ABSTRACT
In this webinar, you’ll learn how to address your lab’s purification pain-points with methods and instrumentation to maximize your budget, time and increase overall efficiency. During this session you will discover:
How to select the ideal purification solution for your lab’s specific needs
How to optimize your purification workflow daily, to automate compound ID and fraction confirmation – using simple, prep free tools
How your cell phone can be used for automated method development
How column selection factors in to your workflow, and why exploring what is best for your method matters
In this application note, we use whey protein isolate and two casein macro peptides as an example to demonstrate the isolation and purification of bioactive peptide components with a system comprised of a puriFlash® 5.250 prepLC coupled online to an expression® CMS detector.
The expression® CMS (Compact Mass Spectrometer) is the ideal instrument for the teaching lab thanks to its small size, ease of use, and one-click software. This pocket guide of classroom experiments offers students the ability to gain hands-on instrument experience by eliminating complex and difficult sample preparation.
In this application note, we demonstrate a complete solution for the synthesis, purification, and quantitation of Gd(III)-DOTA, an ionic imaging contrast agent with better chemical stability and lower toxicity compared to the currently used Gd-(DTPA).
In this application note, we show how Cyanidin-3-glucoside can be extracted from black rice and purified with a prepLC/Flash system. The amount and purity of Cyanidin-3-glucoside was measured utilizing a certified reference standard.
In this application note, a method to separate and purify green tea catechins with preparative liquid chromatography (Prep-LC) using the puriFlash® 5.250 system is demonstrated. An additional HPLC-UV-MS method is also demonstrated for compound confirmation and purity analysis.
In this application note, a method to separate and purify 3 curcuminoids from turmeric powder using thin layer chromatography (TLC) with mass spectrometry and flash chromatography is demonstrated.
In this application note, we describe methods of isolating natural products from green tea and turmeric powder by mass-directed fraction collection during flash chromatography and preparative LC. For demonstration purposes, the isolated compounds were then additionally confirmed by Atmospheric Solids Analysis Probe (ASAP®) MS or HPLC-MS.

Ask the Expert Webinar
Presented live November 2, 2022
Step inside the Parasram Lab at New York University for a look at some of their latest research.
In this webinar, Professor Marvin Parasram will discuss data from his laboratory’s recent publication, “Anaerobic Heteroatom Transfer Reactions Using Photoexcited Nitroarenes.” The research features developments on the anaerobic cleavage of alkenes into carbonyl compounds using nitroarenes as oxygen transfer reagents under visible light. This approach is a safe and practical alternative to mainstream oxidative cleavage protocols, such as ozonolysis and the Lemieux–Johnson reaction.
As an attendee, you will learn more about:
How a wide range of alkenes possessing oxidatively sensitive functionalities underwent anaerobic cleavage to generate carbonyl derivatives with high efficiency and regioselectivity, using the Advion Interchim Scientific puriFlash® 5.250 Preparative HPLC system.
Mechanistic studies support that the transformation occurs via direct photoexcitation of the nitroarene followed by a nonstereospecific radical cycloaddition event with alkenes.
How this process leads to 1,3,2- and 1,4,2-dioxazolidine intermediates that fragment to give the carbonyl products, using the Advion Interchim Scientific expression Compact Mass Spectrometer.
How a combination of radical clock experiments and in situ photoNMR spectroscopy revealed the identities of the key radical species and the putative aryl dioxazolidine intermediates, respectively.Watched the video and ready to learn more?
