The EC9820 Carbon Dioxide Analyser , developed and manufactured by Ecotech in Australia, combines microprocessor control with NDIR gas filter correlation photometry detection to measure CO2 with minimal interference from CO and H2O The CO2 concentration is automatically corrected for gas temperaturepressure changes and can be displayed in units of ppm or mgm3. The EC9820 allows for a manual, timed or remote initiated zerospan calibrations. Special features: The EC9820 uses a long life infrared (IR) source and advanced materials in the gas filter wheel to deliver trouble free operation and minimum maintenance Variable sample flow rate allows for faster purging during zero and span cycles. The variable flow rate enables the analyser to obtain more data points at ‘steady state’ zero and span conditions Optional permeation dryer for removal of H2O from sample air Internal data logger and communication via RS 232, USB, TCPIP Ethernet option facilitates data download from an analyser connected to the internet via a standard web interface. This feature also supports remote access to instrument parameters and the status screen

The DRI Model 2015 Multiwavelength ThermalOptical Carbon Analyzer enhances the widely-used DRI Model 2001 system for quantifying organic carbon (OC), elemental carbon (EC, also termed Black Carbon [BC]), and temperature-separated carbon fractions on aerosol filter deposits. The Model 2015 retains OC and EC consistency with previous measurements while reducing costs of supplies and maintenance compared with the Model 2001. It replaces the 633 nm optical monitoring that accounts for OC charring with reflected (R) and transmitted (T) intensities at wavelengths of 405, 445, 532, 635, 780, 808, and 980 nm. The additional optical information can be used to estimate multiwavelength light absorption of the sampled particles, quantify the concentration of brown carbon (BrC) in each sample, and further complement the use of carbon fractions in source apportionment studies. Model 2015 software includes temperature programs for commonly-used protocols such as IMPROVE_A, EUSAAR, and NIOSH, and it can be programmed to emulate any other protocol. The simultaneous measurement of both R and T at all wavelengths throughout each analysis allows for reproducing any other thermaloptical method and holds potential for better characterizing additional properties of the carbonaceous aerosol.
