Title: Method and device for analyzing ingredient of gas
Inventor: WATANABE TAKESHI
IPC: G01N27/62
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To make the detection accuracy improvable by removing carbonyl ingredient in an object gas by use of a removing means before ionizing a specified ingredient in the gas. SOLUTION: An object gas is led into a passage therefor 13 to pass through a 2,4-DNPH 12, which removes a carbonyl ingredient therein, so that the 2,4-DNPH selectively absorbs and catches the ingredient from the gas. Accordingly, the carbonyl ingredient with the sensitivity to an ionization detection device 1 is removed and only an HC ingredient is ionized in a hydrogen flame 11. The ionized HC ingredient makes an ion current proportional to the concentration of HC ingredient flow to a collector electrode 2 according to a d.c. voltage applied to an electrode 3. The current is voltage converted by a high resistance at an amplyfing part 5, and from the relation between the voltage value and the HC ingredient concentration, the HC concentration in the object gas is quantitatively analyzed.  In this case, the ingredient to be ionized is only the HC ingredient so that there is no influence of the carbonyl ingredient and an accurate detection can be made without excessive evaluation of the HC ingredient amount.
