Molecule ions with a lower molecular weight (M<350) is able to be detected by the technique of an atmospheric pressure ionization mass spectrometry(API-MS), but there are almost no techniques to examine the fraction of ionized VOCs with a high molecular weight. Therefore, the purpose of this study was to determination of possibility for fraction of ionized VOCs using the adsorption surface under various electric field. To achieve this purpose, expriments are conducted under the condition of ionizer's(+,-,off) and electric field's(+,-,off) as the basis. This results will be reported. |
