摘要：
Systems and methods are disclosed that include adjusting a pressure level of a sample gas in a testing chamber, for example, using a pressurized inert reference gas, and determining a composition of the adjusted sample gas. By adjusting the pressure level of the sample gas, the composition of the sample gas may be determined more accurately than otherwise possible. Numerous other aspects are disclosed.
