• Ion exclusion method is the best possible method for the separation of organic acid and alcohols.
• Zodiac provides a range of columns to select from, which result in varying efficiencies and selectivity for the separation of weak acids by ion exclusion.
• The Organic Acid columns are made of sulphonated polystyrene/ divinylbenzene (PS/DVB) cross-linked copolymer spherical particles which possess a negative charged. These negative charge of polymer particles plays a role in selectivity by adsorbing the compounds having no charge and allowing to enter into the spheres.

• Zodiac Carb USP L17 – The column is made of spherical, porous, polystyrene Divinyl benzene copolymer of 8.0% cross linkage, with sulphonyl functional groups and with particle size of 8mm.
• Zodiac Carb 87H – The column is made of spherical, porous, polystyrene Divinyl benzene copolymer of 9.0% cross-linkage, with sulphonyl functional groups and with particle size of 9mm.
• Zodiac Carb 67H – The column is made of spherical, porous, polystyrene Divinyl benzene copolymer of 6.7% cross-linkage, with sulphonyl functional groups and with particle size of 9mm.
• Zodiac Carb 64H – The column is made of spherical, porous, polystyrene Divinyl benzene copolymer of 6.4% cross linkage, with sulphonyl functional groups and with particle size of 9mm.

• Columns are packed with chemically very stable polymeric phases of PS/DVB.
• The varied percentage cross-linkage of copolymers and varied particle size gives choice of selecting required column.
• The temperature stability is exhibited by the columns up to 90 Degree C.
• The stable cross-linked polymeric phase gives sustainability throughout the pH range of 0 to 14.
• Excellent performance and consistency is guaranteed from column to column and batch to batch. Can undoubtedly achieve high resolution and high efficiency.
• Any required combination of cross-linkage, particle size or other column specifications can be provided on request.
