[Analysis of blue ballpoint ink components by FT-IR microspectrometry].
Systematical analysis on the 108 kinds of blue ballpoint writing inks with FT-IR microspectrometry is presented in this paper. The results show that the differences of the ink compounds keep some regular. These blue ballpoint writing inks can be classified by the transmittance spectra. The method is rapid, accurate, highly sensitive and nondestructive.
