Introduction
Analytical chemistry laboratory consists of a material characterization research group and an environmental analysis research group. The material characterization research group studies the technologies to characterize inorganic materials including advanced ceramics from the viewpoint of spectroscopic analysis. The results have been used for the establishment of the standards for evaluation methods such as JIS, and for the creation of higher performance materials and new-functional materials. The development of advanced ceramics standard reference materials is also the objective of the group. The environmental analysis research group conducts studies from the viewpoints of ion chromatographic analysis. The group has developed an automatic acid rain analyzer consisting of an ion chromatographic analyzer and a meteorological analyzer. The group collaborates with several domestic and foreign laboratories. The objective of the group is to construct an acid rain monitoring network in east Asia.

1. Chemical characterization of inorganic materials
The aim of this study is to establish analytical methods for metallic and non-metallic elements in a wide variety of inorganic materials by using ICP-AES, ICP-MS, combustion analysis, etc. Our interests are focused on trace and ultra-trace analyses of ceramic materials and also including microanalysis and state analysis by using SIMS and FT-IR.
Secondary ion mass spectrometer (SIMS)
The scope of this study covers development of processing technologies for preparing well-controlled starting particles in shape and structure and evaluation of their chemical properties. This will produce useful industrial materials with new excellent properties.
We have evaluated the homogeneity in a several-component system, alumina and silica, by using XRF and examined non-metallic impurities determination in SiC powders.

3. Development of acid rain monitoring system in east-Asia
Evaluation of acid rain effects in east Asia has been accomplished with an automatic acid rain monitoring system consisting of a simultaneous ion-exclusion/cation-exchange chromatographic acid rain analyzer (Acid rain monitor), coupled with a meteorological analyzer with GMS-5 (Himawari) and AMeDAS (Automated Meteorological Data Acquisition System). This system is successfully applied to the monitoring of acid rain in east Asia. This joint study is carried out with Iowa State University, Texas Tech University, University of Tasmania, Chungpook National University, and Kyungpook National University, based on bilateral cooperative agreement for environmental protection as well as on science and technology.

4. Development of advanced inorganic packing materials for chromatography
Chromatography is well known as a fundamental technique for the separation and preparation in modern science and technology. The heart of chromatography is the separation column packed with organic or inorganic particles (packing materials). The modification of inorganic particles (i.e. silica gel) with various kinds of metals will be done in the project for the development of newly advanced packing materials.
