Solid phase extraction principle pdf
Overview Solid-liquid extraction or leaching generally refers to the removal of a component from a solid using a solvent liquid. The desired component, solute (A), is washed by the solvent (C) leaving the inert or insoluble solid (B) undissolved. Two phases result, the overflow, V, which is a clear solution of the solute and solvent and the underflow, L, which is the undissolved solid with
Solid phase extraction (SPE) is an extraction method that uses a solid phase and a liquid phase to isolate one (or one type of) analyte from a solution. The analyte is selectively adsorbed on the surface of the solid phase . Other solvent added to remove possible adsorbed matrix components (washing). Eluting solvent added to desorb analyte selectively. 3

Solid-phase microextraction (SPME), is a solid phase extraction technique that involves the use of a fiber coated with an extracting phase, that can be a liquid or a solid , which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid or gas phase.
Solid Phase Extraction To outline principles associated with choosing sorbent mass in SPE to optimise analyte recovery To explain the different steps in a Solid Phase Extraction protocol To fully explore each protocol step and investigate sorbent selection, eluent solvent strength optimisation and the use of pH and ionic additives to control selectivity in SPE To highlight specific issues
When the sample is a solid and the required phase for analysis is a liquid, the process is called solid-liquid extraction. A simple and broadly applicable form of solid-liquid extraction entails combining the solid with a solvent in which the analyte is soluble. Through agitation, the analyte partitions into the liquid phase, which may then be separated from the solid through filtration. The
