PCBs from Soil Sludge or Cement

Summary

Type: SPE
Application #: 302040
Catalog#: 730109 - SPE Cartridges, Chromabond, NAN, 3ml, PP, 400/1400/400mg 50/pk
Detection:
Conditions: Conditioning: 2 ml n-hexane

Sample application: Slowly force or aspirate the extract of the sample
pretreatment through the column

Elution: Aspirate 10 ml n-hexane slowly through the column. Then concentrate to
5 ml.

To gain a better peak shape in GC a subsequent acetonitrile extraction is performed: Extract 2 ml of the n-hexane-extract with 2 ml acetonitrile.
After phase partition use ca. 1 ml of the acetonitrile phase for GC analysis.

Further analysis by GC with OPTIMA delta-6 (50 m x 0.20 mm ID, 0.2 mm film), Cat.No. 726465.50, as described in our application note 250480
