The Extreme Ultraviolet Imaging Spectrometer on board the Japanese Sun Observing Satellite “Hinode” realizes the highest sensitivity ever achieved in the two EUV wavelengths of 17-21 nm and 25-29 nm. EIS will be able to provide the detailed diagnostic information on solar corona and transition region. A new tool of timedependent collisonal-radiative model will be developed to analyze the data taken by this EIS instrument, and to diagnose temperatures and densities of those plasmas in the outer atmospheres of the Sun.
