アセチレン量の損失が多くなり、経済上好ましくない。By using this acetylene gas for atomic absorption and atomic emission spectroscopy, there is no signal suppression phenomenon, and there is no change in signal intensity over time, allowing highly sensitive and highly accurate analysis of all metal elements. It is particularly effective for calcium, strontium, lithium, potassium, sodium, and molybdenum. If the concentration of impurities in acetylene gas is higher than the above-mentioned concentration, phosphorus compounds will suppress the atomic signal, reducing analytical sensitivity, and sulfides and hydrocarbons with 3 or more carbon atoms will increase signal noise. Analysis accuracy decreases. Regarding acetylene gas purity, if it is lower than the purity stated above, atomic signal suppression phenomenon is observed, and the change over time associated with the release of acetylene gas from dissolved acetylene is rapid, so data reproducibility is a problem. Become. The highly purified dissolved acetylene used in the atomic absorption and atomic emission spectroscopy of the present invention is made by oxidizing and fixing hydrogen phosphide and hydrogen sulfide in crude acetylene gas using a solid detergent, A-type zeolite, and activated carbon. It adsorbs and removes moisture, sulfides other than hydrogen sulfide, and hydrocarbons having 3 or more carbon atoms. After filling this treated gas into a container containing a DMF-infiltrated porous material, 5-20% of the filling gas is
Oxygen, nitrogen and methane can be reduced by releasing preferably 10-15% amounts. If the released m is less than the above ratio, sufficient purity cannot be obtained, and if it is larger than the above ratio, dissolved acetylene with low contents of oxygen, nitrogen and methane in the acetylene gas can be obtained, but the amount of charged acetylene is lost. This is not economically desirable.

置後行うのが、効率的に酸素、窒素及びメタンを低減さ
せることができるので、経済上の観点から好ましい。Acetylene gas release is not particularly specified, but
From an economical point of view, it is preferable to carry out the reaction after being allowed to stand for 24 hours or more, preferably 48 hours or more after filling the container, since oxygen, nitrogen and methane can be efficiently reduced.

から分析データの再現性が向上する。Dissolved acetylene subjected to the above treatment has a significantly smaller change in impurities over time due to the release of acetylene gas than conventional dissolved acetylene, and does not suppress atomic signals even when used in atomic absorption and atomic emission spectroscopy. , the reproducibility of analytical data is improved because there is no change over time.
