Making the invisible measurable

Viruses can be transmitted via aerosols. The risk of transmission should be reduced as far as possible.

Opinions vary, however, on how to achieve this. Some believe that it is sufficient to increase the air exchange rate of rooms. Others call for installation of highly efficient air purifiers in all classrooms, conference rooms, or doctor’s waiting rooms not connected to an appropriately designed central air filtration system, as a general rule.





In the face of Covid-19 and future challenges decision makers in the public and private sectors need objective guidance for specifying requirements to be met by individual air hygiene concepts. More reliable data is required.

Sole measurement of the CO2 level is insufficient for optimal design of ventilation concepts and determination of required air filtration capacity, which complicates the task further. Virus carrying aerosol particles are so small that most measuring devices can’t detect them.


Indoor spaces vary considerably regarding dimensions, furnishing, technical facilities and uses, as well as occupancy needs. This calls for individual on-site assessment by experts in this field.

With appropriate measurement technology, potentially infectious aerosols can be reliably determined – the basis for developing reduction concepts.

With the AQ Guard Indoor and its new Indoor Air Hygiene Professional software package Palas offers a tool for experts in the field: A specific indoor situation (e.g., a class lecture or a meeting) can be rated by providing values for infection risk and Air Quality, based on combined data gained from simultaneous measurement of CO2 and particle count.

Monitoring low levels of formaldehyde in ambient air News: Monitoring low levels of formaldehyde in ambient air

Formaldehyde, chemical formula HCHO or CH2O, is a colorless gas with a pungent odor. Levels above 0.1 ppm can cause allergy and acute health problems, e.g. sore throat, skin irritation, nausea, scratchy eyes and cough. Formaldehyde (HCHO) is also classified as highly carcinogenic compound. Exposure to moderate amounts of HCHO has been linked to cancer, such as leukemia.

New carbon dioxide isotope analyzers News: New carbon dioxide isotope analyzers

Stable isotopes act as tracers for studying flows and fluxes of material through ecosystems and the atmosphere. In practice, scientists measure the stable carbon isotope content of air, plants and soil to quantify many phenomena including the recycling of carbon dioxide within forests, water use efficiency, partitioning ecosystem carbon exchange into its components, gross primary productivity and ecosystem respiration, and to identify and quantify the distribution and contributions of plant species to global productivity. In addition, stable isotopes of carbon may be used to determine the effectiveness of carbon sequestration strategies. For these studies, investigators require fast, accurate measurements over a wide range of carbon dioxide concentrations.

ABB LGR-ICOS Carbon Dioxide Isotope analyzers exceed all of these requirements.

Droplet's CCN-100/200 measures the count and size of individual aerosol particles that can form into cloud droplets. Its fast response time allows use in either airborne or ground-based stations.

Photoacoustic detector for solid, semi-solid and liquid samples News: Photoacoustic detector for solid, semi-solid and liquid samples

The INRAe of Narbonne has bought an ultra-high performance photoacoustic detector for solid, semi-solid and liquid samples (a PA301 module produced by Gasera). The PA301 is used as an accessory for any FTIR device. Last week, the Envicontrol team provided on site setup and a full training has been given.

Flux measurements News: Flux measurements

Los Gatos Research (LGR) now offers more analyzer choices to measure surface-atmosphere fluxes. Traditionally, there are four main flux measurement techniques: Eddy Covariance, Relaxed Eddy Accumulation, Gradient and Chamber-based. Though carbon dioxide and water vapor are the most common greenhouse gases measured, in many ecosystems a number of different gases must be measured. LGR's technology has improved rapidly over the years and new analyzers are now available allowing scientists to expand their research by measuring other greenhouse gases such as methane, nitrous oxide, carbon monoxide, ammonia, and carbonyl sulfide.
