• These fumes may also come from phthalates and other plastic-softening chemicals (plasticizers) that evaporate (or outgas) over time.

• Carbon dioxide and hydrogen may form from organic materials, moisture is outgassed by polymers and amine-cured epoxies outgas ammonia.

• Normal copper is unsuitable for high vacuum as it is difficult to outgas completely.

• Failed insulation will also typically outgas, which can lead to process contamination.
