techniques, three of them employing PTV, were tested in our<br />
study.<br />

Generaly, the nCI mode provided signifficantyl lower<br />
LODs compared with EI mode coupled to all tested GC/<br />
MS system.<br />
The lowest LODs were obtained by GC/MS coupled to<br />
the PTV injection operated in nCI mode, under these<br />
conditions large quantity of analytes without solvent<br />
(due to PTV injection) and high selectivity for bromine<br />
ions (due to MS-nCI mode) could be performed.<br />
PTV-GC/TOFMS employing splitless injection provided<br />
similar results in comparison with GC/MS (nCI)<br />
using splitless injection.<br />
This study was undertaken within the projects MSM<br />
6046137305 and NPV II (2B06151) both supported by the<br />
Ministry of Education, Youth and Sports of the Czech Republic.<br />
