Over the last twenty years, SPE has become the most powerful technique available for rapid and selective sample preparation (prep) prior to analytical chromatography. SPE extends a chromatographic system’s lifetime, improves qualitative and quantitative analysis, and by changing an analyte of interest’s original matrix environment to a simpler matrix more suitable for subsequent analysis, the demand placed on an analytical instrument is considerably lessened. ![Solid phase extraction equipment](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/technical-documents/articles/analytical-chemistry/solid-phase-extraction/p001015.jpg "Solid Phase Extraction (SPE) Overview") ![Charts manifold](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/technical-documents/articles/analytical-chemistry/solid-phase-extraction/charts_manifold.jpg "Solid Phase Extraction (SPE) Overview") ### Use SPE for Samples that - Contain particulate matter causing system clogging and high back-pressure - Contain components that cause high background, misleading peaks, and/or poor sensitivity - Require cleanup, trace enrichment/concentration, or purification - Require sample matrix or solvent exchange ### Benefits of SPE - Switch sample matrices to a form more compatible with chromatographic analyses - Concentrate analytes for increased sensitivity - Remove interferences to simplify chromatography and improve quantitation - Protect the analytical column from contaminants ### Common SPE Applications - Pharmaceutical compounds and metabolites in biological fluids - Drugs of abuse in biological fluids - Environmental pollutants in drinking and waste water - Pesticides and antibiotics in food/agricultural matrices - Desalting of proteins and peptides - Fractionation of lipids - Water and fat soluble vitamins __Related Articles__ - [Reversed-Phase SPE Methodology](https://www.sigmaaldrich.com/DE/en/technical-documents/protocol/analytical-chemistry/solid-phase-extraction/reversedphase-methodology) - [Ion Exchange Methodology](https://www.sigmaaldrich.com/DE/en/technical-documents/technical-article/analytical-chemistry/solid-phase-extraction/ion-exchange-methodology) - [Ion-Exchange SPE Methodology](https://www.sigmaaldrich.com/DE/en/technical-documents/technical-article/analytical-chemistry/solid-phase-extraction/normalphase-methodology) - [Determination of Formaldehyde and Acetaldehyde in Air Using DNPH Cartridges and Automated On-Line Desorption Followed by HPLC](https://www.sigmaaldrich.com/DE/en/technical-documents/protocol/environmental-testing-and-industrial-hygiene/air-testing/aldehydes-air-dnph) - [Effect of Container Materials on Milk Off-Flavors](https://www.sigmaaldrich.com/DE/en/technical-documents/technical-article/analytical-chemistry/gas-chromatography/container-materials) - [Pesticide Residue Analysis in Ginger Powder with QuEChERS](https://www.sigmaaldrich.com/DE/en/technical-documents/technical-article/analytical-chemistry/quechers/analysis-of-pesticide-residues-in-ginger-powder) - [Analysis of Pesticide Residues in Pistachios Using QuEChERS Extraction and Cleanup with Supel™ QuE Z-Sep+](https://www.sigmaaldrich.com/DE/en/technical-documents/technical-article/analytical-chemistry/quechers/analysis-of-pesticide-residues-in-pistachios) - [HybridSPE-Phospholipid Technology](https://www.sigmaaldrich.com/DE/en/technical-documents/technical-article/analytical-chemistry/small-molecule-hplc/hybridspe-precipitation-technology) - [View More](https://www.sigmaaldrich.com/DE/en/search/facet-search?focus=sitecontent&term=facet-search) Oben __Melden Sie sich an, um fortzufahren.__ Um weiterzulesen, melden Sie sich bitte an oder erstellen ein Konto.
