Real-time monitoring of low formaldehyde concentration in outdoor and indoor ambient air!

Thanks to the clever combination of an ultra-sensitive cantilever enhanced photoacoustic detection technology and a Quantum Cascade Laser source, the Gasera One Formaldehyde is able to provide enough sensitivity (sub-ppb level!) to reliably measure ambient background levels of formaldehyde in real time.



It also gives an exceptionally high level of stability with a re-calibration longer than one year, and thus it offers a low total cost of ownership. A major advantage of the photoacoustic effect is that sensitivity is not dependent on the absorption path length. This allows high sensitivity with a short absorption path length, and a highly linear response over a wide dynamic measurement range with very low sample volumes (typically only a few milliliters). Have a quick look at the short video presenting the device.



The Gasera One Formaldehyde was field tested in static and dynamic conditions at a holyday and training center in Southern Finland. The center consists in eight separate wooden houses, built from 1950s to 1990s. The indoor air formaldehyde concentration was recorded in 50 rooms during the testing and varied from 4 to 200 μg/m3. The highest formaldehyde concentrations were measured in rooms where 1970s particle board was abundantly used in combination with poor ventilation. The average indoor air formaldehyde concentration clearly exceeded the annual average value of 50 μg/m3 (decreed by the Finnish regulation) in two buildings.



The measurement results of the Gasera One Formaldehyde were compared to the measurement results of the more traditional DNPH method based on cartridge sampling and liquid chromatographic laboratory analysis (reference method). The results agree well considering that the reference method has an uncertainty of 15 % and a minimum detectable formaldehyde level of 5 μg/m3.

This study showed clear differences in measured formaldehyde levels based on the building type. It also highlighted analyzer sensitivity, linearity and fast response time to ambient and indoor concentrations changes. Moreover, field measurements of the GASERA ONE FORMALDEHYDE in comparison against reference method showed high consistency. More results from this study are available here in the related application note.

New reference lab setup News: New reference lab setup

Envicontrol has installed the new reference lab of IBGE/BIM in their new building located in the “Jardin Massart” area in Brussels. The system delivered is made for calibration and validation of the devices used for the ambiant air monitoring networks in Belgium.

The installation contains MCZ’s central supervision system, MCZ’s calibrators with zero air system and dilution (to work with high concentration cylinders) and MCZ’s Lab equipment furniture.

The Envicontrol team has realised the full installation with the racks, laboratory tables, piping, wiring, communication… and commissioning.

Are you interested in such a system? Or would more information? Please drop a line to sales@envicontrol.com.

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.
