An ion chromatography system was installed at chemistry laboratory of Yuge maritime college in August 2004. Using the system, we established the measuring methods and verified their performances. Measured ion species were anion (F-,CH3SO3-,Cl-,NO2-,NO3-,PO43-,SO42-) and cation(Na+,NH4+,K+,Mg2+,Ca2+), which are the major elements contained in the natural precipitation of the world. The minimum volume was 1.5ml each sample. As a result, we established the measuring methods of concentrations from several 100 μg/l to mg/l in each ions, and the concentrations correspond with the ice in inland Antarctica to rain throughout Japan, respectively.
