的詳細(xì)介紹
IonPac AS18 Hydroxide-Selective Anion-Exchange Column
For Determination of Inorganic Anions and Low-Molecular-Weight Organic Acids
The IonPac? AS18 anion-exchange column is the hydroxide-selective column of choice
for compliance monitoring of inorganic anions in drinking water and
wastewater samples in accordance with US EPA Methods 300.0 (A) and
300.1.
The new IonPac AS18-Fast columns offer the same
selectivity as the AS18 analytical scale columns, but with a reduced
length of 150 mm, these columns can separate the common inorganic anions
in significantly less time. The capillary format offers the advantage
of reduced eluent consumption, thereby lowering operating costs.
-
Fast separation of the common inorganic anions (4 min) using the AS18-Fast columns
-
Recommended hydroxide-selective column for inorganic anions in diverse sample matrices
-
Isocratic separation of common inorganic anions in 9 minutes
-
Inorganic anion and low-molecular weight organic acids in complex sample matrices
-
Superior retention and quantification of fluoride, acetate, and formate
-
Meets performance requirements specified in US EPA Method 300.0 (A)
The
IonPac AS18 column can determine inorganic anions and
low-molecular-weight organic acids in a variety of sample matrices. This
column has excellent retention of fluoride from the water dip. It is
approved for compliance monitoring of inorganic anions in drinking water
and wastewater samples in accordance with US EPA Methods 300.0 and
300.1. The AS18 column is now available in capillary format providing
the advantage of reduced eluent consumption, thereby lowering operating
costs.
