的詳細介紹
IonPac ICE-AS6 Ion-Exclusion Column
Ion-Exclusion Column for Aliphatic Organic Acids and Alcohols in Complex Samples
The IonPac? ICE-AS6 ion-exclusion column is designed for fast analysis of aliphatic
organic acids (including hydroxyl-substituted organic acids) and
alcohols in complex or high-ionic-strength samples, including foods and
beverages, biological samples, fermentation baths, industrial process
liquors, and wastewaters. The ICE-AS6 column is ideally suited for most
applications performed on the ICE-AS1 column.
-
Use the ICE-AS6 column for organic acids in complex sample matrices.
-
Use the ICE-AS1 column for the fast separation of organic acids.
The
ICE-AS6 column provides improved peak efficiencies and selectivity for
carboxylic acids and alcohols. The weakly ionized acids are separated by
pKa differences, size, and hydrophobicity. Strong acid anions such as
chloride, oxalate, and sulfate elute in the void and do not interfere
with the quantification of the organic acids.
The ICE-AS6 column
can be used with any typical strong acid eluent and a wide range of
detectors, including conductivity, amperometry, photometry, and
refractive index to determine aliphatic organic acids. Use the AS11 for
fast analysis of organic acids and inorganic anions in
well-characterized samples. Use the high-capacity IonPac AS11-HC column
for organic acids and inorganic anions in complex sample matrices or
uncharacterized samples.
Note: Use the Anion MicroMembrane? Ion-Exclusion Suppressor (AMMS? ICE 300) with the ICE-AS6 column.
