Chromatography is the science of separating molecules of interest to identify, quantify or even purify them. Properties of the target molecules such as their solubility, size or hydrophobicity give ...

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 ...

Rising drug costs have increased public pressure on the biopharmaceutical industry to find ways to identify and eliminate high-cost unit operations. Biopharmaceutical manufacturing groups now ...

Sample preparation makes up approximately 60% of the ion chromatography workflow. Due to the unique ion exchange mechanisms and separation chemistry of analytes, it’s important to understand how ...

When ion-exchange chromatography and mass spectrometry are coupled using electrochemical ion suppression, it allows for the selective and specific analysis of highly polar and ionic compounds. The ...

Ionic and ionizable compounds typically rely on separation by ion exchange chromatography (IC) or ion pairing reversed-phase chromatography (IP-RPLC). In traditional Reverse-phase Liquid ...

Alfa Chemistry has grown its product line to meet the vital demand for advanced separation technologies by introducing regular ion exchange resins, specialty ion exchange resins, and ion exchange ...

CHARCOAL has been used widely for selective adsorption of nucleotides from reaction mixtures and tissue preparations. In experiments reported here three commercially available grades were all found to ...
