Gas lamps - Import export

The wavelength meters of the WS series accomplish wavelength measurements with highest accuracy. Both cw and pulsed lasers with narrow-band emission can be examined, monitored and even actively controlled. Various models of the WS series are available, covering UV to IR wavelength ranges (192 nm - 11 µm). Based on a rugged Fizeau interferometer setup without any moving components, the wavelength meters provide quasi unlimited lifetime.The spectrum analyzers LSA and HDSA allow for multi-line or broadband spectrum of light sources like cw and pulsed lasers, gas discharge lamps, super luminescence diodes, semiconductor laser diodes and LEDs.

For the detection of NO and H2S an EDL (electrodeless gas discharge lamp) is used. A combination of both technologies (UVRAS & UVLEDs) allows simultaneous gas analysis of NO, NO2 and SO2 in the lower ppm range, which is particularly important in flue gas analysis (CEM)2. In the EDL, N2 and O2 are converted to NO and produce selective UV radiation. With this radiation a cross sensitivity free NO measurement is made possible. This method is called UV resonance spectroscopy (UVRAS). Applications Exhaust gas monitoring (CEM)2 Laboratory area Biogas research Industrial gas analysis Engine test benches Portable gas analysis (PEMS)3 Features & Benefits Simultaneous NOx and SO2 analysis Temperature controlled up to 55°C Fast response time < 3 seconds Durable EDL (> 16000h) Flow-independent measurement 0-2L/min No influence of gas humidity No NOx converter required High accuracy Low power consumption Compact size
