partector TEM

Sampling particles for the electron microscope made easy


The naneos partector TEM sampler is the perfect marriage between simplicity and power: You can use it as a simple survey instrument to quickly identify nanoparticle sources in workplaces. You can also use it to sample particles directly to a standard transmission electron microscope (TEM) grid. The TEM is the most powerful analytical technique when it comes to single particle analysis. The partector TEM allows you to assess workplace safety comprehensively with a single instrument. The partector TEM sampler is the only nanoparticle sampler that can determine the coverage of the sample online, and stop sampling when the optimal coverage is reached. You will never have empty or overloaded samples again.

The 6 key benefits of the partector TEM sampler compared to traditional nanoparticle samplers, are:

 miniature and lightweight
 Easy to use push-button sampling
 Integrated measurement, survey first, sample only when necessary
 TEM grids can be exchanged in the field easily with 6 grid holders
 Automatic determination of the optimal sampling time - because it measures the nanoparticle concentration, it knows when to stop sampling.
 Online display of current sample coverage.


  • LDSA measurement with a time resolution of 1 second (internal instrument time constant 4s; faster on request)

  • Includes a java data analysis tool that runs on all major operating systems


The partector TEM sampler comes in a rugged transport case that contains all accessories necessary:

  • Protective neoprene sleeve - protects the instrument from dirt, water and shocks, and contains a belt loop to attach it to a belt for personal monitoring.
  • Micro-SD-card to USB adapter - to easily read data from the partector's integrated micro-SD-card.
  • USB charger - a standalone USB charger to either charge the partector or run it 24/7 indefinitely
  • 6 TEM grid holders that can be pre-loaded in the lab, and exchanged in the field.
  • Tweezers
  • Box for TEM grids
