SPE Extraction Of Oil & Grease From Water Using SiliaPrep™ C18 (17%)
This document describes a method for the extraction of Oil and Grease from water samples using SiliCycle SiliaPrep™ C18 SPE cartridges. This technique is based on hydrophobic retention of the sorbent for the interfering components. Analysis of the cleaned sample can be done using LC-MS or GC-MS analytical technique .
This is a recommended general method using the SiliaPrep Reversed-Phase C18. You will find below tips for the choice of solvent that you should use to establish your SPE method development:

SiliaPrep™ SPE Cartridges C18 nec (23%)
SiliaPrep C18 is a non-polar sorbent used to extract acidic, neutral and acidic compounds from aqueous solutions, various organic compounds from water as well as drugs & metabolites from physiological fluids and various compounds from water, foods & beverages. Presence of free silanols allows secondary interactions for the extraction of basic compounds.

SiliaPrep C18 is a non-polar sorbent used to extract acidic, neutral and acidic compounds from aqueous solutions, various organic compounds from water as well as drugs & metabolites from physiological fluids.
-
SiliaPrep™ SPE Cartridges C18 nec (17%)
SiliaPrep C18 nec is a non-polar sorbent similar to SiliaPrep C18 but presents higher retention and polar selectivity for basic compounds. Unreacted surface OH's can be used for soft condition of catch and release purification of glucoronides for example.

SiliaPrep™ SPE Cartridges C18 (11%)
SiliaPrep C18 (11%) is a non-polar sorbent used to elute very large hydrophobic molecules that are too strongly retained on higher carbon loading.
-
SiliaPrep™ SPE Cartridges C18 nec (11%)
SiliaPrep C18 (11%) is a non-polar sorbent used to elute very large hydrophobic molecules that are too strongly retained on higher carbon loading. Use this less retentive phase for a rapid release of hydrophobic compounds using weaker organic solvents at lower volumes.
