IONICON is a proud sponsor of Gordon Research Conferences

We support young researchers at two GRCs in 2012

The Gordon Research Conferences provide an international forum for the presentation and discussion of frontier research in the biological, chemical, and physical sciences, and their related technologies.

Two GRCs closely related to our own scientific research and PTR-MS are now supported by IONICON in order to give young researchers the opportunity to present their work to the scientific community.

These days the GRC for Plant Volatiles takes place in Ventura, CA, January 29 – February 3, 2012 and has as topics: Ecology, Biosynthesis, Regulation and Animal Perception of Floral and Vegetative Volatiles, Plus their Roles in Human Flavor and Agriculture.


Ultra-sensitive and fast detection of BVOC emissions with IONICON PTR-TOF

Detection of Plant Volatiles after Leaf Wounding and Darkening by Proton Transfer Reaction ‘‘Time-of-Flight’’ Mass Spectrometry (PTR-TOF)

A new study published yesterday, where IONICON PTR-TOFMS was used to detect biogenic volatile organic compounds (BVOCs) induced by leaf wounding and darkening, shows the huge potential of PTR-MS for monitoring and quantification of  fast processes in our environment. Leaf wounding reactions where BVOCs are emitted occur very fast and therefore a method is necessary that can capture the BVOC profiles in seconds. A very high time resolution and sensitivity in combination with the high mass resolving power of a time of flight makes the PTR-TOFMS technology an ideal tool for such applications. PTR-MS can detect most of the common VOCs in real-time, in very low concentrations and without complicated sample preparation as our online mass spectrometers directly inject the sample gas and provide results without delay.

The study is an outcome of the Marie Curie Industry-Academia Partnership and Pathways (IAPP) project 218065 ‘‘PTR-TOF’’ funded by theEuropean Commission within the Seventh Framework Programme (FP7 – People), where IONICON is one of the partners.
