We asked Geraint Morgan, Research Fellow at The Open University, about his experience using SIFT-MS. He discusses how his Syft Tracer has opened up new ways of looking at samples that are difficult to analyze by traditional methods such as formaldehyde and other aldehydes. He also shares his thoughts about its ease of use, mobility, robustness and ability to characterize temporal changes missed by alternative technology. From his point of view, SIFT-MS could be essential for those involved in environmental monitoring.
