The CleanX AI-N SPE Cartridges use a strong polar adsorbent with a neutral surface (pH 7.5), specially deactivated to avoid interference with analyte recovery during sample preparation.This balanced polarity makes it ideal for diverse matrices, allowing precise extraction of vitamins, antibiotics, aromatic oils, enzymes, glycosides, and hormones.AI-N exhibits excellent interactions with heterocyclic compounds (such as furagin and sulfur-phosphorus derivatives) and other organic molecules like m-cresol, propionic hydrocarbons, and amines, providing versatile cleanup for complex analytical samples.
