Cryogenic chromatography has been applied for the quantitative analysis of highly elusive gases or materials, which are difficult to separate on various analytical columns. In many cases, their separability can be increased by cooling the analytical columns with liquid nitrogen or liquid carbon dioxide. However, coolant consumption and maintenance are significant issues in industrial settings as well as in laboratory experiments, in terms of economy and time. To improve the merit of chromatography as an on‐line analysis tool, we report herein a gas chromatography method that does not use consumable coolants such as liquid nitrogen or liquid carbon dioxide, and explored its application for providing pure permanent gases in an industrial setting.
