Abstract:
Taking advantage of Confocal Micro-Raman spectroscopy technology，several commercial inkpads and stamppad ink trace variations in four successive years are measured by the IR ( 785 nm) laser，and the data base of time was built up． The results show that inkpads and stamp-pad ink have the 1 235 cm－ 1 characteristic peak on the Raman spectra because of containing the ester． The position of 1 235 cm－ 1 and the relative integrated intensity of the Raman characteristic peak will grow along with time，and in accordance with this result，the trace formation time of the inkpads and stamppad ink can be judged through the contrast of the Raman spectra data of the material with the samples of different age． The confocal micro-Raman technology provides us with a quick，convienent，accurate and non-destructive detection method for the inkpads and stamp-pad ink trace testing．
