Influence of heating rate on analytical response in flameless atomic absorption spectrometry

Factors controlling the shape and position of the absorption curves at the electrothermal rod atomizer. Comments

“…In this occurrence a simple direct proportionality which could exist between N(t) and S(i), is lost and recourse to an integral of the kind described in Equation 1 becomes necessary. For this reason our earlier model (7), which Zsakó refers to, has been superseded by a more sophisticated approach (2). In this respect we agree completely with him that the linear relationship between peak height absorbance, and heating rate which we proposed in our earlier model (7), is only a simplified picture of the actual situation.…”

Alteration of metal release mechanisms in graphite furnace atomizers by chemisorbed oxygen

“…The widespread employment of graphite furnace atomizers and the need to develop a better understanding of the basic atomization processes have led to a number of studies employing both mathematical modeling and theoretical mechanisms for atom formation and loss (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). A likely process preceding atomization would involve the reduction of a metal oxide by the graphite atomizer.…”

“…The problem of fluorescence interference in Raman spectrometry has led to many attempts to reduce this residual background (1)(2)(3)(4)(5)(6)(7)(8). In general, two experimental approaches have been taken to reduce the background interferences.…”

Optical system for gathering simultaneous time and spatial data from transient events

“…For this purpose, it is useful to follow the time-dependent analytical signal after atomization and examine where and when it is affected by added interferents. In addition to the interference problem, the development of a satisfactory model describing the atomization process itself is desirable (8)(9)(10).…”
