Welchrom non-silica-based inorganic SPE sorbents are commonly used as normal-phase polar sorbents. While they vary in polarity and surface pH, and thus have different applications, they are general...
Welchrom SAX/PSA is composed of two layers: the upper layer contains an equal amount of SAX (Strong Anion Exchange) material, and the lower layer contains an equal amount of PSA (Primary and Second...
Welchrom SAX (Strong Anion Exchange) is a strong anion exchange extraction column with quaternary ammonium functional groups bonded to the silica surface. It is primarily used for the adsorption an...
During HPLC analysis, especially when employing gradient elution, some unexpected peaks (usually called “Ghost Peaks”) may appear in the chromatogram. These unwanted peaks often coelute with analyt...
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...
WelFlash columns include a wide variety of amorphous silica, spherical silica, and inorganic sorbent packing materials, offering a diverse range of sample selectivity. The packing materials consist...
Welchrom mixed mode SPE cartridges are composed of adsorbents with various retention mechanisms packed in an optimized ratio. They combine the advantages of individual adsorbents to effectively add...
WM series capillary columns come with a complete range of stationary phases, including polydimethylsiloxane, cross-linked polyethylene glycol (PEG), and PLOTs, among others. Welch Materials offers ...
