Now LGR offers an expanded line of high speed (10 Hz) and lower speed (up to 1 Hz) gas analyzers that can be used for all four techniques to measure a wide variety of gases.
Two important accessories are also available:
Multi-Channel Data Logging Software: Synchronizes serial (RS-232) outputs from multiple LGR analyzers and other devices, such as GPS or sonic anemometers, and records all data with a common time stamp.
Multiport Inlet Unit (MIU): Available with either 8 or 16 inlets and 1 output port which is used to connect to the Analyzer. The MIU inputs are fully controlled by software on the LGR Gas Analyzer so that any port may be selected at any time. Once programmed, the sequence of measurements is fully automated.
Here is a list of the LGR analyzers that can be used for each flux measurement technique:
Eddy Covariance Technique »
For New Eddy Covariance Sites: Choose the high speed, high precision LGR analyzer(s) listed below based on which gases you want to measure. You can connect the analyzer(s) to a datalogger or use the LGR multi-channel data logging system to connect a sonic anemometer available from various manufacturers such as Campbell Scientific, Gill, Applied Technologies (ATI), Metek, RM Young, or Kaijo-Denki.
For Existing Eddy Covariance Sites: Expand your system by adding any of these high speed, high precision LGR analyzers. You can connect the analyzer(s) to your existing datalogger.
- Greenhouse Gas Analyzer to 10 Hz: The world's most advanced analyzer for simultaneous measurements of CH4, CO2 and H2O.
- Fast Methane Analyzer to 20 Hz: For simultaneous measurements of CH4 and H2O with unsurpassed precision, accuracy and dynamic range.
- OCS Analyzer to 10 Hz: For simultaneous measurements of COS (Carbonyl Sulfide), CO2, CO and H2O with extraordinary precision and sensitivity.
- Carbon Dioxide Analyzer to 10 Hz: For simultaneous measurements of CO2 and H2O with unsurpassed precision, accuracy and dynamic range.
- CO/CO2 Analyzer to 10 Hz: For extremely high precision and simultaneous measurements of CO, CO2 and H2O.
- Carbon Monoxide Analyzer to 10 Hz: For simultaneous measurements of CO and H2O with unsurpassed precision, accuracy and dynamic range.
- N2O/CO Analyzer to 10 Hz: For simultaneous measurements of N2O, CO and H2O with unsurpassed precision, accuracy and dynamic range.
- Trace Ammonia Analyzer to 10 Hz: Measurements of NH3 with unsurpassed precision, accuracy and dynamic range.
In addition to the high speed, high precision analyzers, LGR offers the most complete line of isotope analyzers:
- Carbon Dioxide Isotope Analyzer (CO2, δ13C, δ17O, δ18O): Model CCIA-46 (Enhanced Performance) provides measurements of δ13C, δ17O and δ18O, as well as mole fraction of carbon dioxide, with extraordinary precision at measurement rates of up to 5 Hz.
- Carbon Dioxide Isotope Analyzer (CO2, δ13C, δ18O): Model CCIA-36 (Enhanced Performance) provides measurements of δ13C and δ18O as well as mole fractions of carbon dioxide and water vapor with high precision at measurement rates of up to 1 Hz.
- Carbon Dioxide Isotope Analyzer - Elevated CO2: It provides many features that researchers need when measuring isotopic carbon dioxide from samples containing high levels of CO2 including ultra-low drift and high precision, ability to measure CO2 as well as δ13C and δ18O in CO2 from 2% to 100% CO2 and fast response.
- Methane Carbon Isotope Analyzer (CH4, δ13C): It provides sub ppm precision of δ13C in CH4 with a rapid response time. Because it does not require user intervention, this instrument also enables long-term methane isotope monitoring studies.
- Isotopic N2O Analyzer (N2O, δ15N, δ18O): The world's first commercially available laser-based gas analyzer that measures isotopic site-specific (15N) nitrogen in N2O.
- Water-Vapor Isotope Analyzer (H2O, δ2H, δ17O, δ18O): Now you can accurately measure δ17O, δ18O and δ2H in ambient water vapor (to over 60,000 ppm) rapidly with high precision in a measurement time of less than 0.5 seconds.
