We showed that our new single wall carbon nanotubes substrate (SWCNTs substrate) with a nano-sized network structure on its all surface areas was very efficient for high performance ionization of analyte molecules. A preparation procedure of our SWCNTs substrate requires mainly two processes that are a well dispersion of SWCNTs in preparing solution and a very thin laying-up on a surface of base plate. Moreover, we found that base plates for laying-up of SWCNTs determines its analytical performance and a SUS plate is a good base plate. We expect that further investigation of base plates in our SALDI-MS technique using the SWCNTs leads to more efficient ionization. [DOI: 10.1380/ejssnt.2009.546]
