LC–MS/MS mass traces of pelargonic acid-D17 (test substance, orange trace, m/z 174 → 174) and pelargonic acid-9,9,9-D3 (internal standard, blue trace, m/z 160 → 160) of blank soil extract (a) and extract spiked with the equivalent of 0.3 µg/g D17 (b), 6 µg/g D3 (c) or both substances (d). Note that the signal for D3 was scaled down by a factor of 10 for better comparability
