Q150t quorum coater

A Scanning Electron Microscopy (SEM) (Phenom-World B.V., Eindhoven, The Netherlands) was used in order to examine the morphology of the capsules produced by electrospraying. The capsules from different experiments were collected on the foil and kept in a desiccator in order to examine the effect of Asc and surfactant addition, as well as the use of different Microfluidizer passes. Approximately 0.5cm 2 of aluminum sheet covered with a thin layer of electrosprayed capsules was placed on carbon tape and sputter-coated with gold, 8s, 40 mA utilizing a Q150T Quorum Coater (Quorum Technologies Ltd, East Sussex, UK). The capsule diameter distribution was determined from the micrographs by using an image processing program ImageJ (National Institutes of Health).
Size distributions were obtained from a minimum of 100 measurements.

The morphology of the different types of electrosprayed capsules produced was investigated using scanning electron microscopy (SEM) (Phenom Pro, Phenom-World B.V., Eindhoven, The Netherlands).
Approximately 0.5×0.5 cm of the capsules aluminium sheet was placed on carbon tape and sputter coated with gold, 8 s, 40 mA utilizing a Q150T Quorum Coater (Quorum Technologies Ltd, East Sussex, UK). The capsule diameter distribution was determined from the micrographs by using the open source image processing program ImageJ (National Institutes of Health). One hundred random capsules were measured.
