Oxamniquine

Formula: C14H21N3O3 (279.1583)
Adducts: [M+H]+ (Ppm: 10.2) 		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.
