Study Results from Ghent University Update Understanding of Chromatography

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Science. According to news reporting from Ghent, Belgium, by NewsRx journalists, research stated, "Offline two dimensional liquid chromatography (LC) x capillary gel electrophoresis (CGE) and LC x (24) multiplexed-CGE methodologies were developed for the separation of oligonucleotides of therapeutic size. Both ion-pair chromatography (IPC) and ion-exchange chromatography (IEC) were studied as methods for the first dimension and single and multiplexed capillary electrophoresis methods in entangled polymer solutions were used for the second dimension separations."

The news correspondents obtained a quote from the research from Ghent University, "Electrokinetic and pressure injection were evaluated for the analysis of the collected LC fractions. The comprehensive separation was optimized with standard mixtures of poly adenosine, thymidine, cytosine and uracil homodeoxyoligonucleotides up to 35 bases long."

According to the news reporters, the research concluded: "Highly orthogonal methodologies and overall peak capacities of 6435 and 6993 for IPC x CGE and IEC x CGE, respectively, were obtained within a few hours analysis time."
