IMPROVEMENT IN THE LIMITS OF DETECTION IN INDUCTIVELY-COUPLED PLASMA-ATOMIC EMISSION-SPECTROMETRY

A significant improvement in the limits of detection obtained using co mmercially available inductively coupled plasma atomic emission spectr omers has been recently achieved. This improvement can be explained by a better efficiency of the sample introduction system, the use of a h igh practical resolution of the dispersive system, better characterist ics of the hf generator, and the use of the axial viewing mode of the central channel. Actually, this is the combination of the various tech nological changes which has led to an improvement of a factor of 20.
