Background
Plant VOC Emissions
The interaction of plants with their environment determines their survival in nature and yields in agriculture. Plants can detect Volatile Organic Compounds (VOCs) as environmental cues. They also release specific VOCs to attract beneficial organisms or repel parasitoids and as a response to biotic and abiotic stresses. As climate change expands the range of pests and alters temperatures and rainfall patterns worldwide, understanding plants’ chemical responses is more vital than ever.
Despite its intriguing nature, this research subject remained largely unexplored due to the analytical challenges posed by the speed and sensitivity required for real-time detection of such VOCs. The research landscape transformed with the introduction 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. Integration of the Vocus CI-TOF with the unique TOFWERK plant autosampler enables real-time monitoring of over 100 samples with a single mass spectrometer in a matter of minutes. Thus allowing us to finally understand how plants respond to their environment and to our changing world.
Solutions
High-Throughput Analysis of Plant VOC Emissions Using the Vocus CI-TOF with Novel Autosampler
- High mass resolving power enabling accurate identification and quantification of plant VOC emissions.
- Market-leading sensitivity with sub-ppt limits of detection (LODs).
- Fast-time response allows real-time characterization of plant VOC emissions.
- Custom-designed plant autosampler enables near-simultaneous, real-time monitoring of over 100 samples in a few minutes.
(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.
