Applications of the zeeman effect to analytical atomic spectroscopy-VI A comparison of some experimental and theoretical detection limits.
Design details are given for a high-sensitivity Zeeman-modulated spectrometer using commercial hollow-cathode lamp sources. Experimental detection limits are given for 6 elements, and the values compared with theoretical values calculated on the basis of signals limited only by photon noise. Some conclusions are drawn regarding the sensitivity limits accessible to atomic-absorption spectroscopy with present technology.
