Real-time measurement of the 1,2,4-trichlorobenzene (TCB) which is a precursor of dioxin was developed for discharge reduction of the dioxin in exhaust gas from an incinerator. The ion yield was improved using 1-photon ionization by vacuum ultraviolet (Lyman-alpha line of hydrogen (121.6nm)) and ion trap, after solid matters such as a dust were removed. Furthermore, TCB was quantitatively analyzed using the TCB fragment ion generated by ion collision in the ion trap. This method is possible to avoid the influence of much water in the exhaust gas. The calibration curve was described as <i>Y</i> = 0.052<i>X</i> + 4.2 (<i>R</i><sup>2</sup> = 0.9967), and the detection limit was approximately 80 ng/m<sup>3</sup> N as <i>S/N</i> = 2. This calibration curve was sufficiently effective to practical exhaust gas of which TCB concentration is in the range between 0.0 and 6.0 μg/m<sup>3</sup> N. It also presents the real-time monitoring of the 18 s intervals which is due to the signal output.
