Synspec - Model LSE N2O-4405 -Ultra Sensitive N2O Monitor for Ambient Air and Stack Measurements
Nitrous oxide (N2O) is a man-made green house and ozone depletion gas. Emissions from agriculture are the main source, followed by industry and energy plants. Although the concentration of N2O in the atmosphere is relatively high (330 ppbv), the day and night fluctuations are small and so are seasonal differences. Therefore, highly sensitive and stable instrumentation is needed to monitor N2O emissions in the atmosphere. This instrumentation was not commercially available up till now.
For the detection of N2O, LSE Monitors developed a highly sensitive laser-based photoacoustic detector, able to monitor continuously and on line the concentration of N2O with a detection limit below one ppbv within several minutes. The detector is specifically designed to work stand alone with virtually no maintenance. It is robust and has a user-friendly software. The monitor is designed to keep the cost of ownership as low as possible.
