We report elemental abundance studies ultraviolet gallium CP star HD168733. It is neither a silicon, nor a mercury-manganese star and a longitudinal magnetic field of the order of -594 gauss has been detected in it. The high resolution spectra were obtained with the EBASIM spectrograph attached to the 2.10 m telescope at CASLEO Observatory. The abundances results obtained show that Si is normal, Ti, Cr and Fe are rich, PII, SII, GaII, SrII, YII, ZrII are present and its abundances are being determined. The presence of Re will be also investigated.
