Organic Geochemistry Research Laboratory
Solid-Phase Extraction (SPE)
Solid-phase extraction is used for the majority of the methods
at the Organic Geochemistry Research Laboratory (OGRL).
SPE extractions are performed in the OGRL as follows:
- Manual extraction on a vacuum manifold.
- Autotrace extraction workstations which automatically
prepare the cartridge, load the sample and elute off the extract.
- Online extraction which elutes automatically and the extract is injected directly to the Liquid Chromatograph/Mass Spectrometer.
- Accelerated Solvent Extractor for soil extraction.
