General description

The ion-pairing reagents, when utilized as mobile phase additives, enable the elution of ionic and highly polar analytes on reversed phase HPLC columns. The purity of mobile phase additives is quintessential for their successful use. Sigma-Aldrich has a large collection of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) determinations. All mobile phase additives are rigorously examined with special focus on the necessities of modern reversed phase HPLC:

The encapsulation of metal clusters (Pt, Ru, Rh) within MFI was achieved by exchanging cationic metal precursors into a parent zeolite (BEA, FAU), reducing them with H2 to form metal clusters, and transforming these zeolites into daughter structures of higher

Zeolites play numerous important roles in modern petroleum refineries and have the potential to advance the production of fuels and chemical feedstocks from renewable resources. The performance of a zeolite as separation medium and catalyst depends on its framework structure.
