Compound: Lithium
Reverse Elution Order in Separation of Alkali Cation |
 |
Application Notes: Primesep C separates a mixture of inorganic cations, potassium, sodium, and lithium, by a combination of cation exchange and complex formation. The peak order is reversed on the Primesep C column compared to the order normally obtained on columns that rely on cation exchange alone. The mobile phase mixture of water, acetonitrile (MeCN, ACN) and ammonium acetate is compatible with UV and evaporative light scattering detection (ELSD).

Complex of Cations on Primesep C is Effected by Organic Modifier |
 |
Application Notes: Primesep C separates a mixture of inorganic cations, potassium, sodium, and lithium, by a combination of cation exchange and complex formation. The peak order is reversed on the Primesep C column compared to the order normally obtained on columns that rely on cation exchange alone. In addition, the elution order can be rearranged by simply changing the organic modifier in the mobile phase from acetonitrile to methanol. The mobile phase mixture of water, acetonitrile (MeCN, ACN) or methanol (MeOH) and ammonium acetate is compatible with UV and evaporative light scattering detection (ELSD).

Separation of Metal Ions on Primesep 100 Column |
 |
Application Notes: Primesep 100 separates the monovalent cations, lithium, potassium, and sodium, and the divalent cations, zinc, manganese, and calcium. The cations are resolved by cation exchange. The mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) is evaporative light scattering detection (ELSD) compatible. Application Analytes: Application Detection: |
