Characterisation of Non-Ionic Surfactants

In this talk, we will show characterization of ethoxylation in non – ionic surfactants. In the first dimension the separation is by degree of ethoxylation, while in the second dimension by the separation occurs by the length of the hydrophobic tail. This makes identification and quantitation possible in a single run. Using Agilent 2D LC MassHunter 11 software coupled with the G6230A Accurate Mass Time of flight instrument. We have both quantitative and qualitative data. We can show ppb levels of quantitative detection with Personal Compound Database Library (PCDL) matching in a Walkup environment that a plant QC technician can use.

Boost your Performance with 2D-LC Separation

This scientific presentation is for analytical chemists, chromatographers, and mass spectrometrists that want to learn, how an additional chromatographic dimension can deliver deeper insights into their samples, particularly when integrated with a mass selective detection system.

Several concepts of the different types of 2D-LC will be explained to enable a comprehensive understanding of this well-established technology.

The benefits of comprehensive Multiple Heart-Cutting, High-Resolution Sampling 2D-LC and the unique technique of Active Solvent Modulation will be explained in detail. Real-life examples will be shown to illustrate the advantages that incorporating an additional separation dimension brings to LC and LC/MS analysis.


What you will learn

•    First principles of 2D-LC technology
•    How to configure a mass detector with 2D-LC
•    How 2D-LC technologies enhance the quality of MS detection
•    Where 2D-LC makes a positive difference with several application examples
