An In Situ, Time-Resolved Analyzer for Aerosol Organic and Elemental Carbon
Open accessAbstract
An in situ carbon analyzer has been developed to investigate the aerosol chemistry of organic carbon. Uncertainties because of sample handling and loss of organic carbon during storage were eliminated by combining the sampling and analysis functions into a single instrument which could operate on a time cycle as short as 90 minutes. Carbon analysis was accomplished with a thermal-optical method with corrections made for the vapor adsorption artifact and for pyrolytic conversion of organic to elemental carbon during the carbon analysis. Total aerosol carbon uncertainties are 3.1% with detection limits of 0.2 μg of carbon. The in situ carbon analyzer was operated during the Carbonaceous Species Methods Comparison Study in Glendora, California, in the summer of 1986. Concentrations of total, organic, and elemental carbon showed strong diurnal variations with peaks occurring during the daylight hours. Comparison of the diurnal profile of organic carbon with those of elemental carbon, a tracer for primary combustion aerosol, and ozone, and indicator of photochemical activity, provided evidence for the secondary formation of organic aerosol in the atmosphere.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
