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 ...

We are thrilled to announce that the 37th International Symposium on Preparative and Process Chromatography (PREP 2025) will take place at the Pennsylvania Convention Center in Philadelphia, PA, from ...

Below we discuss best practices for column qualification, evaluate the effects of tubing length and diameter on HETP and asymmetry, and derive a scaling relationship for tubing dimensions. Our ...

The wide range of chromatographic techniques share one common aim: to separate a material into its components. A material, your sample, is dissolved in a solvent, called the mobile phase. This mixture ...

Green analytical chemistry is no longer a niche concept but a necessity in today’s environmentally conscious world. As the world becomes ever more conscious of environmental sustainability, science ...

Case in point: For more than a century, chromatography practitioners have been separating the components of chemical mixtures by using columns packed with various types of particulate matter. Recently ...

There is a growing demand for high purity chemicals within the technical, life science and fine chemical industries. As new synthetic routes are discovered and purity requirements increase, the demand ...

The 34th International Symposium on Chromatography (ISC 2024) will take place in Liverpool from 6th to 10th October next year. We are proud to be hosting ISC in the UK and especially in Liverpool ...

The biopharma industry is looking at continuous chromatography for sensitive molecules. Continuous processes continue to advance in bioprocessing. In downstream processing, continuous chromatography ...

For some chromatographers, their first inkling that high-performance liquid chromatography was going to be a big deal came in 1969. That year, they traveled to Las Vegas to attend the fifth in a ...

Column chromatography is a powerful separation tool for biopharmaceutical research and industry, with applications ranging from laboratory bench-scale purification to process development and ...
