In this webinar, we will present previous guidelines regarding sample loading based on loop size and what our actual experiments showed in order to maximize sample loading volume without sample loss to waste. Also, we'll describe other tips to maximize injection efficiency and sample recovery. Finally, we will discuss how secondary methods of detection may be advantageous to various applications and things to consider when implementing.
The increased use of peptides as active site ingredients and Active Pharmaceutical Ingredients (APIs) necessitates improved purification techniques. This webinar will address how to handle impurities in synthesized peptides which often result from contaminants in the protected amino acid reagents and incomplete reactions as the peptide chain is lengthened.
This presentation discusses using a Flash system for routine purifications with the added convenience of having preparative HPLC capabilities. At times there are difficult separations where Flash simply does not have the necessary resolution. Other times compounds need purities in excess of 95% for library cataloging purposes.
Ron Lewis presents a webinar introducing the CombiFlash EZ Prep to Teledyne Isco's Chromatography product line.
Ron Lewis presents a webinar introducing the Automation Modules and how they can benefit customers that need to automate some of the mundane tasks involved with Flash and Prep chromatography.
Jack Silver presents a webinar on the use of alternative media in flash chromatography. To purify compounds, most flash chromatography relies on silica gel and high performance C18 columns. In unique circumstances, these types of columns do not adequately purify compounds and may require alternative column chemistries. This webinar discusses alternative chemistries and the required method developments.
Ron L. Lewis presents a webinar on Teledyne Isco's CombiFlash Rf+ PurIon Flash Chromatography and Mass Spectrometry system. This presentation outlines the benefits of mass-directed compound purification with the CombiFlash Rf+ PurIon.
Ron L. Lewis presents a webinar on solid versus liquid sample loading. Ron provides details on selecting the best loading technique for your sample and identifies potential pitfalls with each technique. This presentation is a practical session with examples of what works and what does not.
Ron L. Lewis presents the benefits of using C18 column media with reversed phase flash chromatography. Benefits include column reuse, higher loading, less solvent usage, and a smaller carbon footprint.
