Abstract:

A new 9-mm i.d. inductively coupled plasma torch is described which supports a stable, analytically useful plasma at less than 500 watts of r.f. power and 7 Lmin total argon gas flow. Detection limits, working curves and other analytical characteristics of the new device are compared with those of both a miniature 13-mm i.d. and conventional 19-mm i.d. ICP. Although temperatures of the new plasma are somewhat lower than those in the larger plasmas, the new system offers promise for future, miniaturized ICP instruments. Author
