ProCeas® Formaldehyde
As per the international OH&S regulations on formaldehyde, private and public sector evaluated several technologies to implement continuous real-time monitoring of formaldehyde in ambient air in their plant facilities.
The ProCeas® has been selected as the most suitable technology according to their monitoring needs in terms of response time, accuracy and flexibility.
Customers use the ProCeas® to measure various levels of formaldehyde in the air at different locations: laboratories, offices & workshops.
Technologies
OFCEAS Technology
For indoor air quality monitoring, the ProCeas® spectrometer is equipped with a laser at a single wavelength used to determine the concentration of a specific compound with an extremely low detection limit and short response time.
The OFCEAS extended optical path and continuous signal feedback provide a high- definition spectral response using a traditional absorption measurement.
The OFCEAS system uses a high-finesse optical cavity to provide path lengths of dozens of kilometers.
The OFCEAS technology can also take advantage of light sources to provide multi-component analysis, while offering improved sensitivity (ppb).
