oxygen headspace gen.

Добрый день! Подскажите, пожалуйста, как перевести "oxygen headspace" в сертификате анализа лекарственного препарата.
Спасибо!

Probably, it has smth to do with the test facilities used for the analysis, like this:
http://www.systechillinois.com/ru/carbon-dioxide-and-oxygen-headspace-gas-analyzer-gaspace-advance-micro_29.html

If this the case (you can tell after reading about the method and comparing it with your context), look up headspace + gas + analysis + chromatography in various combinations, then try to google out some Russian references in a similar context
