The Application Notebook-09-01-2019

Plastic micro- and nanoparticles are increasingly in the headlines, particularly when discussing marine pollution, but also with regard to their potential impact on human health. In this application note, we present data on separation of polystyrene nanoplastics, and demonstrate how electrical asymmetrical flow field-flow fractionation (EAF4) can be used for simultaneous size separation and particle surface charge measurement.

This application note describes the determination of the triphenylmethane dyes Malachite Green and Crystal Violet and their metabolites from the aquaculture samples brown trout, shrimp, and tuna using dispersive SPE (dSPE) with CHROMABOND QuEChERS mixes for sample clean-up.
