Application Note : 004

Title of application :
Determination of anions in mineral water

Area of application :
Water Analysis

Conditions :

Buffer CE-AN001 Kit
Sample Mineral water acquired from the supermarket.
1. Cl- (3 ppm); 2. NO3- (1.2 ppm); 3. SO42- (2.5 ppm); 4. CO32- (80 ppm); 5. Unknown
Capillary 50mm ID, 35cm Length
Injection mode Hydrodynamic injection for 30 second at 10cm
Separation setting -7kV
Instrument used CE-P1 

Description :
CE-P1 can detect common anions in mineral water directly without the need of any sample pre-treatment.
The levels of common anions can reflect the quality of the mineral water.  This is especially true for the case of  NO2- and NO3- which are important parameters for monitoring bio-contamination of the water.
