Simulated Moving Bed Chromatography- An advanced chromatography technique

Chromatographic processes play an important role in the production of bio-pharmaceuticals. Polypeptides, proteins, enzymes and antibodies are captured, purified and polished by ion exchange, size exclusion, reverse phase, hydrophobic interaction or affinity chromatographic processes. Their scales range from a few kilograms a year of very potent compounds to large bulk productions of several tons. Only recently research groups primarily from academics have started to investigate continuous operating technologies such as simulated moving bed chromatography (SMB) to increase productivity of purification processes for bio-pharmaceuticals…Read More


MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products. The new membrane-based system was developed by MIT postdoc Xiao-Yu Wu and Ahmed Ghoniem, the Ronald Crane professor of mechanical engineering, and is described in the journal ChemSusChem.The membrane, made of a compound of lanthanum, calcium, and iron oxide, allows oxygen from a stream of carbon dioxide to migrate through to the other side, leaving carbon monoxide behind.

Chemists at The Scripps Research Institute (TSRI) have invented a technique that overcomes a long-standing problem in organic chemistry and should streamline the process of discovery and development for many new drugs. The technique, known as ligand-accelerated non-directed C–H functionalization, is expected to find application not just in the pharmaceutical chemistry industry but also in a wide range of other chemical industries.However, it should be particularly useful for altering complex candidate drug molecules to find versions with optimal therapeutic properties.

Songwon Industrial Co Ltd said that it is increasing prices for the majority of its polymer stabilizers. The increase will vary depending on product type:

  • Antioxidants: 5 to 10 percent
  • UV absorbers and thioesters: 5 to 15 percent

The new prices will be effective from 1 December 2017. Read More
