New Method for Identifying Carbon Compounds Derived from ...

Sep 12, 2017· The CRDS instrument that Fleisher and Long have developed can sit on a laboratory benchtop and is relatively inexpensive to operate. CRDS instruments analyze gases by detecting the wavelengths of light they absorb. For instance, CO 2 that contains carbon-14—so-called heavy CO 2 —absorbs a slightly different wavelength than regular CO 2.

Putting carbon dioxide to good use | MIT News ...

Sep 22, 2010· The MIT team’s biological system captures carbon dioxide at a higher rate, says Barbero. Another advantage of the biological system is that it requires no heating or cooling, and no toxic chemicals. Next, the team plans to try scaling up the process to handle the huge volumes of carbon dioxide produced at fossil-fuel-burning power plants.
