    • A high-flow humidograph for testing the water uptake by ambient aerosol 

      Khlystov, Andrey; Kos, GPA; Kreyling, Wolfgang; Roth, Christa; ten Brink, Harry M; Tuch, T (ATMOSPHERIC ENVIRONMENT, 2000)
      A ``humidograph{''} with an air flow rate of 0.4 m(3) s(-1) was built to investigate the uptake of water and its effect on sizing, collection and light scattering of ambient aerosol. In the humidograph the relative humidity ...
    • A high-flow turbulent cloud chamber 

      Khlystov, Andrey; Kos, GPA; ten Brink, Harry M (AEROSOL SCIENCE AND TECHNOLOGY, 1996)
      A large laboratory facility (cloud chamber) has been built to study cloud formation under reproducible conditions. The chamber was designed to assess the influence of anthropogenic aerosols on the microstructure of marine ...
    • Activation properties of ambient aerosol in the Netherlands 

      Berner, A; Khlystov, Andrey; Kos, GPA; Kruisz, C; ten Brink, Harry M (ATMOSPHERIC ENVIRONMENT, 1996)
      A cloud chamber has been used to study the cloud activation of ambient aerosol in The Netherlands. The large dimensions and throughput of the chamber allowed unperturbed collection of aerosol and droplets with cascade impactors ...
    • An approach to monitor the fraction of elemental carbon in the ultrafine aerosol 

      Hoek, G; Khlystov, Andrey; ten Brink, Harry M (Atmospheric Environment, 2005-10-01)
      Attempts were made to measure the fraction of elemental carbon (EC) in ultrafine aerosol by modifying an Ambient Carbonaceous Particulate Monitor (ACPM, R&P 5400). The main modification consisted in placing a quartz filter ...
    • Comparability of three spectrometers for monitoring urban aerosol 

      Khlystov, Andrey; Kos, GPA; Kreyling, Wolfgang; Mirme, A; Roth, Christa; ten Brink, Harry M; Tuch, T (ATMOSPHERIC ENVIRONMENT, 2001)
      The comparability was tested of three aerosol ``spectrometers{''}, used in a program for monitoring the spectra of fine and ultrafine particles in three European cities. Droplets of sebacate, solid ammonium sulfate ...
    • Concentrations of ultrafine, fine and PM2.5 particles in three European cities 

      Brunekreef, B; Buzorius, G; Khlystov, Andrey; Kos, GPA; Kreyling, Wolfgang; Mirme, A; Pekkanen, J; ... (13 authors) (ATMOSPHERIC ENVIRONMENT, 2001)
      Total number concentrations, number concentrations of ultrafine (0.01-0.1 mum) and accumulation (0.1-0.5 mum) particles, as well as mass concentration of PM2.5 particles and blackness of PM2.5 filters, which is related to ...
    • Fate of products of degradation processes: consequences for climatic change. 

      Khlystov, Andrey; Slanina, J; ten Brink, Harry M (Chemosphere, 1999-03)
      The end products of atmospheric degradation are not only CO2 and H2O but also sulfate and nitrate depending on the chemical composition of the substances which are subject to degradation processes. Atmospheric degradation ...
    • Intercomparison of aerosol spectrometers for ambient air monitoring 

      Khlystov, Andrey; Kreyling, Wolfgang; Mirme, A; Pekkanen, J; Ruuskanen, J; ten Brink, Harry M; Tuch, T (AEROSOL SCIENCE AND TECHNOLOGY, 2002)
      Three aerosol spectrometers measuring the number concentration distribution of particles in the diameter range 0.01 to 2.5 mum were compared by running them side-by-side for 385 h under ambient air conditions in Erfurt, ...
    • The continuous analysis of nitrate and ammonium in aerosols by the steam jet aerosol collector (SJAC): extension and validation of the methodology 

      Even, A; Hu, M; Jongejan, P; Khlystov, Andrey; Otjes, RP; Slanina, J; ten Brink, Harry M; ... (8 authors) (ATMOSPHERIC ENVIRONMENT, 2001)
      Classical methodology based on the application of filters for sampling, followed by extraction and analysis, introduces severe artifacts for semi-volatile compounds like ammonium nitrate. These filter methods do not meet ...
