In addition to our research, we have executed several research contracts where we have conducted technical assessments, developed test methods/protocols, and performed measurements to examine the influence of fuel additives and fuel treatment and efficacy of emissions control systems. Please contact PI Shantanu Jathar if you would like to use our services for your project needs.
Equipment
At the LAQR, we specialize in the measurement and modeling of air pollutant emissions from energy and combustion sources with a special emphasis on characterizing the size, number, chemical composition, and properties of fine-mode aerosols. We employ the following instrumentation to meet our measurement needs:
Portable dilution tunnel for emissions studies
- Dekati DI-1000 ejector-diluter (baseline dilution of 8:1)
- 200 L residence tank with ports for gas and aerosol sampling
Portable emissions monitoring system
- Global MRV Axion R/S+
- Measures fuel economy, CO2, CO, NOx, HC, and PM at 1 Hz
Portable filter cart for gas/aerosol measurement
- Up to 8 channels to measure gases and aerosols on filters, cartridges, sorbent tubes, and canisters
- Fully-automated with a Raspberry Pi and Python data acquisition system
Environmental chamber for photochemical studies
- 10 cubic meter Teflon FEP bag
- Temperature- and RH-controlled enclosure
- 80 UVA lights (NO2 photolysis rate of 0.25 per min)
- Collapsible mechanism for rapid chamber flushing
Gas analyzers
- LI-COR 840A CO2/H2Oanalyzer
- ThermoScientific 49C ozone analyzer
- ThermoScientific 42C NOx analyzer
- SRI GC-PID hydrocarbon analyzer
Particle analyzers
- GRIMM SMPS+C (long and small DMAs)
- Portable Optical Particle Spectrometer (POPS)
