Why count nanoparticles?

Nanoparticles surround us without us consciously noticing them. Because they are so small, they present certain dangers. In traffic and in polluted workplaces, certain nanoparticles can be harmful to health. Special hazards are present in:

  • Public areas with heavy traffic (diesel soot)
  • Soldering and welding workstations (formaldehyde, metal oxides)
  • Foundries (phenols)
  • Office workstations (toner dust from printers and photocopiers)

The portable testo DiSCmini particle counter measures the number concentration of nanoparticles easier than ever before.

The challenge

The challenge of nanoparticles

Due to their variety of size, spread and composition, nanoparticles are a challenge for measuring technology. Extensive examinations are required for a reliable assessment of the particle emission. Conventional particle counters are sensitive to vibrations, function only in one certain position and require additional operating media. Wouldn’t it be more convenient and advantageous to have a portable instrument that can accomplish these tasks?

  • Precise capturing of personal exposure in real time and close to the person
  • Reliable workplace risk assessment
  • Fast verification of filter efficiency
  • Easy monitoring of air contamination with one mobile instrument or several stationary instruments

The solution: testo DiSCmini

testo DiSCmini

The testo DiSCmini masters the challenge of particle measurement at the press of a button. Particle number concentration, modal diameter and lung deposited surface area (LDSA) are measured simultaneously and at (1) one-second intervals. Thanks to these advantages, the measurement is simple:

  • The testo DiSCmini is easy to carry and is immediately ready for use without settings and calibration.
  • The instrument is not affected by vibrations and can be operated in any position.
  • No inflammable or radioactive operating media are required.

testo DiSCmini white paper

Soldering workstations require efficient measures for protecting workers. Our white paper uses an example to describe health and safety checks using the testo DiSCmini and identifies the advantages offered by our nanoparticle measuring instrument compared to previous measuring methods:

  • Comprehensive health and safety through precise recording of nanoparticle exposure of the worker
  • Fast capturing of the background levels at the workstation and identification of particle sources in the surroundings
  • Easy optimization of the workstation for the lowest possible nanoparticle exposure

Measure and classify nanoparticles at the press of a button

testo DiSCmini brochure
  • The testo DiSCmini can record nanoparticles where they become medically relevant – in the direct surroundings of humans
  • The testo DiSCmini can also measure and classify particles which are not detected by gravimetric methods
  • The testo DiSCmini provides essential decision making tools on the path to a higher quality of ambient air in the workplace, in traffic and in public spaces
Due to their small size, nanoparticles can penetrate deep into the lungs and enter all areas of the body through the bloodstream. The interview with Professor Dr Peter Gehr from the Institute for Anatomy at the University of Bern identifies the hazards of nanoparticles and points out the opportunities of comprehensive nanoparticle measurement with the testo DiSCmini.

testo DiSCmini in use for research

The significance of a measuring instrument is not only evident in the questions it answers but also in the people who use it. In our Book of Abstracts, we have collated over 110 studies from scientists all over the world in which testo DiSCmini plays an essential role. This includes the following topics:

  • Personal exposition to nanoparticles and the health consequences
  • Nanoparticles and their significance for health and safety
  • Monitoring the quality of ambient air and evaluation of air pollution

The cleanest rooms in the world are not in hospitals but in the production facilities of the semi-conductor industry.

As manufacturing structures become ever smaller, the processes are becoming increasingly sensitive to interferences.
