Conclusion
The new Rtx®-440 column is an excellent addition
to the selection of innovative columns available
from Restek. The column exhibits high thermal
stability and, for organochlorine pesticides, a
selectivity alternative to the Rtx ®-CLPesticides2
column. An Rtx®-440 column can be paired with
an Rtx®-CLPesticides2 column to ensure sub-10-
minute analysis times for organochlorine pesti-
cides, or can be used as a confirmation column,
with an Rtx® -5Sil MS or an Rtx®-CLPesticides2
column, for GC/FID analysis of PAHs.
Figure 3 Analyze 16 PAHs in 22 minutes, and resolve critical pairs, with an Rtx®-440 column.
