DIOXINE ANALYZING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide the dioxine analyzing apparatus suitable for simply and rapidly analyzing dioxines by on-line analysis. SOLUTION: Exhaust gas is sampled from a flue by a probe 1 to be introduced into an adsorbing pipe 6 by a pump and dioxines are adsorbed. The dust in the exhaust gas is trapped by a glass filter 7. The adsorbed sample of dioxines is heated by a heater 9 to be desorbed to be re-adsorbed by a cryofocus unit 26 through a duhumidifier. The adsorbed sample of dioxines is heated by a heater 27 to be desorbed and the desorbed sample is introduced into GC/MS 31 (high resolving power gas chromatograph/mass analysis direct connection apparatus) to be analysed. This on-line analysis is controlled by a control part 130 to be performed repeatedly.
