The localization of procymidone fungicide residue in cucumbers was investigated by mass spectrometry imaging (MSI). Cucumbers were grown, harvested, and then divided into two groups that were either sprayed or not sprayed with procymidone. The content of procymidone in the cucumbers was quantitatively determined by chromatographic techniques. Subsequently, the spatial distribution of procymidone was imaged by MSI. Procymidone reached the central part of the cucumbers following spraying compared with the control.
采用质谱成像技术（MSI）研究了杀菌剂菌核净在黄瓜中的定位。黄瓜种植、收获后，分为喷洒和不喷洒菌核净两组。采用色谱技术定量测定黄瓜中菌核净的含量。然后，通过 MSI 对菌核净的空间分布进行成像。与对照组相比，喷洒后菌核净到达了黄瓜的中心部位。
