Title:
同位体比の分析方法および装置
Document Type and Number:
Japanese Patent JP5153763
Kind Code:
B2
Abstract:
The process involves supplying a sample gas and a reference gas to an analyzer over an opened coupling (22), where the coupling has capillaries with different cross-sections. The concentration of the sample gas and/or reference gas is regulated through automatic, electronic flow regulation of the carrier gas, where the carrier gas flow is regulated in such a manner that the concentration of the sample gas and/or the reference gas is constant. An independent claim is also included for a device for supplying gases to an analyzer.
