One way they can do this is to use a process called chromatography. In the activity below, you can try chromatography to separate colors in a mixture of food coloring! Place a coffee filter on a tray ...

There is filter paper in a filter funnel above another ... For example, pure ethanol boils at 78°C and pure water boils at 100°C. Paper chromatography is a method for separating dissolved ...

Thus we conclude that spin filter-based approaches are subject to substantial losses of identifications at low sample loads, probably owing to binding of proteins and peptides to the spin filters.

The Zeta Plus™ encapsulated system is a single-use depth filtration system designed for the bioprocessing industry where upstream cell ...
