Based on liquid chromatography principles, SPE relies on strong, reversiple interactions, hydrophobic, polar, or ion exchange, between the analyte and stationary phase, where interactions with the matrix should not occur. \u003c\/span\u003e\u003cspan lang=\"EN\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"left\"\u003e\u003cspan lang=\"EN\"\u003eSample pre-treatment (e.g., adjusting pH or ionic strength) help maximize the chemical property differences between analyte and matrix, allowing the analyte to concentrate as a narrow zone on the stationary phase.
