的詳細(xì)介紹
OmniPac PAX-100 Anion-Exchange Column
Anion-Exchange Column for the Analysis of Hydrophobic and Halogenated Anions
The OmniPac? PAX-100 column is a microporous, solvent-compatible, high-capacity,
anion-exchange column designed for the separation of hydrophobic anions,
and specifically very hydrophobic and halogenated anions. All neutral
matrix components are eluted in the void volume.
-
Acid, base, and solvent-compatible, pH 0–14
-
Well suited for the separation of high-molecular-weight organic acids
-
Good for the separation of very hydrophobic anions
-
Good for the separation of halogenated anions
The
OmniPac PAX-100 column was one of the first solvent-compatible,
anion-exchange columns for the separation of inorganic and organic
anions providing acid and base compatibility over the entire pH range.
Because the OmniPac PAX-100 is solvent compatible, solvents can be used
to modify the ion-exchange selectivity. Additionally, solvents can be
used to solubilize otherwise insoluble samples, or to remove organic
impurities from the column to prolong column life. The OmniPac PAX-100
is 100% solvent compatible and should always be run with at least 1%
organic solvent in the mobile phase.
The OmniPac PAX-100 column is
particularly well suited for the analysis of larger organic acids,
including alkylbenzene sulfonates, aromatic acids, barbiturates,
polyphosphates, inositol phosphates, thiocyanate, thiosulfate, and
iodate. For separations of inorganic and low-molecular-weight organic
acids, the IonPac? AS11 and IonPac AS11-HC are suitable alternatives that may provide different selectivities. The
IonPac AS11 and AS11-HC may also be considered as viable alternate
columns for larger organic acid applications.
