DETAILED DESCRIPTION - The apparatus comprises solvent preparation modules (15), particle synthesis modules having three independently heatable chambers, an analytical device, first shell structure modules for the synthesis of core shell particles, a second shell structure module connected to the first shell structure module for the manufacture of core-shell-shell particles, and pumps (50a, 50b, 50c) connected between degasser units (40a, 40b, 40c) and solvent organizer units (45a, 45b, 45c) to control the flow of the particle precursor solutions through the apparatus. The solvent preparation modules are connected in series with the particle synthesis module and connected to a precursor source, and comprise degasser units and solvent organizer units. The heatable chambers comprise preheating chambers for individually and simultaneously preheating separate solutions of particle precursors, a nucleation chamber for mixing the solutions of particle precursors and nucleating the precursors, and a growth chamber for the growth of particles. The degasser units and/or the solvent organizer units are connected to the precursor sources (30a 30b, 30c). The analytical device is connected to the growth chamber, and comprises an absorption emission spectrometer, a x-ray crystallography device, a light scattering measurement device and a nuclear magnetic resonance (NMR) spectrometer. The shell structure modules are connected to the particle synthesis module. The preheating chambers are connected to the degasser units and the solvent organizer units, and the nucleation chamber is connected to the growth chamber and the analytical device, which is connected to a particle collector and an analysis outlet. The pumps are made of an inert material. The apparatus is inert with respect to the particle reactants used for the manufacture of the nanoparticles. The analysis outlet is useful for in situ collection and for analysis of manufactured nanoparticles, and is connected to the analytic device. The particle collector is connected to the analytical device and connected between the particle synthesis module and the shell structure module. An INDEPENDENT CLAIM is included for a method for the manufacture of nanoparticles.
