2.2. Qualitative identification of emitted VOCs
Ten most abundant VOCs were analyzed by GC/MS and searched in
NIST 2011 library and by use of AMDIS (Ver. 2.7); for analytic details,
see below. Identification, in general, was based on inspection and
considered positive by library search match N800 for both forward
and reverse matching. A further criterion was retention time (tR)
identification with an authentic standard within tR ± 0.03 min, when
applicable.
