Characteristics of PowSepu ORG Series Chromatographic Columns
The packing material of the PowSepu ORG series chromatographic columns is made from ultra-pure spherical fully porous silica gel with extremely low metal content as the base. The unique bonded sealing technology significantly increases the ligand coverage on the silica gel surface and effectively eliminates the impact of unreacted silanol groups in separation. Higher ligand coverage can greatly improve the inertness, separation capability, and stability of the packing material, making it an ideal chromatographic column for separating acidic, alkaline, and various organic compounds, with an exceptionally long service life.
PowSepu ORG C18 Chromatography Column
The PowSepu ORG C18 chromatographic column is not only suitable for detecting complex matrix samples in the food industry but also ideal for applications in other sectors, such as the analysis of traditional Chinese medicinal herbs and pharmaceutical intermediates. As a versatile column, it is widely applicable for the separation of acidic, alkaline, and various organic compounds.
