MONITORING LOW LEVELS OF FORMALDEHYDE (HCHO) 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.
Standalone system with built-in gas exchange system
Easy-to-use one dial operation
Portability that enables field use
GASERA ONE FORMALDEHYDE photoacoustic gas analyzer is based on combining ultra sensitive cantilever enhanced photoacoustic detection technology with quantum cascade laser source operating at a Mid-IR fundamental spectral absorption line of formaldehyde (HCHO).
This combination provides enough sensitivity (parts per trillion level!) to reliably measure ambient background levels of HCHO. It also gives an exceptionally high level of stability with a re-calibration period ranging from several months up to several years, and thus it offers a low total cost of ownership.
