Using the AF2000-autosampler “shaking option” for enhanced sample recovery of fast sedimenting samples using the example of titanium dioxide nanoparticles in sunscreens

This application note shows the separation of TiO2 nanoparticles of a model and a real sunscreen sample after extraction; two samples that are prone to fast sedimentation and thus significant sample loss and size discrimination already during the injection step. Therefore, the benefit of using the “shaking option” of the AF2000-autosampler is demonstrated.
