Abstract
A method and system for controlling the concentration of one or more gaseous species of interest in a sample medium throughout a range of temperatures in which a temperature related, time variable 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 sample medium in a manner such that the concentration of the gaseous species of interest in the sample medium remains essentially the same over the temperature range. The source of the gaseous species of interest comprises a reservoir containing an amount of a temperature sensitive source of the gaseous species of interest. The sample and the reservoir are contained in separate fluid-tight, gas-permeable enclosures further confined by a common substantially gas-tight enclosure.
