partector 2 Pro

Handheld ultrafine particle size distribution measurement

Benefits

The naneos Partector 2 Pro is a further development of the well-established Partector 2. The Pro version of the Partector 2 can operate in a scanning mode and measure an 8-channel size distribution from 10-300nm.

The 10 key benefits of the Partector 2 Pro version are:

 ultrafine particle size distribution measurement from 10-300nm
 multiple other particle metrics
 miniature and lightweight
 hassle-free & simple measurements
 fast startup time
 orientation-independent operation
 wide particle concentration range
 silent pump
 great battery life
 size distribution analysis with our freely available software

Limitations of the scanning mode
The size distribution measurement with the Partector 2 Pro comes with some drawbacks that you should be aware of:

  • The time resolution in the scanning mode is lower than in the standard mode (typically 6 seconds instead of 1 second).
  • If the aerosol changes during a scan, the Partector 2 Pro measures different aerosols at different times, and the resulting size distribution will be inaccurate - like in other scanning devices.
  • The size distribution measurement relies on the measurement of small signal differences. The measurements in the scanning mode are generally noisier than in the standard mode.

For rapidly changing aerosols or low concentration measurements, the Partector 2 Pro can be operated in the standard (non-scanning) mode. If you have questions which version is right for your application, please contact us.

Long-term ambient measurements
There is a growing interest in long-term (≥ 1 year) size distribution measurements in monitoring stations with the Partector 2 Pro instead of complex and expensive scanning mobility particle sizers (SMPS / MPSS). Although first comparative studies with ~3 months of continuous operation are promising, we would like to caution against too great expectations. The P2 was developed as a handheld device and optimized for size and weight, not for long service intervals. We are in the process of studying the long-term stability of the size distribution calibration, but this necessarily will take a long time.
