The use of the ambient ionization mass spectrometry (MS) have been expanded enormously because of its relatively simple interface and also because of its raw sample analysis capability. Paper spray ionization (PSI) method is the extractive ambient ionization technique that utilizes a triangular shape filer paper as a sampling base as well as an electrospray tip. Active applications of PSI MS include drug monitoring from dried blood spots, food contaminant analysis, and metabolite fingerprinting. In this study, we developed a PSI-based solid sample analysis platform, called paper cone spray ionization (PCSI). Major difference between PSI and PCSI is paper geometry: PCSI uses a triangular pyramid shape or circular cone shape paper base instead of planar triangular shape one. Therefore, a paper base of PCSI can act as a solid sample container and a liquid-solid extraction chamber, as well as an electrospray tip. Analysis of various solid samples and viscous liquid samples such as food powders, animal tissues, and petroleum will be demonstrated in this presentation.
