Figure Lengend Snippet: Overview of SPMESH-DART-MS/MS extraction and analysis approach including optimized sample preparation, SPMESH extraction, and DART-MS/MS parameters in this study.
Article Snippet: For SPMESH-DART-HRMS/MS analysis, web-based DART software (version 6.0.5, IonSense Inc., Saugus, MA, USA) was used to manually move the SPMESH sheet on the DART positioning stage unidirectionally through the DART reaction zone at 0.5 mm/sec at a desorption temperature of 350 °C in front of the MS inlet.
