​Teledyne ISCO Chromatography Webinars

Automated Gradient Optimization

Live Webinar | Thursday, May 23, 2019 | 1:00 PM CDT
Speaker: Jack Silver, Application Chemist

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.

By the end of this webinar, we will have: 

• Reviewed method development techniques for chromatography
• Introduced a new technique to generate focused gradients for flash and preparative HPLC
• Discussed method development for chemists using synthetic and natural products

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.

What to Do When Things Go Wrong in Prep Chromatography

March 2019: In our chromatography webinar, we will focus basic troubleshooting methods that are applicable to all Prep Chromatography systems. We will also take a look at retention time variations and how to handle them. Plus, we will take a look at other possible errors, such as poor peak shape, split peaks, and ghost peaks.

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.

Purification Considerations for Peptides

October 2018: In this webinar, we will also explore the advantages of mass-directed peptide purification and using flash chromatography in the pre-purification of peptides.

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.
