The chemically peculiar star HR 1094 has been investigated with respect to its chemical composition and the magnetic influence on its stellar spectrum. By using spectral lines slightly affected by the field v sin i was determined to be <= 17 km s-1. The iron-group elements as well as chlorine and the heavy elements platinum, gold and mercury show an overabundance compared to the sun. The analysis also revealed the rare earth elements to be present from lines of their second and third spectrum. Based on observations obtained with the Nordic Optical Telescope, operated on the island of La Palma jointly by Denmark, Finland, Iceland, Norway, and Sweden, in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias.
