Le choix d’une méthode de séparation constitue une étape essentielle dans la mise au point de toute analyse par Chromatographie . Le fait, pour le chromatographiste, de disposer aujourd’hui d’un vaste éventail de méthodes et, à l’intérieur de celles-ci, d’une large gamme de phases stationnaires, ne simplifie pas ce choix, alors même qu’il présente, par...

Imad Haidar Ahmad and colleagues at Merck present multifactorial peak crossover (MPC)—a new technique to quickly isolate peaks of interest. Using computer-assisted chromatographic modelling, the separation landscape is mapped and conditions that change peak-elution orders are found. Peaks of interest can be quickly shifted to convenient areas of the chromatogram, dramatically reducing the time spent...

In LC Method Development I to III, we covered the key points of method development: figuring out the project purpose, choosing parameters for screening, and optimizing. How do you assemble all these components into one workflow and manage them efficiently? This webinar puts it all together by showing you how to manage your projects from...

Optimized LC methods give the results you need to satisfy customers, synthetic chemists, QC teams, and other end users. Compared to trial and error, a proper optimization process saves time and resources. And with optimization software, you can get even more efficient. In this webinar, we’ll cover the principles you need to know for method...

Method development is a journey into the unknown. The destination may be clear enough, if you’ve defined your project goals. But unforeseen challenges lurk to trip up the unwary chromatographer. Before you know it, your two-week project has become a six-week odyssey, with events like: “Where did my compound go?” “Why are my peaks lopsided?”...
