Thermal Desorption- Sensitivity, Versatility and Multiple Applications
October 12th 2016What is thermal desorption and how can it extend the capability of GC? In this podcast, you’ll hear the answers to these questions directly from Elizabeth Woolfenden, a leading expert on this sample introduction technique. As a co-founder of Markes International, widely acknowledged as the world leaders in TD, Elizabeth has been right at the heart of the development of thermal desorption, and will draw on her experience to highlight the scope of the technique, along with key technical innovations and emerging applications. So whether you’re new to TD and want a quick introduction, or an experienced analyst interested in hearing a personal perspective, don’t miss this unique opportunity to get the lowdown on thermal desorption from a major player in the area!
Disulfide Bond Mapping, Comparing Innovator and Biosimilar mAbs
October 11th 2016This application note describes a UPLC-MSE analysis of monoclonal antibody (mAb) disulfide bond. This study demonstrates that UNIFI-a compliance-ready software-is designed to support biopharmaceutical laboratories in performing fast peptide mapping and monitoring of mAb disulfide linkages.
A Basic Overview: Meeting the PIC/S Requirements for a Computerized System
October 6th 2016This whitepaper provides a summary of the impact of PIC/S, and compliance with the PIC/S document PE 009-12 “Guide to Good Manufacturing Practice for Medicinal Products Annexes“ Annex 11 Computerised Systems. It includes a high-level foundation to understand how pharmaceutical manufacturing companies are being regulated, what PIC/S means for common requirements across different countries, and how these requirements relate to expectations for data from computerised systems/electronic records.
Arsenic Speciation on Hamilton PRP-X100
September 1st 2016Analysis of arsenic species is made challenging due to diverse sample matrices. To circumvent these problems, an HPLC ICP-MS method has been developed. Resolution of arsenic compounds is achieved by ion exchange chromatography on a Hamilton PRP-X100 column, a 55% cross-linked polystyrene-divinylbenzene copolymer functionalized with quaternary ammonium anion-exchanger group.
