Most of the SPE cartridges seem to be designed for PAHs in waters which have different problems to soil extracts. Looking through the literature there seems to be a great deal of variety in cleanup procedures, some of which I find a bit dubious. The old EPA methods seem a bit dated and more appropriate for GC analysis. There are suggestions of NH2 SPE or just a C18 SPE for soil but if possible I want to avoid solvent exchange/blow down of the extracts.
Any suggestions or protocols would be welcome.
