Hi-Purit™ NH2 SPE Cartridges are specialized solid-phase extraction (SPE) cartridges that use aminopropyl (NH2) functional groups as the stationary phase. These cartridges are commonly used in sample preparation for analytical chemistry, particularly for the extraction, purification, and concentration of analytes from complex matrices before chromatographic analysis.
Common Uses of Hi-Purit™ NH2 SPE Cartridges:
Cleanup of Polar Compounds:
Effective for retaining and separating polar compounds such as sugars, organic acids, amino acids, and nucleotides.
Extraction of Weak Acids and Bases:
The NH2 functional group acts as a weak anion exchanger, which can retain acidic compounds by ionic interaction.
Fatty Acid and Lipid Extraction:
Used to separate fatty acids and lipids from biological or environmental samples.
Removal of Matrix Interferences:
Helps in removing unwanted matrix components (like proteins, salts, or pigments) from samples such as biological fluids, food, or environmental samples.
