Ethera Technology

Nanoporous material: a unique technology for trapping and measuring formaldehyde

ETHERA’s technology is the result of nearly 10 years of research in a CEA/CNRS laboratory.

It is protected by several patents, and is based on ETHERA’s unique experience in nanoporous materials engineering.

The materials are produced using an established Sol-Gel process. Their porosity results in a subtantial surface area, allowing them to trap large quantities of targeted gases. Thanks to specific colorimetric reagents, measuring pollutants is made possible, based on the color variation of these initially transparent materials. The reading can be performed visually or with an optical reader for more accurate results.

This technology enables us to design highly sensitive and selective sensors. Incorporated in our measuring kits, it detects and quantifies with great precision the concentration of chemical pollutants, particularly volatile organic compounds (formaldehyde, BTEX, aldehydes, etc.)

This technology is embedded in our monitoring, diagnostic IAQ stations and treatment solutions.

Colorimetric sol-gel material is embedded in specific sensors for formaldehyde for IAQ topics and trichloramine for indoor swimming pool topics. With a high level of sensitivity, these solutions can be used for the most challenging scenarios.
