°Silver Particle Generator generates solid silver aerosols used for calibrating particle counters, emission studies, and air quality research an easy and effective way.
APPLICATIONS
- CPC calibration (ISO 27891, 15900, CENS)
- Euro VI and VII PMP
- PCRF & VPR validation
- PN-PEMS calibrations
- Mask filtration efficiency studies
- Line-loss measurements
- Filter loading
Practical Example
To generate spherical silver particles of sizes 2.5 – 100 nm, you can use our instruments in the following setup:
Combination of SPG and S8000 generates spherical, thermally stable silver particles with up to 100 nm electrical mobility diameter (confirmed by TEM)
Resulting aerosols are similar to a classical double tube furnace setup
Sintering behavior described by Ku et al., 2006, confirmed:
- First sintering occurs around 100 °C
- Above 400 °C sintering temperature no change in electrical mobility diameter observable
No effect on CPC calibration (d50 = 10 nm) for sintering temperatures 400 – 700 °C
