摘要：PROBLEM TO BE SOLVED: To enable miniaturization of an apparatus, use of a thinner material, and easy measurement work in a method for measuring a content of a hydrocarbon component contained in a soil and realize in a short time complete vaporization of a wide range of the hydrocarbon component contained in the soil, from a light distillate to a medium/heavy distillate. SOLUTION: A vaporizer includes a heating furnace 2, a sample holder 3, and a sample holder mounting section 4 to be installed inside the heating furnace 2. The sample holder mounting section 4 has an opening 5 at the upper end thereof for mounting the sample holder 3, an introduction passage 9 at a lower end thereof for introducing a mixed gas of oxygen and nitrogen, and a discharge passage 10 on a side thereof for discharging a vaporized component. The sample holder 3 has a filling port 7 at the upper end thereof for filling with a soil sample, and a sample chamber 6 therein. A mixed gas introduction port 9a connected to the mixed gas introduction passage 9 is provided at the bottom of the sample chamber 6, and a discharge port 10a connected to the discharge passage 10 for the vaporized component is provided on the side of the sample holder 3, which corresponds to the upper part of the sample chamber 6. The filling port 7 is provided with an airtight plug 8. COPYRIGHT: (C)2010,JPO&INPIT
