testing of volatile organic compounds (VOCs) from building materials requires
a climatic chamber in which certain parameters are controlled during the
test period, in addition to a clean air supply. The important parameters
which can be controlled in climatic chambers are the air exchange rate
and the air velocity, the temperature, and the relative humidity. These
and the recovery of important VOCs, the chamber tightness, and the sink
properties could form the required performance criteria of a climatic chamber
including the overall analytical performance. The recovery of VOCs and
the time to reach quasi chamber equilibrium concentration, to some extent,
reflect the sink property of the chamber wall (chamber inertness) and the
chamber tightness. |
