SUMMARY A simple modification to an electronic O 2 analyser is described which enables accurate determination of O 2 in small gas samples. The response to O 2 concentration is linear over the range 0–21% by volume and as little as 0.07 μl of O 2 can be detected. Analysis of a 25 μl sample takes 25 s.
