D. Fraisse et al., IMPROVEMENTS IN GC MS STRATEGIES AND METHODOLOGIES FOR PCDD AND PCDF ANALYSIS .1. EVALUATION OF THE NONPOLAR DB-5MS COLUMN, Fresenius' journal of analytical chemistry, 348(1-2), 1994, pp. 154-158
The analysis of polychloro-p-dibenzodioxins (PCDD) and polychlorodiben
zofurans (PCDF) on a new non-polar column, DB-5ms, is reported. This n
ew 5% phenyl column exhibits identical inertness, sensitivity, stabili
ty and capacity to DB-5 for PCDD and PCDF but provides better separati
on for some toxic 2,3,7,8 substituted congeners. Linear response for l
abelled and unlabelled toxic congeners is easily obtained over the ran
ge from 0.5 pg to 200 ng for 2,3,7,8-TCDD.
