This is the third article in this series discussing HPLC oligonucleotide separations. Anion exchange chromatography can provide additional information when characterizing oligonucleotides. It can be ...

Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...

Ion exchange (IEX) chromatography is a technique that is commonly used in biomolecule purification. It involves the separation of molecules on the basis of their charge. This technique exploits the ...
