的詳細介紹
Dionex IonPac AS16 Hydroxide-Selective Anion-Exchange Column
High-Capacity Column Optimized for Determination of Polarizable Anions
The
Thermo Scientific? Dionex? IonPac? AS16 column is ideally suited for
trace perchlorate in drinking water in accordance with US EPA Methods
314.0 and 314.1 (Primary Method). The Dionex IonPac AS16 column
simplifies the determination of polarizable anions, including
thiosulfate, iodide, thiocyanate, and perchlorate using an isocratic
hydroxide eluent.
-
Separate hydrophobic anions (iodide, thiocyanate, and thiosulfate) in less than 20 min
-
Can be used for trace perchlorate in drinking water matrices
-
Ideal for polyvalent anions, including polyphosphates and polycarboxylates
-
Ultralow hydrophobicity allows fast analysis of polarizable anions
The
Dionex IonPac AS16 is a high-capacity, hydroxide-selective column for
the determination of polarizable anions in a variety of sample matrices.
Trace concentrations of perchlorate in drinking water, surface water,
and ground water matrices can easily be determined using a large-loop
injection. The Dionex IonPac AS16 column is available in three formats:
standard bore (4 × 250 mm), microbore (2 × 250 mm) and capillary (0.4 ×
250 mm). The capillary format 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. The Dionex IonPac AS16 capillary column is used in the second
dimension of the 2D-IC method for the analysis of trace perchlorate (sub
ppb) in drinking water.
Note: Also see the Dionex IonPac AS20,
with complementary selectivity for confirmation of perchlorate
identification when using EPA Method 314.1
