Aim at nanoscale mapping of organic matters, a novel Laser-SNMS instrument was developed by combining an FIB-TOF-SIMS with high lateral resolution and a femtosecond laser with high power. The phase separation structure of polystylene/polyhydroxystylene polymer alloy was analyzed. In case of conventional SIMS mode, the fragmentation signals of the two kinds of polymer were observed. The obtained fragment signal has little quantity, the acquired constituent distribution counts cannot be recognized two polymers. In case of Laser-SNMS, the monomer signal of each polymer was clearly observed. The acquired constituent distribution was able to distinguish each polymer in phase separation structure.
