Document Type and Number:
Japanese Patent JP3369564
Kind Code:
B2
Abstract:
A method and system for controlling the concentration of one or more gaseous species of interest in a fluid reference medium throughout a range of temperatures in which a temperature related, dominant independent source of the gaseous species of interest is used to control the partial pressure of one or more gaseous species of interest contained in the reference medium in a manner such that the concentration of the gaseous species of interest in the reference medium is controlled as a predetermined, normally generally linear, function of temperature, f(T), over the temperature range. The source of the one or more gaseous species of interest is a separate reservoir containing an amount of a formulated temperature sensitive source of the one or more gaseous species of interest. The reference medium and the reservoir are contained in separate liquid-tight, gas-permeable enclosures contained in a common substantially gas-tight enclosure.
