It was strongly dependent on the overall mass fraction of solvent. 77 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia ANA-P4 DEVELOPMENT OF MULTIPLY-HYPHENATED ANALYSIS SYSTEM FOR PROTEOMIC AND EPIGENETIC RESEARCH Tomonari Umemura and Shin Shu Division of Nano-materials Science, EcoTopia Science Institute, Nagoya University Furo-cho, Chikusa-ku, Nagoya 464-8603, Japan E-mail: umemura@apchem.nagoya-u.ac.jp More accurate and more informative analysis is really required in the current competitive life sciences and industries, and so far substantial efforts ha ve been dedicated to the development of multidimensional HPLC system and MS-based hyphenated system. We are now developing a variety of user friendly microbore monolithic columns using a monolithic column technology, and applying them to achieve high-throughput bioanalysis. In the first part of this paper, we present the current state of our research on the development of organic polymer monoliths with different chemical functions and their applications to the analysis of proteins, peptides, or oligonucleo tides. In the second part, we will present the challenges to the development of a) two- or more-dimensional HPLC system and b) multiplyhyphenated analysis system with ICP-MS and ESI-MS. ANA-P5 ELECTROGENERATIVE PROCESS FOR THE RECOVERY OF LEAD USING A BATCH CELL Nurul Hanis Mohd Ramalah, Nur Fatin Zakaria, Fatemeh Salehi Karoonian, Mohammad Etesami and Norita Mohamed School of Chemical Sciences, Universiti Sains Malaysia, 11800 Pulau Pinang, Malaysia E-mail: mnorita@usm.my A batch electrochemical reactor operating in an electrogenerative mode was used in the recovery of lead. This operation is attractive in reducing operating costs due to the spontaneous chemical reaction that take place in the reactor. A batch cell using three-dimensional cathodes namely porous graphite or reticulated vitreous carbon were coupled with a zinc anode. The performance of the...
