的詳細(xì)介紹
IonPac AS12A Carbonate Eluent Anion-Exchange Column
Fast Separation of Inorganic Anions, with Excellent Retention of Fluoride
The IonPac? AS12A anion-exchange column provides fast analysis of common inorganic
anions and oxyhalides, such as chlorite and bromate, in environmental
waters. This column is also useful for trace chloride and sulfate in
high-carbonate matrices.
-
Provides fast analysis of inorganic anions and oxyhalides at similar concentrations
-
Resolves trace chloride and sulfate high-carbonate samples
The
AS12A is a moderate-capacity, carbonate eluent anion-exchange column
designed for the fast, isocratic separation of inorganic anions and
oxyhalides, including fluoride, chlorite, bromate, chloride, nitrite,
bromide, chlorate, nitrate, phosphate, and sulfate in drinking water,
wastewater, groundwater, and other diverse sample matrices.
The
common inorganic anions and oxyhalides can be determined in less than 12
min using an isocratic carbonate/bicarbonate eluent coupled with
suppressed conductivity detection. It resolves chloride from high
concentrations of carbonate. Use the Anion Self-Regenerating Suppressor
(ASRS? 300) with the AS12A column.
Note: For trace
bromate in ozonated drinking water, use the high-capacity IonPac AS23,
recommended for determination of oxyhalides and inorganic anions.
