的詳細(xì)介紹
OmniPac PCX-100 Cation-Exchange Column
Cation-Exchange Column for the Separation of Low-Molecular-Weight Species
The OmniPac? PCX-100 column is a microporous, solvent-compatible, high-capacity,
cation-exchange column designed for the separation of hydrophobic
cations, such as amines, drugs, and metabolites.
-
Acid, base, and solvent compatible, pH 0–14
-
Good for organic cations
-
Ideal for the separation of very hydrophobic cations
-
Good for the separation of halogenated cations
The
OmniPac PCX-100 column is a specialty cation-exchange column for the
separation of low-molecular-weight cations, especially organic analytes.
Group 1A and 2A inorganic cations are best separated on the IonPac CS12A column, which is also solvent compatible. The OmniPac PCX-100 column is
100% solvent compatible and should always be run with at least 1%
organic solvent in the mobile phase.
The OmniPac PCX-100 is
manufactured using a microporous substrate agglomerated with a
sulfonated latex bead layer that carries the cation-exchange
functionality. The cation-exchange layer is the same as that used in the
OmniPac PCX-500 column, and consequently the ion-exchange
characteristics of these two columns are identical. The OmniPac PCX-100
column can be used to separate hydrophobic cationic analytes such as
amines, anilines, antidepressants, drugs, and metabolites (such as
methotrexate and folic acid).
