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.
