​Teledyne ISCO Chromatography Webinars

Sample Loading and Preparation Techniques

Live Webinar | Tuesday, November 19, 2019 | 10:00 AM CST
Speaker: Todd Anderson​, Global Chromatography Specialist

Chromatography has developed so many stationary and mobile phase possibilities that making the right choice may seem difficult, but with a little research and proper technique you can determine the best phases for your purification.

Global Chromatography Specialist with Teledyne ISCO, Todd Anderson explains how with the right knowledge and equipment you can optimize efficiency, meet your purity needs and minimize sample loss and down time - saving both time and resources.

By the end of this webinar you will understand:

• Sample loading techniques
• Solvent matrix effects
• Sample preparation devices and techniques

​​​Focused Gradient Generator

September 2019: In this webinar Jack Silver, Application Chemist at Teledyne ISCO will explain how gradient calculations can save time, trouble and solvents, all while improving your chromatography, but there are limitations to the gradient calculation methods. Jack Silver will also introduce us to a new gradient calculation method and explain how to apply it to your projects.

​​​Automated Gradient Optimization

May 2019: We will be discussing how chemists use scouting gradients to evaluate reactions and compound purity. These scouting gradients can be used to determine an efficient focused gradient for the desired compound. Topics covered will include techniques to create purification methods from focused gradients, and we will describe a new method allowing calculation of a focused gradient from a scouting run.

ACCQPrep HP150 Introduction

April 2019: We introduce our newest product: the ACCQPrep HP150! This latest innovation in Preparative HPLC systems does not follow the traditional path of an analytical system, but rather is intuitive and eliminates the unnecessary and complex integration parameters found in many of the HPLC systems in today's market. Plus, the ACCQPrep HP150 can be customized to meet your high performance purification needs.

By the end of this webinar, you will learn:

• What the ACCQPrep HP150 is and how it was designed with the ease of a Flash system in mind.
• How our automation options can be used to increase unattended purification throughput.
• What the variable options are for sample loading which were created to meet your sample volume needs.
• How the Focused Gradient Generator can generate a focused gradient to purify your target compound.

Tips and Techniques to Optomize ELSD and MS Based Purification

February 2019: In our Chromatography webinar, we will discuss the benefits of ELSD as an alternative detection method to UV. We will also provide example of several applications and classes of compounds where ELSD may be useful, and how to choose and change different ELSD experimental parameters. Plus we will explain the advantages of our integrated ELSD options for the ACCQPrep and NextGen Chromatography lines.

Introduction to Flash Chromatography

January 2019: This webinar focuses on a comparison of HPLC and Flash Chromatography. We will look at both similarities and differences of these two processes, cover how to transition from TLC or open column chromatography to flash, and the associated advantages of flash. Lab managers and bench chemists involved in organic synthesis, where milligrams to grams of material need purified, or who are new to or not currently using flash chromatography will benefit from information covered in this webinar.

Basics of Prep HPLC

December 2018: In our Chromatography webinar “Basics of Prep HPLC," we will discuss what Liquid Chromatography and HPLC are, the differences between analytical & prep, and the basic method development of isocratic vs. gradient.

Other important topics to be covered include: effects of buffering and buffer choice for purification; injection solvent effects and solvent choices; solvent grade for prep and solvent selection; column care; and common trouble shooting techniques.

Green Solvent Solutions for Flash Chromatography

November 2018: The NextGen series of systems are designed with "Green" chromatography in mind. Its methods offer faster separations with improved gradient profiles resulting in less solvent used. These savings decrease our environmental footprint while maximizing lab efficiency in both time and cost savings. New Features on the NextGen including baseline correction allows for greener, safer solvents not typically used in chromatography.

In this webinar, we will discuss green chemistry in the context of developing methods including importance of stationary phase choice, alternate green solvent choices, and getting things right the first time. Finally, we will show examples of some of the system features on the NextGen and how you can use them to minimize environmental impact while maximizing purification efficiency.

Natural Product Purification

August 2018: Topics covered include: what to do before purification, “Wide-Polarity Range” chromatography, column screening using “Wide-Polarity Range” chromatography for method development, and specialty chromatography media for natural products including Sephadex, ion exchange, and polyamide resin. Although the topics discussed use automated chromatography systems, the techniques can be adapted to hand-packed columns. You will come away from this webinar with a better understanding of natural product purifications and how Teledyne ISCO can meet these needs.
