ABSTRACT
A laboratory study was performed to demonstrate applicability of
VOST (SW846 Methods 0030 and 5041) and SemiVOST (SW846 Method
0010, Draft Method 3542, and Method 8270) for collection and
analysis of nonhalogenated organic compounds listed in Title III of
the Clean Air Act Amendments of 1990.  Compounds with (boiling
points ?132? were selected as candidate VOST analytes, and VOST
analyses (Method 5041) of spiked sorbent tubes were performed to
demonstrate successful analysis.  Analytes with recovery ? 50% were
prepared as a single certified gaseous standard.  VOST dynamic
spiking studies were performed in the laboratory.  For semivolatile
and nonvolatile compounds (boiling points ?100?C), GC/MS analyses
(Method 8270) were performed on analytes combined in a single
solution.  Several instances of chemical incompatibility and poor
solubility were encountered, and these analytes were eliminated
from further study.  Laboratory SemiVOST dynamic spiking studies
featured acid/neutral analytes and base/neutral analytes in
separate solutions; two sets of experiments were performed.  All
compounds with recoveries ?50% will be tested in a field dynamic
spiking study.
