Countercurrent chromatography (CCC) is essentially a form of liquid-liquid partition chromatography in which the stationary liquid phase is retained in the apparatus without the use of a solid porous or adsorptive matrix. The principle behind this method of separation involves partitioning of a solute between two immiscible liquid phases, and the relative ratio of the amount of solute passing into each of the two phases is determined by the respective partition coefficient (K). A brief list of the main advantages of the technique includes versatility; speed; high loading capacity; good resolution; economy; predictability and reproducibility; and total sample recovery without chemical modifications or loss of biological activity in bioassay-guided fractionations.

After 24 years of the first Conference in London, CCC 2024 celebrates the researchers that are active in liquid-liquid partition chromatography to be together again after some years of the COVID-19 pandemics. This is the second time that CCC conference will take place in Rio de Janeiro, where researchers and students will have the opportunity to interact with expert professionals from around the world, providing participants with up-to-date knowledge in different areas of CCC. Aiming the creation of international partnerships, the participation of Latin American colleagues and encouraging networking, CCC2024 brings the novelty of the workshop “CCC in Latin America”, which will bring together researchers from these countries, showing the CCC community the excellent work carried out by research groups in these countries. The international meeting in the beautiful city of Rio de Janeiro, Brazil, will feature the latest developments in the fields of CCC/CPC research and applications. We hope to see you here!
