Bond Elut PCB method?

Question

Hi, 
 
 I'm about to get some PCB samples that I'll need to extract and run on gcms. I currently have a method for the GC, but I was looking into the extraction method and noticed that agilent has a Bond Elut PCB cartridge. The site says that you can extract with only one solvent but doesn't give a method on what to use or procedure. There are two matrices, a filter and the water that the filter extracted from, and my standards are in iso-octane. Does anyone have a good method on how to extract these? I cannot do a Soxhlet extraction and was hoping for a SPE or Liquid/Liquid. Are these Bond Elut PCB cartridges just like the Florisil clean-up ones? 
 
 Thanks

HI crf, 
 the method with Bond Elut PCB is described here: https://doi.org/10.1016/S0378-4347(01)00447-9 
 A generic method is: 
 Sample preparation with Bond Elut PCB 
 Extraction of PCB&rsquo;s from an organic Matrix 
 I.e. waste oil or a hexane extract of an aqueous sample 
 
 Bond Elut - Cartridges: Bond Elut PCB 
 Catalog number: 1210-5032 
 
 Conditioning: apply 1 ml n-Hexane through the cartridge under light vacuum 
 Extraction: 
 1. Add 250 &micro;l sample solution to the extraction column 
 2. Add 1 ml n-Hexane 
 Elute slowly during 5 Minutes without vacuum 
 3. Add another 1 ml n-Hexane and elute the sample under gentle vacuum 
 4. Add and elute 3 x 0.5 ml n-Hexane under vacuum 
 5. Collect and combine the n-hexane fractions. 
 
 Adjust the desired concentrations of the combined fractions by evaporation under nitrogen or dilution with n-hexane.
