From Sep 30 to Oct 21, 2011 one fast response O3 detector
was equipped with the commercially available discs (BAGUS
Consulting GmbH) and the other O3 detector was equipped
with discs prepared using the EAM8. Both disc types were
exposed to elevated O3 mixing ratios using an ozonizer (GFAS
Ozonizer PR-S-2, GFAS GmbH, Germany) prior to each
individual application in the field for 1 h (BAGUS) and for 5 h
(EAM8), respectively (for further explanation see below).
