Web2 Please inquire for pricing and availability of listed products to our local sales representatives. - Analysis is performed with pH adjusted to 7.5 with the addition of quaternary ammonium salts to the mobile phase. - Acidic samples form an electrically neutral ion-pair with the quaternary ammonium salt and are retained in the reverse phase
WebIon pair chromatography (IPC) is an effective reversed-phase liquid chromatographic (RPLC) technique for separation of organic ions and partly ionized organic analytes. The … Web15 jul. 2009 · A novel reversed-phase ion-pair liquid chromatography purification method that has the unique ability to separate blunt double-stranded DNA from pre-attenuated (n-1, n-2, etc) synthesis products, and from DNA duplexes with single base pair overhangs.
WebIon pair chromatography (IPC) is one technique used to separate charged substances. It is widely used to selectively analyze acids and bases, particularly with reverse phase … WebReversed-phase high-performance liquid chromatography (RP-HPLC) involves the separation of molecules on the basis of hydrophobicity. The separation depends on the hydrophobic binding of the solute molecule from the mobile phase to the immobilized hydrophobic ligands attached to the stationary phase, i.e., the sorbent.
