    Abstract: Treatment of anion exchange materials containing hydroxyl containing moieties in the beta position relative to the quaternary center in the hydroxide form with glycidol substantially alters the selectivity of the anion exchange material. Furthermore, sequential treatments of first a hydroxide containing solution to put the anion exchange material in the hydroxide form followed by treatment with glycidol in an alternating sequence progressively changes selectivity in a predictable manner allowing facile manipulation of selectivity. Unique to the selectivities achievable with this chemistry is the ability to reverse the elution order of sulfate and carbonate. With all other known systems, carbonate elutes ahead of sulfate and sometimes compromises the ability to quantitate sulfate. With glycidol treatment, carbonate can be moved after sulfate which eliminates interference issues for samples containing significantly more carbonate than sulfate. This modification is useful for columns operated with a hydroxide or carbonate eluent system.

    Abstract: Methods of forming a cobaltocenium-containing polymer are provided through polymerizing a plurality of cobaltocenium-containing monomers via controlled radical polymerization or controlled ring-opening polymerization. Each cobaltocenium-containing monomer comprises a cobaltocenium moiety covalently connected to a polymerizable group. Cobaltocenium-containing monomers are also provided that include a cobaltocenium moiety covalently connected to a polymerizable group. Cobaltocenium-containing polymers are also generally provided, such as the polymers formed according to any of the methods or from any of the monomers discussed herein. Methods are also generally provided for exchanging an anion associated with a cobaltocenium side group of a cobaltocenium-containing polymer with a new anion.

    Abstract: The present intimation relates to a method for purifying nucleic acids from a sample containing nucleic acids, the method comprising at least the following steps: a. bringing the sample containing nucleic acids into contact with a nucleic acid binding phase comprising protonatable groups, wherein the protonatable groups have a pKa value of 9 to 12; b. binding the nucleic acids to the nucleic acid phase at a pH (binding pH) that is at least one pH unit less than the pKa value of at least one of the protonatable groups; c. eluting the nucleic acids at a pH greater than the binding pH but at least one pH unit less than the pKa value of at least one of the protonatable groups. Also disclosed are corresponding kits and nucleic acid binding phases that can be used for purifying nucleic acids.
