods has been their comparatively slow response. The working electrode must transform analyte to confer a response – and this takes its time. Tests in Compur`s laboratories have shown that the material transformation process at the working electrode can be speeded up by increased mass transfer of analyte to sensing surface compared to gas access by diffusion. It was a short step from there to develop an instrument with a built-in pump and a special measuring chamber with optimized flow characteristics. In this way the response time of the instrument is almost as short as would be obtained with a physical detection method. The Tracer is capable to detect even traces of toxic gases. The detection limit is in the low ppb range depending on the substance to be detected. As a leak detector might be exposed to very high concentrations, it must not be used as a personal monitor. To avoid it being abused as such, it displays no concentration, but only a dimensionless figure or a bar graph. Using the Tracer To locate a leak, move the sample intake along the surface to be inspected. The measured value will increase when a leak is approached. The display can be selected between bar graph and digital. A control tone and LED will increase in frequency with mounting measured value similar to a Geiger counter. The Tracer will protect itself from poisoning. If the measured value goes out of range the pump will go off and start again when it drops below 95% of the range. The graphic display is easy to read. At night or in dark places in the plant a backlight can be switched on. Consumables such as sensor, filter or sampling probe can easily be replaced without tools. Field test results – the high range version The first tests in plants have proven that an ultra-low measuring range does not always do the job. Therefore the Tracer product range is completed by a new HIGH range version. It uses an orifice in front of the sensor increasing the measuring range by a factor of 20. The user can do that without changing the amplifier adjustment. All it takes is just replacing the LOW range sensor by a HIGH range sensor and so cover a measuring range from the low ppb range up to the two digit ppm level! 便攜式有毒氣體泄漏檢測儀/手持式氣體檢漏儀 | COMPUR MONITORS 便攜式有毒氣體泄漏檢測儀/手持式氣體檢漏儀 ppb級檢測 德國COMPUR TRACER |
