Laser Ablation Electrospray Ionization Mass Spectrometry Imaging (LAESI MSI) of Arabidopsis thaliana leaf

Mass spectrometry imaging (MSI) data set in imzML format, obtained from the 5th leaf of an Arabidopsis thaliana wildtype plant using Laser Ablation Electrospray Ionization. Laser ablation took place with 20 pulses per pixel at an energy of 58.4 µJ/pulse. The ROI measures 9 mm by 5 mm and was sampled with a step size of 200 µm.

本数据集为imzML格式的质谱成像（Mass spectrometry imaging, MSI）数据，通过激光剥蚀电喷雾电离（Laser Ablation Electrospray Ionization）技术，采自野生型拟南芥（Arabidopsis thaliana）的第5片叶片。实验中，激光剥蚀过程每像素采用20次脉冲，单脉冲能量为58.4微焦。该感兴趣区域（Region of Interest, ROI）尺寸为9毫米×5毫米，采样步长为200微米。
