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 makes measuring the number concentration of nanoparticles easier than ever before. Because the testo DiSCmini contains the research know-how from Matter Aerosol AG, which has been part of Testo since 2010.

The challenge

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 is be convenient 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

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 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

Measure and classify nanoparticles at the press of a button

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.

Environmental and work sciences examine the influence of nanoparticles on humans and the environment.

This requires a number of different measurement methods.

Read now in this application example how the testo DiSCmini combines these measurement methods in one instrument to facilitate the systematic investigation of particle emissions.

Which risks do nanoparticles present for humans and the environment?

Environmental authorities and research institutes have to conduct extensive examinations for recording and evaluating the particles.

The application example shows how the testo DiSCmini is used in environmental protection and in health and safety.
