Acclaim®混合基質(zhì)WAX 色譜柱是一款硅膠基質(zhì)固定相,同時具有疏水性和弱陰離子交換能力能力。能同時分析酸,堿,中性物質(zhì)。調(diào)整流動相能調(diào)節(jié)特定被分析物的選擇性 Reversed-phase and weak anion-exchange properties on a single column The novel column chemistry of the Acclaim Mixed-Mode WAX-1 results in a multimode separation mechanism including hydrophobic, anion-exchange, and cation-exclusion interactions.Consequently, retention of basic, neutral, and acidic molecules can be either independently or concurrently adjusted by changing ionic strength, pH, and organic solvent content in the mobile phase. ? Adjustable selectivity ? Selectivity orthogonal to reversed-phase (RP) columns ? Ideal selectivity for anionic molecules ? Simultaneous separation of acidic, basic, and neutral molecules ? Multimode retention mechanisms: reversed- and normal phase, anion-exchange, cation-exclusion, and HILIC modes
The Acclaim Mixed-Mode WAX-1 column combines hydrophobic and anion -exchange characteristics, on a 5 μm high-purity,porous silica with 120-? diameter pores. Because of this unique chemistry, the Acclaim Mixed-Mode WAX-1 column also provides complimentary selectivity to C18 reversed-phase columns.
Hydrophilic organic acids are often difficult to separate with common RP columns, since hydrophobic retention alone is inadequate to differentiate molecules with similar hydrophobicities.This can be overcome using the Acclaim Mixed-Mode WAX-1 column; it provides sufficient retention, and ideal selectivity for a variety of anionic molecules, even for weakly charged molecules.
