Advances in Hydrophillic Interaction Liquid Chromatography for Pharmaceutical Analysis
Hydrophilic interaction liquid chromatography (HILIC) has recently become more important, particularly for the analysis of polar drugs, metabolites, and biologically relevant compounds in glycomics, proteomics, metabolomics, and clinical analysis. HILIC makes it possible to increase the retention of polar compounds, achieve orthogonal selectivity, and increase mass spectrometry (MS) sensitivity, compared with reversed-phase liquid chromatography. This article discusses the advantages and limitations of HILIC in a variety of practical applications in the pharmaceutical industry.
UltiMate 3000 Rapid Separation Systems
Developing and manufacturing drugs requires unique skills and extremely flexible LC instrumentation. Thermo Scientific’s UHPLC and HPLC-compatible Rapid Separation (RS, XRS, BioRS) systems not only offer exceptional workflow automation tools and unique detection technologies, but are truly designed around your laboratory workflows. With adjustable gradient delay volumes and powerful software tools, the UltiMate™ 3000 UHPLC platform gives you more data while requiring fewer resources and fewer experiments.
Assay for Parts-Per-Million Levels of Azide in Drug Substances
The removal of azide as a potential impurity from a drug substance may be critical to its safety profile, such that quantitation of this impurity becomes an important control parameter. This article describes a simple and practical assay for azide using chemical derivatization and high performance liquid chromatography. The method is shown to be suitable for the intended purpose on three example test materials. Potential issues for wider applications are discussed.

Solving One of Chromatography’s Biggest Dilemma — Proper Sealing of Chromatography Autosamper Vials — Using the Advanced Vial Closure System (AVCS)
Thursday, June 6, 2013
8:00 am PDT/ 11:00 am EDT/ 16:00 BST/ 17:00 CEDT.
This web seminar will review the impact an innovative vial & closure design, like AVCS, can have on improving data quality by providing data that supports how an AVCS-designed vial & closure eliminates under and over compression of vial seals while improving robotic autosampler pick-up of vials, ensuring more centered vial closure positioning and greater optical recognition of vials placed in autosamplers.
Multi-Residue Pesticide Analysis in Herbal Products Using Accelerated Solvent Extraction with Triple Quadrupole
Wednesday, June 25, 2013
8:00 am PDT/ 11:00 am EDT/ 16:00 BST/ 17:00 CEDT.
As the human population grows and farm acreage shrinks, the use of pesticides has increased, in order to produce food efficiently. Regulatory organizations are therefore requiring manufacturers to present test data on pesticide levels in food to address public safety concerns. Sensitive and robust routine screening methods to analyze hundreds of potential contaminants are therefore necessary.
