ON OUR RECENT WORK IN STUDYING NEW PARTICLE FORMATION (NPF)
Kovářík, Jiří ; Špalová, Anna ; Roztočil, Petr ; Zíková, Naděžda ; Schwarz, Jaroslav ; Ždímal, Vladimír
New particle formation (NPF) is increasingly gaining attention since it emerged roughly twenty years ago as a field of interest within the aerosol science. It studies the transition process between gas phase molecules, forming clusters and eventually becoming aerosol particles. Thus, this field is a multidisciplinary one, ranging from meteorology, atmospheric chemistry and physics, all the way through physical chemistry towards chemistry and physics of aerosols. \nRecent development of instrumentation techniques allows measuring of sub-5 nm particles and molecule clusters, neutral and also charged ones. Therefore, modern analytical methods based on these measurements are often used for NPF studies.

INTRODUCTION TO PRAGUE AEROSOL CALIBRATION CENTER
Ondráček, Jakub ; Roztočil, Petr
In general, the PACC offers a range of services, from calibration and consulting to methodology and technical development. Furthermore, the PACC has the capacity to organize and perform training for microphysical (including optical in the near future) aerosol in-situ instrumentation. The equipment at the PACC is fully in-line with the state of-the-art aerosol instrumentation (starting from various aerosol generators for welldefined nanoparticles, reference instruments, and newly designed calibration lines) and the laboratory space is flexible for various types of instrument calibration/verification/intercomparison or testing of newly developed, cutting-edge equipment.

Verification of Electrical and Gravimetric Measurement of ELPI.
Ondráček, Jakub ; Roztočil, Petr ; Ondráčková, Lucie ; Vlčková, Lucia ; Benešová Ševčíková, Irena ; Procházková, Věra ; Kugler, Josef ; Otáhal, P.
This contribution compares the gravimetric and electrical measurement of ELPI impactor with traditional and very well-established aerosol spectrometers (SMPS, APS and CPC)\non set of well-defined aerosols (different composition, sizes and morphology).
