Example for Calibration
To generate sintered silver particles of sizes 2 – 100 nm we recommend to use the following setup
The SPG produces silver particles that agglomerate in the Residence Chamber and the P1000 PCRF Accessory Kit. The large agglomerates are sintered in the S8000 Particle Sintering Device and size selected in the DMA for the calibration application. The SPG’s ability to control the heater temperature in precise 1°C steps not only allows for stable production of narrow size distributions of spherical silver particles but also enables the ability to shift these distributions by tuning the temperature. The resulting silver particles cover diameters up to 100 nm at concentrations between 10³ and 10⁶cm⁻³.
This setup presents an easy, flexible, and stable method for generating solid, unreactive, insoluble, thermally stable, and spherical silver particles with diameters up to 100 nm. These particles can be used for calibration of CPC or PCRF or for any other UFP application requiring a highly defined, stable aerosol source.
