The soil microbes alter the smell of the garden lupine. The smell is studied by collecting the volatile organic compounds emitted by the leaves. The plants are enclosed in oven bags, and filtered air flows through the bags collecting the smell to the trapping tubes. The smell consists of several individual compounds which are separated with gas chromatography.
