Gas sensors for a Healthier, Safer, Greener World

How it Works

A Simple Analogy

Imagine a sponge that can absorb the target gas. Then imagine it sits on a scale that can measure the sponge’s increased weight.

An Innovative Approach

Our sensor uses porous materials called metal-organic frameworks (our sponge) and a quartz resonant mass transducer (our scale).

The Technology

Metal-Organic Frameworks (MOFs) are the world’s most porous materials. MOFs are like molecular “Tinker Toys” where the “sticks” are organic linkers and the “joints” are metal nodes. The gas absorption properties of MOFs can be tuned by varying the linkers and nodes. Over 90,000 MOF structures have been catalogued to date making MOFs the ideal gas sensor material.
