A chemical abundance analysis is made of two F type high proper motion stars selected from the \sc ELODIE library. We use high resolution (R=42 000) and high signal to noise ratio (S/N=103, 36 -per-pixel) échelle spectra from the \sc ELODIE library of HD 102870 and BD +20 3603, as two representative F type high proper motion stars, to determine fundamental parameters and photospheric abundances of 16 chemical elements including slow (s)- and rapid (r)-process elements from Y to Ba. The chemical composition and kinematic parameters of the stars imply that they belong to different Galactic populations: we report HD 102870, an IAU standard radial velocity star, to be a thin disk star and BD +20 3603, a metal-poor HPM star, to be a halo star.
