Abstract: Knowledge of plasma composition is very important for various plasma applications and prediction of plasma properties. We use the Saha equation and Debye length equation to calculate the non-local thermodynamic-equilibrium plasma composition. It has been shown that the model to 2 T with T representing the temperature (electron temperature and heavy-particle temperature) described by Chen and Han [J. Phys. D 32 (1999) 1711] can be applied for a mixture of gases, where each atomic species has its own temperature, but the model to 4 T is more general because it can be applicable to temperatures distant enough of the heavy particles. This can occur in a plasma composed of big- or macro-molecules. The electron temperature T e varies in the range 8000*20000 K at atmospheric pressure.
