Therefore, the scope of this paper is mainly concerned with inorganic Fe isotope fractionation in the modern seafloor hydrothermal systems.

The isotopic transformations involving the relative abundances of heavy and light isotopes are called fractionations, and they occur because lighter isotopes form chemical bonds that require less energy to break.

In addition, it is difficult to obtain trustworthy interpretations of isotopic data because it requires understanding the isotopic fractionation that occurs between the diet and the consumer, as small organic changes affect trophic level estimations and the contributions of different producer sources (McCutchan et al., 2003).

In a second series of experiments, the same resin was isolated in ethyl lactate (EL) and a similar series of fractionations were run with the new fractionation method.

The new fractionation method resulted in higher yields of resins with comparable or improved functional properties when used in i-line sensitive (365 nm) photoresist formulations.

Results from some fractionations by the CRYSTAF-method were kindly delivered by Dr.

In a recent paper (22) we found that segregation fractionations performed by DSC can give valuable qualitative information about the comonomer distribution in Z-N-copolymers but also, that this technique can be applied on metallocene copolymers.

Using final tissue-diet isotopic differences in the two largest juvenile groups for the FP diet, the fractionation values were estimated as 1.6 [per thousand] and 2.2 [per thousand] for [delta] [sup.13]C and [delta] [sup.15]N, respectively.
