Teknokroma introduces Finisterre™ Solid Phase Extraction (SPE) columns, designed to clean and concentrate samples quickly and efficiently before analysis by GC, HPLC, and other instrumental methods.
How Does Solid Phase Extraction (SPE) Work?
SPE is a technique used to isolate, concentrate, and purify analytes from a liquid sample before instrumental analysis. It operates through the following steps:
- Conditioning: The solid phase is activated with an appropriate solvent to enhance analyte retention.
- Sample Loading: The sample passes through the column, where the compounds of interest are retained on the solid phase.
- Washing: Impurities and contaminants are removed without affecting the retained analytes.
- Elution: The analytes are released from the solid phase using a suitable solvent for analysis in HPLC, GC, or other instrumental techniques.
Benefits of Finisterre™ SPE Columns:
✔ Efficient purification and concentration of analytes in solution.
✔ Enhanced sample purity, improving quantification and analytical accuracy.
✔ Extends the lifespan of HPLC columns by reducing contaminants.
✔ Cartridges allow selective adsorption and subsequent elution with the appropriate solvent.
Finisterre™ SPE: Optimize your analysis with precise and reliable sample preparation.
