Abstract：A new method for analysis of cobalt phthalocyamine sulfonates(CoSPC) by thin layer chromatography/flame ionization detector (TCL/FID) was investigated. Different compounds in CoSPC can be separated by TLC, and structure can be further identified by matrix-assisted laser desorption/ionization-time-of-flight-muss spectrometry (MALDI-TOF-MS). Experimental results indicated that commercial CoSPC has three compounds, cobalt phthalocyanine (CoPC) mono-sulfonates with two isomers, CoPC di-sulfonates with five isomers and CoPC- tri-suflonates, TCL/FID could be used to determine the amount of different compounds. This method is featured by its ease operation, quick response, good separation and satisfactory results.

Keywords：Cobalt phthalocyanine sulfonates, thin layer chromatography/flame ionization detector, matrix-assisted laser desorption/ionization-time-of-flight-mass soectrometry
