<p>PURPOSE:To improve the purity of gas, by making gas contact with Na to remove a small amount of impurities such as oxygen contained in the gas. CONSTITUTION:A gas contained in a bomb 1 is introduced to the lower side of a Na-vessel 6 filled with Na, and is made pass through the Na; a small amount of impurities such as oxygen contained in the gas is removed by utilizing the reaction of Na OH formation from Na and water. Next, the highly purified gas is enclosed within a tank 5. Thus the reliability of analyzed values of samples e.g. samples requiring the accuracy of analysis, is improved by using the high purity gas in the tank 5.</p> |
