| Research Abstract |
Multiphoton ionization/time-of-flight mass spectrometry (MPI/TOFMS) provides a high degree of optical selectivity and soft ionization properties. Recently, I developed a new sample introduction system based on online concentration by analyte adsorption and subsequent laser desorption (online COLD). In the present study, a sensitive and selective analytical method was developed for direct measurements of aromatic compounds in an aqueous solution. Moreover, a novel analytical approach to elucidate the reaction process by using the online COLD technique was reported. The occurrence of molecular reactions by introducing an intense laser for desorption in online COLD was confirmed.
