The CleanX PSA SPE Cartridges are packed with ethylenediamine-N-propyl (PSA) sorbent, featuring two distinct amino functional groups that provide higher pKa and ionic capacity than traditional NH₂ phases.This dual functionality enables strong anion exchange, polar adsorption, and chelation capabilities—making it exceptionally versatile for removing organic acids, pigments, metal ions, and phenolic compounds.CleanX PSA is widely used in pesticide residue analysis and food testing, where efficient matrix cleanup and high recovery rates are critical for accurate detection and quantification.The CleanX PSA sorbent provides enhanced ion-exchange capacity through its dual amino groups, allowing simultaneous removal of acidic and metallic impurities.Its chelating capability makes it ideal for sample purification prior to pesticide and contaminant quantification, especially in complex agricultural matrices.By reducing background interference and color pigments, CleanX PSA helps achieve cleaner chromatograms, improved accuracy, and reliable quantification in modern analytical laboratories.
