Abstract
A solenoid serves for generating a magnetic field at the location of a sample which is to be atomized in an atomic absorption spectrometer. A shift of the absorption lines of the atoms in a sample relatively to the emission lines in a measuring light beam (18) passed through the atomized sample is effected by the magnetic field due to the Zeeman effect. The solenoid (44) comprises a pair of pole pieces (46, 48) between which an air gap is formed. An atomizing device atomizes the sample within this air gap. Field coils generate a magnetic flux through the pole pieces (46, 48), the air gap and a magnetic return path (76). The field coils (60, 62) are arranged on pole pieces (46, 48) close to the air gap. The windings of the field coils (60, 62) are formed by tubes (216) which are designed to permit passage of a cooling liquid therethrough.
