How ripe is your produce? This sensor can tell you -

2020-05-11· Researchers at MIT have developed a sensor to monitor the plant hormone ethylene to determine when fruits and vegetables are about to spoil. “Ethylene is a big part of how nature regulates itself,” says Timothy Swager, John D. MacArthur professor of chemistry at MIT and lead author of the study, which is published in ACS Central Science.. “It causes fruit to ripen, can cause trees to ...

C2H4 sensors | Ethylene Detection | smartGAS

Wherever ethylene is to be found, the concentration of the gas plays an important role. The C 2 H 4 gas sensors of the FLOW EVO series from smartGAS safely and reliably detect the presence of ethylene in a measuring range from 0 to 2000 ppm. The sensors operate based on the principle of the non-dispersive infrared absorption of gases (NDIR ...

New sensor could help prevent food waste | MIT News ...

2020-03-18· In 2012, Swager’s lab developed an ethylene sensor containing arrays of tens of thousands of carbon nanotubes. These carbon cylinders allow electrons to flow along them, but the researchers added copper atoms that slow down the electron flow. When ethylene is present, it binds to the copper atoms and slows down electrons even more. Measuring this slowdown can reveal how much ethylene …

Ethylene Gas Detector | Solutions | Buy

Ethylene (C2H4) is a colourless gas which is highly flammable with a Lower Explosive Limit of % in air. Studies have indicated a low toxicity of ethylene and no risk to human health has been identified. It is naturally occurring, but it can also occur as a result of combustion and is manufactured by industrial processes from Methane and petroleum.
