This anion column line is designed to meet the special requirements of anion analysis. These four columns cover all aspects of standard anion analysis, separation of all 8 common anions in one run. The unique design of the highly cross-linked porous-packing material, and the strong covalent bonded surface chemistry, ensure excellent durability and high separation efficiency. These columns are designed to be used with carbonate-bicarbonate buffer in any concentration or with hydroxide gradient, and many other mobile phases.

• Analysis of common anions in aqueous solutions
• High resolution separations
• Rigid polymer support for pressure stability up to 350 bar
• Can be used with 0 to 100% organics and at pH 1 to 13
• Compatible with any Ion Chromatograph or HPLC system
• PEEK hardware for biocompatibility

Anion Resolution
- High resolution column with high separation efficiency
- High sample-loading capacity
- Analysis of low and high ion concentrations in a single run

Anion Fast
- For fast separation of all common anions under 15 minutes
- Well-balanced ratio between good resolution and short analysis time
- For medium and low sample concentrations from 1 to 500 ppm

Anion Micro
- High resolution of common anions
- Ideal for separating/isolating limited sample amounts
- Can be used with micro pumps at low flow rate in the μl/min range

Anion Trace
- Separation of common anions and oxihalides
- Improved signal-to-noise for analysis of very low concentrations in ppb range
- Improved peak shape and shorter retention times for late eluting anions
