的詳細介紹
IonPac AS21 Hydroxide-Selective Anion-Exchange Column
For Fast Analysis of Trace Perchlorate in Drinking Water Prior to Detection with MS/MS
The
AS21 hydroxide-selective anion-exchange column is specifically designed
for determination of trace perchlorate in drinking water prior to MS/MS
detection. The capacity and selectivity enable fast analysis of
perchlorate at low μg/L concentrations. The AS21 is the specified column
in US EPA Method 331.0.
-
Fast separation of perchlorate prior to MS/MS detection
-
Optimized for methylamine or hydroxide mobile phases
-
Specified column for US EPA Method 331.0
-
Optimum capacity: 45 μeq per column (2 × 250 mm)
-
Operates at ambient or elevated temperatures
-
Compatible with organic solvents
The
AS21 2 × 250 mm column format was specifically developed for MS/MS
compatibility to allow use of volatile mobile phases such as
methylamine.
