PSA (N-propylethylenediamine-substructio SPE columna)
Overview:
PSA est ethylenediamine-N-propyl extractio columnae cum silica gel, et PSA habet duos circulos amino, et pKa est 10.1 et 10.9 respective. Selectivity is similar to amino. Pro phase positivo vel anti-phase columna, verticitas fortior est quam C18 et debilior quam gel silica, et variae compositiones cum amplitudine mediae polaritatis vel polaritatis in diversis systematibus bonam selectivam habent.
PSA adhiberi potest cum metallis ad extrahendas metalla. Saepe in praeparatione exempla residua agriculturae, acida inclusa, pigmenta, metalla et phenola adhibentur.
