A short reaction time (60 ms) and a rapid separation of the reaction products is obtained by mixing the acidi®ed sample and the sodium borohydride reductant solution at the tip of a cross-¯ow nebuliser. A modi®ed Scott spray chamber serves as a gas±liquid separator, providing 30 s wash-in and wash-out times. Analytical results generated by external calibration and isotope dilution methodologies agree well with the certi®ed values for Se in certi®ed biological reference materials DORM-2 and DOLT-2. Detection limits for Se and other hydride forming elements, i.e., As, Sn and Sb, are below 10 ng l 21 with typical precision of 2% RSD at the 10 ng ml 21 level. Volatile species o...

“…More recently, the aim of CHG has been expanded to an increasing number of elements, including In [20], Tl [21,22], Cd [23], Cu [24], Zn [25,26], and many other transition metals such as Ni, Co, Cr, Fe, Ti, and the noble metals Au, Ag, Pd, Pt, Ir, Os, Ru, and Rh [27,28]. The nature of the volatile reaction products obtained from CHG of transition and noble metals has not been yet identified; as well, CHG of these elements has found limited analytical applications [24,29] in comparison with the classical hydride-forming elements.…”

Aqueous-phase chemical generation of volatile hydrides (CHG) by derivatization with borane complexes is one of the most powerful and widely employed methods for determination and speciation analysis of trace and ultratrace elements (viz. Ge, Sn, Pb, As, Sb, Bi, Se, Te, Hg, Cd, and, more recently, several transition and noble metals) when coupled with atomic and mass spectrometric detection techniques. Analytical CHG is still dominated by erroneous concepts, which have been disseminated and consolidated within the analytical scientific community over the course of many years. The overall approach to CHG has thus remained completely empirical, which hinders possibilities for further development. This report is focused on the rationalization and clarification of fundamental aspects related to CHG: (i) mechanism of hydrolysis of borane complexes; (ii) mechanism of hydrogen transfer from the borane complex to the analytical substrate; (iii) mechanisms through which the different chemical reaction conditions control the CHG process; and (iv) mechanism of action of chemical additives and foreign species. Enhanced comprehension of these different mechanisms and their mutual influence can be achieved in light of the present state of knowledge. This provides the tools to explain the reactivity of a CHG system and contributes to the clarification of several controversial aspects and the elimination of erroneous concepts in CHG.
