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).
Collaboration to explore FAIMS with TOF-MS
June 5th 2009Owlstone Nanotech and Agilent Technologies have announced a phase one agreement to develop Owlstone's field-asymmetric ion mobility spectrometry (FAIMS) filter as a front-end separation module for Agilent's Accurate Mass time-of-flight mass spectrometers (TOF-MS).
