The combination of the fast, ultra-sensitive Vocus PTR-TOF and this novel autosampler, allows quasi-simultaneous, real-time monitoring of over 100 samples with a single mass spectrometer – providing a unique solution for VOC research in plant science and other fields.
In the context of an ongoing research collaboration between the University of Bern Institute of Plant Sciences and TOFWERK, with support from Abon Life Sciences and Bibus AG, a Vocus PTR-TOF was integrated into a newly developed autosampler (patent pending) to study VOC kinetics of 102 plants in a near-simultaneous fashion. During operation, each volatile source containing a plant is purged by a clean air flow that carries the emitted VOCs directly to the Vocus PTR-TOF for analysis. The autosampler then cycles between individual containers, measuring VOC emissions and plant responses to different stimulants, treatments, or environmental conditions.
See Application Note, High-Throughput Monitoring of Plant VOC Kinetics with a Novel Autosampler and the Vocus PTR-TOF for further examination of the autosampler.
