的詳細(xì)介紹
IonPac ICE-AS1 Ion Exclusion Column
Ion-Exclusion Column for Fast Analysis of Aliphatic Organic Acids and Alcohols in Complex Samples
The IonPac? ICE-AS1 ion-exclusion column provides fast analysis of aliphatic
organic acids and alcohols in complex or high-ionic-strength samples,
including foods and beverages, biological samples, fermentation baths,
industrial process liquors, and wastewaters.
-
Fast separation of organic acids
-
Ideal for electroactive ions such as cyanide and sulfite
-
Useful for organic acids and alcohols in complex sample matrices
The
IonPac AS11 is recommended for fast analysis of organic acids and
inorganic anions in well-characterized samples. Use the high-capacity
IonPac AS11-HC for organic acids and inorganic anions in complex sample
matrices.
With the IonPac ICE-AS1 column, 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 quantification of the organic acids. The ICE-AS1
column can be used with any typical strong acid eluent and a wide
variety of detectors, including conductivity, amperometry, photometry,
and refractive index, to determine aliphatic organic acids.
Note: Use the Anion MicroMembrane? Ion-Exclusion Suppressor (AMMS? ICE 300) with the ICE-AS1 column.
