| Abstract: | The range of the two techniques of multi-element atomic fluorescence spectrometry may be extended by the use of a twinport power divider to allow two multi-element electrodeless discharge lamps to be operated from a single microwave generator. Various combinations of 1/4-wave, 3/4-wave resonant cavities and an A-antenna in conjunction with a coaxial attenuator allow lamps of differing excitation requirements to be operated simultaneously. |
