I already know how a spectroscope works, but does the sample have to be in vacuum?
In other words, if the unknown element is heated to incandescence IN AIR, will the oxygen, nitrogen, etc, cause spectral lines that will appear along with the ones of the element-to-be-identified? If so, does that make it a great deal more difficult to identify the unknown element?
No speculation, please. "probably" and "I think" are useless and will get no points. If you know, tell me, and please also provide your source of info.

When you run a "blank" the instrument records the wavelengths of air, and subtracts those from the spectrum of the sample.
