As high integrated and portable tools, APIX product family is tailored to identify Volatile Organic Compounds in the environment. Analyzing aromatics (BTEX), alcohols, aldehydes, hydrocarbons or other species in the air enable a better control of the presence of potentially harmful species for more secure and comfortable environmental working or living conditions. APIX devices can thus apply to several needs such as industrial hygiene, control of material quality (for buildings), VOCs emissions, air quality diagnostics or safety, water & soil analysis. Silicon-based technologies enable high portability and offer opportunities of volume manufacturing and thus lower costs.
