✦ Synopsis
and Cu-I lines with an extended inductively-coupled plasma (ICP) torch. In most cases, the relationships were different from those found in previous studies with a conventional short ICP torch. In some cases, unexpected double maxima or minima occurred. A study of the effect of an easily ionized element, potassium, on the fluorescence at the Ca-I and Ca-II lines with the extended-sleeve torch showed a considerably larger ionization interference than exists with the conventional short torch. The extended torch has found some use in laser-excited fluorescence and ICPexcited fluorescence, but researchers should be wary of unexpected variations with power and substantial ionization interferences. aOn leave from Institute of Chemical Metallurgy,
