BEKOlut® PSA
PSA (Primary Secondary Amine) is similar to aminopropyl ( NH2) SPE phases regarding the selectivity, but offers a much higher ion capacity due to the presence of the secondary amine group. Besides the behaviour as polar SPE phase, PSA acts as an weakly anion exchanger and therefore removes fatty acids and organic acids when performing multi-residue pestcide analysis in foodstuffs. It is used in all dispersive QuEChERS kits for sample clean-up.
