的詳細(xì)介紹
Thermo Scientific Dionex IonPac AS11-HC Hydroxide-Selective Anion-Exchange Column
For Resolving a Large Number of Inorganic Anions and Organic Acid Anions in Complex Matrices
Complex
sample matrices such as chemical wastewater effluents and fermentation
broth solutions contain a variety of inorganic anions and organic acids.
The Thermo Scientific* Dionex* IonPac* AS11-HC column was specifically
designed to resolve a large number of inorganic anions and organic acid
anions in a single run using a hydroxide gradient. The new Dionex IonPac
AS11-HC Capillary Column is packed with the same material as the
equivalent standard bore and microbore versions (providing the same
performance as a 4 mm and 2 mm column) but requires only 1/100th the
eluent flow rate. The capillary format provides the advantage of
significantly reduced eluent consumption, which helps reduce operating
costs
-
Use for organic acids and anions in complex sample matrices or uncharacterized samples.
-
Recommended for monovalent and divalent organic acids.
-
Use the Dionex Ionpac AS11 for fast analysis of organic acids and anions in well-characterized samples.
-
Use the Dionex IonPac ICE-AS1 or ICE-AS6 columns for organic acids in high-ionic-strength samples.
-
High capacity translates into longer retention times, but with higher resolution.
The
high-capacity Dionex IonPac AS11-HC column allows the injection of more
concentrated samples without column overloading or peak broadening, and
provides improved separation over the Dionex IonPac AS11 column for
monovalent carboxylic acids, including quinate, lactate, acetate,
propionate, formate, and butyrate.
