Optimization of sprayer for matrix application in MALDI mass spectrometry imaging

Datasets archived as .imzML and .ibd raw files (suitable for viewing on multiple platforms - for .imzML, some examples of free software are described at https://en.wikipedia.org/wiki/Mass_spectrometry_imaging .) 1. Imaging file of sectioned spheroids coated using the converted 3D printer without optimization of application parameters (3D_printer_No_Optimization.imzml) 2. Imaging file of sectioned spheroids coated using the converted 3D printer with optimization of application parameters (3D_printer_ Optimized.imzml) 3. Imaging file of sectioned spheroids coated using the commercial sprayer with optimization of application parameters (Commercial_Printer.imzml)本数据集以.imzML和.ibd原始文件格式归档（支持多平台查看——有关.imzML格式的免费查看软件示例，可参阅https://en.wikipedia.org/wiki/Mass_spectrometry_imaging，该页面针对质谱成像（Mass Spectrometry Imaging）提供了详细说明）。 1. 经未优化喷涂参数的改装3D打印机完成包被处理的切片球状体成像文件（3D_printer_No_Optimization.imzml） 2. 经优化喷涂参数的改装3D打印机完成包被处理的切片球状体成像文件（3D_printer_ Optimized.imzml） 3. 经优化喷涂参数的商用喷雾器完成包被处理的切片球状体成像文件（Commercial_Printer.imzml）
