Abstract

A high vacuum purification line with lower leakage and lower background level had been established.The contamination of atmospheric argon to the samples was eliminated.The author determined the^{40/³⁶Ar ratios of the samples analyzed previously using new method. Precise sup>40/³⁶Ar ratio is obtained by this system.The sup>40/³⁶Ar ratio observed by the new method is significantly higher than the previously determined ones, and the discrepancy was related to the Ar content of nature gas.Separating Ar from Kr and Xe is basically successful by temperature-modulated cold finger Kr and Xe isotopic compositions then can he measured.}
