Mass spectrometry (MS) has been used extensively because of the development of ionization methods followed by their improvement and the solution of analytical problems in inorganic and organic chemistry, biochemistry and medicine. MS has become a powerful and standard method for the identification, structural determination and elucidation of wide variety of compounds, when it is employed in complementary with other physical methods such as nuclear magnetic resonance (NMR), X-ray diffraction and infrared spectroscopy (IR). However, there are still many problems to be solved in MS. In this paper, I proposed the improved methods which may be helpful for solving the problems.
