An apparatus for the preparation of nano-particles which avoids agglomeration of the particles and dramatically reduces the contamination rate, and therefore enables reliable analysis of such particles. The method is based on spraying the volatile solution containing the nano-particles onto the supporting film using a disposable and fairly simple homemade and disposable apparatus which was developed in our laboratory.
A few droplets from the volatile solution containing the nano-particles are dropped into the top needle and sprayed using the pure Ar gas flow from the horizontal needle producing a very fine slurry which lands on the thin film coated TEM grids.
Typical conditions for gas flow:
- Gas pressure – 0.5 atmospheres.
- Flow rate – 2 liters/minute.
