Application Notes

• Analytical methods for semi-volatile organic compounds can be streamlined. • Small-volume extraction techniques offer benefits over large volumes. • New techniques reduce sample preparation time and labor requirements.

This application compares direct injection and online SPE methods for determination of microcystins in water. The achieved limits of detection are below WHO requirements.

This application describes a method to rapidly analyze 26 pesticide metabolites of different polarities in drinking water, with quantitation limits in the sub-ng/L range.

This application demonstrates the detection of trace-level PPCPs in environmental water by online SPE and compares the results with a direct injection approach.

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.
