Uses of Argon gas
Q. Why only argon gas is used in optical emission spectrometer? Kindly reply to this question.

A. It's probably something to do with: In spectroscopic analysis it has some properties that are similar to Helium or Hydrogen. Look up optical emission spectroscopy abstracts --
Argon is inert, cheap, readily available.
Argon based spectrum analysis tools for the metallographic analysis are already available by some pioneer industries like Leco.

A. Following are the reason why Argon Gas used in Optical emission Spectrometry.
1.Argon gas is inert in nature. When it is flushed in Sparking area, air gets removed. Sparking gets improved due to non-existence of air.
2. Molecules of Argon gas are bigger which also improves sparking.
3. Argon is easily available and cheap.

Onkar,
Argon is a gas, not a type of spectroscopy. I imagine you are referring to optical emission spectroscopy, which USES argon gas, as referred to above.
I'm not sure what your current level of knowledge is here. If you are well versed in physics you should get the idea quickly from this and the related articles:

If you are not well versed in physics then something written more for a layman audience is
