5-KETE Formula: C20H30O3 (318.2195) Adducts: [M-H2O+NH4]+ (Ppm: 6.5)	Marker Pen (NA)	3ul_0.8Mpa_RAW_20241016-PAPER PNMK Resolution: 30μm, 315x42 Description By writing the four English letters “PNMK” on white paper with a marker pen, and then scanning with a DESI ion source to obtain the scanning result. The signal of the chemical substances on the marker pen used appears on the channel with an m/z value of `322.1918`, `323.1953`, `546.4010`, and etc, from the single cell deconvolution sampling layer `class_4`. This test data was tested by chuxiaoping from PANOMIX’s R&D laboratory.
