Preferred term

Aerolaser AL5002  

Definition

  • The AL5002 from Aero-Laser is a fast carbon monoxide (CO) monitor with a unique sensitivity below 1ppb (parts per billion). The detection of CO is based on a VUV-fluorimetry, employing the excitation of CO at 150nm. This method combines high sensitivity with high selectivity and is linear from 1ppb to 100 ppm. The excitation light is generated by a CW-CO2 resonance lamp, which needs only low maintenance. A monochromator unit, using dielectric mirrors, filters out the VUV from the lamp’s spectrum. The fluorescence light in the wavelength range between 160 nm and 190 nm is detected by a VUV sensitive photomultiplier followed by a fast counter. The AL5002 calibrates within minutes, using only a small amount of calibration gas and an in-built zero gas source. The calibration procedure is fully automatic and can be scheduled in custom-set time intervals. The gas concentration is displayed in real-time and is logged via a standard RS-232 interface. Parameter/diagnostic information (e.g. of pressures, flows, temperatures) are logged simultaneously with the measurement data allowing fast troubleshooting of problems. (en)
