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...
Activated carbon has a very high adsorption capacity, but the adsorption process is irreversible, making it difficult to elute the adsorbed substances. Welchrom Carb overcomes the irreversibility o...
Welchrom GraphiCarb/PSA is a mixed-layer SPE product composed of an equal amount of graphitized carbon black in the upper layer and PSA (Primary and Secondary Amine) in the lower layer. The upper g...
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 C8/SCX Mixed Mode SPE Product combines a C8 alkyl stationary phase and a strong cation exchange stationaryphase SCX on a silica matrix in an optimized ratio. This dual-phase composition pr...
