Welch guard cartridges use the same packing materials as the analytical column to ensure the best analysis results. When HPLC column ID<4.0mm, it is recommended to use a 2.1×10mm cartridge, whil...
WH Fine Series couple functional groups to a rigid agarose matrix for enhanced resolution (compared to WH Series), ideal for intermediate or final purification steps.
Welch preparative guard column cartridges use the same packing as the preparative column, which can intercept some of the same polar substances in the sample and prevent them from contaminating and...
WA-Ni is a metal affinity chromatography resin pre-charged with Ni²⁺ ions on agarose gels functionalized with NTA, IDA, or TED chelators. It features high binding capacity, excellent selectivity, e...
WA-GST Series consist of glutathione covalently bound to highly cross-linked agarose. Designed for the specific purification of glutathione S-transferase (GST) and GST fusion proteins, these resins...
Welchrom ion chromatography columns utilize high-purity packing materials and employ the principles of reverse-phase adsorption and ion exchange to effectively remove impurity ions, organic compoun...
