On-line Measurements of Very Low Concentrations of EC/OC Aerosols at a Finish Sub-Arctic Backround Station.
Vodička, Petr ; Schwarz, Jaroslav ; Brus, David ; Ždímal, Vladimír
In this work, we tested the possibilities of an on-line Sunset Lab. EC/OC analyser during measurements when aerosol concentrations were close to detection limits declared by the manufacturer.

Possible Relations between Organic Aerosol Analysed by Aerosol Mass Spetrometer and EC/OC Analyzer
Vodička, Petr ; Makeš, Otakar ; Kubelová, Lucie ; Schwarz, Jaroslav ; Ždímal, Vladimír
Analysis of carbonaceous aerosols by elemental and organic carbon (EC/OC) analyzer can provide additional information in the form of OC fractions. These may improve characterization of organic aerosol. We compared two sets of PM1 aerosol data – summer (22.-26.6. and 13.-31.7.2012) and winter (12.-29.1.2013) – measured at a Prague urban background site (50°7′36.47″N, 14°23′5.51″E, 277 m ASL). We wanted to determine whether the OC fractions from EC/OC analyzer can indirectly provide also information on the chemical composition or in other respects improve aerosol characterisation.

Comparability of Methods to Measure Black and Elemental Carbon in Two European Urban Areas - Site and Seasonal Similarities and Differences

The goal of the current study is to investigate whether similar conversion factors are applicable at the sites and whether the conversion factors obtained earlier (i.e. ca. 10 years ago) for Vienna are still valid or whether changing source conditions have resulted in shifts of the carbonaceous fractions of the aerosol that would require a new set of conversion factors.

Application of difusion denuder for sampling of carbonaceous aerosols and analysis of OC/EC
Mikuška, Pavel ; Večeřa, Zbyněk ; Bartošíková, Anna ; Maenhaut, W. ; Chi, X.
Annular diffusion denuder for sampling of carbonaceous aerosols on quartz filter without interferences of gaseous organic pollutants and atmospheric oxidants is described. Exposed filters are analysed off-line for content of orgnic and elementar carbon in collected aerosols.
