Shodex size-exclusion chromatography tutorial

This video provides a general overview of size-exclusion chromatography.Size-exclusion chromatography is used for analysing high molar mass compounds, such as synthetic polymers, bio-polymers, like proteins and antibodies, polysaccharides and...

Shodex ion chromatography tutorial

This video provides a general overview of ion chromatography.

The IC separation is based on electrostatic interaction (bonding) between the ion exchanger and ionic solutes. Different columns for anionic and cationic separation are available. The...

Accurate and reproducible water content determination by Karl Fischer titration

Water content determination is a standard application in many samples and Karl Fischer titration is the most widely used and accurate method. Metrohm offers solutions enabling the water content determination in almost any matrix ranging from...

Shodex ligand exchange chromatography tutorial

This video describes the separation mode of ligand exchange (LEX). The main application is the complex analysis of sugars. The LEX columns always have a double separation mode. This means two different separation modes in one column. Ligand...

Shodex HILIC tutorial

This video provides a general overview of hydrophilic interaction chromatography, also known as HILIC.HILIC separation is based on hydrophilic interaction. HILIC uses the same solvent as with reserved-phase chromatography (acetonitrile / water /...

Shodex reversed-phase chromatography tutorial

In this video one of the most used separation modes -  the reversed phase is being described.

Preparative-scale chromatography solutions

Preparative-scale chromatography plays a critical role in applications where compounds must be synthesized, identified, isolated, purified, characterized, screened, and tested. Waters AutoPurification Systems offer scalable prep configurations,...

Developing, Testing and Troubleshooting Chromatography Method Transfer

The transfer of chromatographic methods occurs at many stages in the development and production of a product. In its simplest form, the method is moved from one laboratory to another within the same organization, holding all instrumental and...
