Does steam contain air or oxygen?

Ask for advice: Does the steam contain air or oxygen?
There should be no oxygen in the steam, and boilers are equipped with deaeration equipment.
The steam should contain oxygen, and there should be sampling after the boiler deaeration equipment. The question of how much
Even if there is oxygen in the steam, there is only a trace amount, because the oxygen content of the boiler water is less than 7 ppb after being deaerated by the deaeration equipment.
The water on the boiler has a very small amount of dissolved oxygen, so there will be some in the steam as well.
Strictly speaking, steam is composed of water vapor, but because boiler desalted water contains trace amounts of dissolved oxygen, steam also contains trace amounts of oxygen within the allowable range.
The concept of air is too big. There should be no air in steam, and it contains very little oxygen.
According to your explanation, can I understand that steam is mainly water vapor after water vaporization, containing a trace amount of oxygen, and there should be no other components?
It can be said that there is no oxygen, but there may be trace amounts of oxygen,
Are there any other inert gases?
The boiler feed water is deoxygenated water. The deoxygenating process is a steam stripping process. All oxygen has been stripped out.
