    • 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 ...
    • 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 ...
    • 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, ...
