Generally, stable environmental isotopes are measured as ratios of the two most abundant isotopes of a given element. The absolute abundance ratio of isotopes is not usually measured in natural waters because it requires sophisticated mass spectrometric technique.

The relative abundances of the mass spectra 1 – 16 are given in Table 2. In the electron ionization mass spectra all of the studied compounds are observed the corresponding molecular ions, where the abundance ratio of the isotopes of selenenium is characteristic [4].

This study also serves to investigate whether the 2090 Å line is free of line-blends, so as to be useful for future studies with improved instrumentation of the abundance ratio between the two boron isotopes 10 and 11. This ratio is also sensitive to which mechanism(s) were important in the early galactic production...
