Application Note : 003

Title of application :
Determination of Boron

Area of application :
Water Analysis

Conditions :

Buffer CE-Boric acid kit
Sample 1. Cl-; 2. Br-/NO2-; 3. NO3-; 4. SO42-; 5. F-; 6. PO43-; 7.CO32-; 8.Boron (5ppm)
Capillary 50mm ID, 35 cm Length
Injection mode Hydrodynamic injection for 30 seconds at height of 10 cm
Separation setting -7kV
Instrument used CE-P1 

Description :
CE-P1 provides a rapid and sensitive method for determination of Boron in natural water.  No sample pre-treatment is required.  No interference from other common anions, such as chloride, nitrate, sulphate and carbonate are observed.
As high level of boron is toxic, it is a required testing item for natural water analysis.  The traditional methods, such as colorimetric determination by carminic acid and potentiometric determination are labour intensive and quite tedious.
