Specialist Products:

Zenix™ 3µm and SRT® 5µm SEC

Highest resolution and efficiency SEC in the market (High Resolution and lot-to-lot consistent alternative to TSK Super and SW series), made of proprietary uniform, hydrophilic, and neutral nanometer surfaced layered silica results in highly reproducible separation power for large molecule separation

Proteomix® IEX

A breakthrough technology of achieving combined high ion-exchange capacity and high resolution for the non-porous resins. With the particle size selection of 1.7, 3, 5 and 10µm, Proteomix ion-exchange phases are specially designed for high resolution, high efficiency and high recovery separations of proteins, oligonucleotides and peptides. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous particle.
NP1.7, NP3, NP5, NP10 with lot-to-lot consistent (alternative to Dionex) high resolution and high capacity phases available in SAX, WAX, SCX, and WCX. Ideal for protein, Oligo, Peptide, Carbohydrate, and etc applications

Antibodix™ WCX

Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
NP1.7, 3, 5, 10 for MAb separation (High Resolution lot-to-lot consistent performing alternative to Dionex Propac®).

Carbomix® Carbohydrate Analysis Column

Made of narrow-dispersed, spherical, low cross-linking polystyrene/divinylbenzene (PS/DVB) particles. Surfaces functional groups are sulfonic acid (-SO₃H), or metal ions, such as calcium (Ca⁺²). The PS/DVB support has cross-linking degree of 5%, 8% and 10%. The particle size selection is 3, 5 and 10µm for analytical and preparative separations of carbohydrates, organic acids, peptides, and nucleic acids.
Complete line for various carbohydrate separation needs. (High Resolution lot-to-lot consistent performing alternative to Bio-Rad Aminex line).
