Summary
-
1.
A method was proposed for the frontal concentration of impurities by reversible chemical absorption using a basic material.
-
2.
It was shown that it is possible to chromatographically determine hydrocarbon impurities at a concentration of 1·10−5−1 · 10−6 volume% in carbon dioxide, by employing the procedure of their prior frontal-chemical concentration.
