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