FAQ of spe extraction
What ions can be removed using Na⁺, H⁺, Ag⁺, and Ba²⁺ columns?
Na⁺ / H⁺ columns: remove cations, adjust sample ionic strength
Ag⁺ columns: remove halide ions (Cl⁻, Br⁻)
Ba²⁺ columns: used for removing sulfates and certain heavy metals
What is a C18 SPE cartridge?
A C18 SPE cartridge is a type of solid phase extraction column packed with octadecylsilane (C18)-bonded silica particles. It is used to retain and isolate non-polar and moderately polar compounds from liquid samples. C18 cartridges are commonly used in environmental, pharmaceutical, and food analysis to remove interferences and concentrate analytes before further testing.
How to perform SPE (Solid Phase Extraction)?
To perform solid phase extraction, load the sample onto the SPE column, allowing analytes to bind to the packing material. Then, wash the column to remove unwanted matrix components. Finally, elute the target analytes using an appropriate solvent. This process concentrates and purifies the analytes for more accurate analysis.
What is liquid-liquid extraction?
Liquid-liquid extraction (LLE) is a separation technique that transfers a compound from one liquid phase into another based on solubility differences. It is commonly used to isolate analytes from complex mixtures by exploiting their differing affinities between two immiscible liquids (usually water and an organic solvent).
How does liquid-liquid extraction work?
In liquid-liquid extraction, the sample is mixed with a second immiscible liquid (e.g., water and hexane). The analytes of interest dissolve preferentially into one phase, while unwanted compounds remain in the other. After separation, the desired phase is collected for further processing or analysis.
