We present far UV and optical spectroscopic data of the suspected CP star HD207538.

FUSE observation (range 1000 - 1200 , R = 16000) and optical spectra obtained with the high resolution spectrograph (SARG) of the Italian "Telescopio Nazionale Galileo (TNG)" (range 4600 - 7000 , R = 144000) have been combined.

A spectroscopic analysis has been performed, with Kurucz codes, in order to better define the chemical peculiarity of this object with particular reference to abundance stratification.

As part of our fundamental analysis we also studied the gas-phase ISM content of that line of sight. From the analysis of these ISM lines we deduced a stellar + ISM model of the line of sight in the FUV.
