Background

Plant VOC Emissions

The interaction of plants with their environment determines their survival in nature and yields in agriculture. Plants can detect VOCs (volatile organic compounds) as environmental cues. Furthermore, they release specific VOCs to attract beneficial organisms or repel parasitoids and as response to biotic and abiotic stresses. The chemical language of plants is mediated by VOCs and is a fascinating subject still largely unexplored. The speed and sensitivity required for real-time detection of such VOCs overcame the performance of existing analytical instruments until the advent of the Vocus CI-TOF. It provides fast, real-time VOC measurements of living plants or plant material at ultra–low concentrations while preserving molecular identity.  Our unique autosampler integration enables quasi-simultaneous, real-time monitoring of over 100 samples with a single mass spectrometer.

(Top) An example of an autosampler cycle measuring a series of 17 plants. Concentrations of select VOCs are plotted at 5 Hz (5 unique mass spectra per second). (Bottom) An example mass spectrum from a single plant averaged for the 15 second measurement cycle shows that hundreds of compounds are detected and monitored in seconds.
