Nanoparticle Measurement Systems

The name GRIMM Technologies, Inc. enjoys recognition for innovative, high-quality and reliable instruments for the counting and sizing of Nanoparticles. Our customers – universities, research institutes, industrial companies, meteorological services and various authorities (e.g. for occupational health or environmental protection) are using our equipment for research indoors in their laboratories, outdoors in the environment, or even in research aircrafts for their studies and developments.
GRIMM Technologies, Inc. provides mobile, stationary, and also 19“ rack mounted devices for various applications.

NANO particle sizers and monitors

The development of ultrafine aerosol monitoring instruments for real-time Nano air quality studies and monitoring has started in Europe over 15 years ago by GRIMM. These counters and sizers, called SMPS are compact, portable and equipped with a sophisticated optical laser light detection system to monitor the particle size from a few nanometers upwards and their size distribution in many different size ranges up to one micron.

Whether inhalation, exposure, environmental or climatic studies, filter testing, emission measurement or fundamental aerosol research, our equipment can be customized individually in accordance to your requirements.

We are familiar with the smallest particles.

7860The model 7860 Tungsten (“WOx-1”) Generator is used to create defined particle size distributions of very small particles, typically in the range of 1.2 - 20nm.

Nano Product Range

Furthermore, GRIMM Technologies, Inc. has combined their SMPS with optical spectrometers, so that the full airborne aerosol size range can be monitored with one compact system (Mini-WRAS). As a result GRIMM Technologies, Inc. offers a range from small portable battery-operated counters to larger fixed stations for indoor and outdoor use.

Today they are worldwide in use and a range of units is used in the environmental testing and research commonly. High-end electronic permits easy (wireless) data transfer and our powerful software an easy and customer-friendly use of the system.

A range of many different modular Condensation Particle Counter (CPC) models and the Faraday Cup Electrometer (FCE) for the measurement of the number concentration of Nanoparticles, Differential Mobility Analyzers (DMAs) for the size distribution in different size ranges, several Neutralizer types and many Accessories offer the possibility to set up an individual system configuration.

GRIMM Technologies, Inc. takes pride in many scientific articles worldwide showing the use and results of our Nano monitors in the remotest stations from Brazil to the Antarctic for case studies.
