Application Note : 011
Title of application :
Analysis of cationic impurities in water
Area of application :
Water analysis
Conditions :
| Buffer | CA-002 |
| Sample | Water fortified with metal cations (Peaks: 1. potassium, 2. sodium 3. calcium 4. magnesium 5. Barium 6. strontium. 50 ppb each) |
| Capillary | 50 mm i.d, 38 cm length |
| Injection mode | Electrokinetic mode |
| Separation setting | 7 kV |
| Instrument used | CE-P1 |
Description :
Ionic impurities in water have a detrimental effect on many industrial
processes. Examples are K+ and Na+ in fabricating circuit boards and
Ca2+ and Mg2+ in operating high pressure boilers. CE-P1 can be
employed as a useful means to generate a precise ionic profile, both peak identification
and quantitation, of a purified water sample.
