Report 031


The Shenzhen base is ranked as an important overseas base of the GCOE program, and has achieved certain results as Cooperative Research and Education Center for Environmental Technology. The Shenzhen base is in the stage where concrete research can be conducted. Needless to say, environmental analysis is essential in doing so. Meanwhile, new students in master's programs were assigned to Graduate School at Shenzhen, Tsinghua University at the end of January 2009. Although they take an important role in carrying out research at Shenzhen, they do not have adequate understanding of environmental analysis technology. Therefore, it is necessary to hold a lecture and provide them with knowledge of these technologies. Hence, the aim of this seminar was to lecture basic knowledge of environmental analysis technology and the treatment of measurement data.


Associate Prof. Makoto Yasojima gave a lecture on basic ideas and points to pay attention when conducting environmental analysis, and also how to treat measurement data. For instance, he elucidated the difference between random error and systematic error, and the concepts of accuracy, reproducibility, and repeatability, using examples. Moreover he explained how to set a detection limit, and how to draw the baseline of a chromatogram. After the seminar, the participating students lively exchanged questions and concerns they had on instrumental analysis, ensuring that the seminar provided information they truly wanted to know. They demonstrated the high level of interest; one of them asked a question on the number of duplicate measurement required to guarantee reproducibility. The basic knowledge attained in the seminar will be greatly helpful for the participants in their future research activities.
