Determination of dicarboxylic acids in air by aerosol sampler
Čapka, Lukáš ; Mikuška, Pavel
Dicarboxylic acids (DCAs) are important components of water soluble aerosol compounds. Aerosol particles are quantitatively collected using a continous aerosol sampler, CGU-ACTJU, into deionized water. The ACTJU effluent is permanently sucked out from the sampler and on-line analysed for DCAs content by means of ion chromatography.
Determination of inorganic anions in air by modernized aerosol sampler
Čapka, Lukáš ; Mikuška, Pavel ; Večeřa, Zbyněk
Combination of original ACTJU sampler with water-based condensation growth unit (CGU) located upstream of the ACTJU allows quantitative sampling of aerosol particles down to a few nm in diameter. The ACTJU effluent is permanently sucked out from the sampler and online analysed for particulate water-soluble species by ion chromatography.
Increase of efficiency of continuous aerosol sampler
Mikuška, Pavel ; Čapka, Lukáš ; Večeřa, Zbyněk
Contribution deals with increasing of collection efficiency of ACTJU sampler also for particles smaller than 300 nm in diameter. Use of so-called „growth tube“ (GT) located upstream of the ACTJU results in increase of particle size to several µm. Enlarged particles are then easily quantitative collected in ACTJU sampler.
