An Acetonitrile Free Chromatographic Methodology for Melamine Detection and Quantitation With SFC
June 26th 2009The global economic downturn, particularly the collapse of the automotive and associated industries, has caused an overall reduction in the demand for acrylonitrile. Since acetonitrile is obtained as a co-product in the production of acrylonitrile, the pharmaceutical, food, environmental, and chemical industries are experiencing an unprecedented acetonitrile shortage. This shortage has resulted in a sharp price increase, in some cases as much as 6-8 times; and the price is projected to remain high even after the production returns to normal.
British research council launches consultation
June 26th 2009The Biotechnology and Biological Sciences Research Council (BBSRC) is launching a consultation on Next Generation Sequencing Technologies. The council is seeking comments from individuals and organizations from the UK?s academic and industrial research community about the potential impacts that these technologies can have on research in biosciences.
Chemical company's Asian acquisitions
June 26th 2009Speciality chemicals group LANXESS AG has made two acquisitions in Asia. The company will acquire the chemical businesses and assets of Gwalior Chemical Industries for €82.4 million. LANXESS will also acquire the business and production assets of Chinese-based Jiangsu Polyols Chemical Co.
Study of drug quality in the Indian market
June 26th 2009India is an increasingly influential player in the global pharmaceutical market. A pilot study, conducted in two major cities in India, Delhi and Chennai, explored the proliferation of substandard and counterfeit drugs in the market and discussed how the Indian state and federal governments could improve drug regulation and regulatory enforcement to combat this.
Characterization of Polyacrylnitrile
June 26th 2009In this application note GPC is used to easily and reliably analyze the molecular mass distribution of industrially produced polyacrylnitrile (PAN). Since this GPC application uses DMF and a small amount of lithium bromide as mobile phase, it will work on a standard HPLC system without any modifications.
Approaches to Singleton Achiral Purification of Difficult Samples for Discovery Research Support
June 19th 2009Several approaches for purifying difficult samples more efficiently for discovery research support are mentioned in this paper. These approaches use mass triggered HPLC on various specialty columns.
Improving Chromatographic Performance by Using Freshly Delivered Ultrapure Water in the Mobile Phase
June 15th 2009The purity of the solvent used for the mobile phase is one of many factors affecting the quality of chromatographic data obtained from high-performance liquid chromatography (HPLC). A typical reversed-phase HPLC gradient elution requires equilibration of the column to the initial conditions with several column volumes of the weak (aqueous) solvent.
Thermodesporption/GC–MC analysis of ogranic emission
June 12th 2009In the automotive industry, thermodesorption is one of the approved testing methods identifying volatile and semi-volatile organic compounds in non-metallic car materials. Shimadzu combines thermodesorption system with GC–MS technology providing excellent precision and sensitivity?
Analysis of Albumin Proteins using ProSEC 300S Columns
June 12th 2009Albumins are found in animal tissue, blood plasma, in bacteria and in plants, and include many important proteins with key functions in the body. ProSEC 300S columns from Varian, Inc. are designed for protein analysis and may be used to investigate a wide range of globular proteins, including the albumins, by size exclusion chromatography (SEC).
