We keep the library up-to-date, so you may find new or improved material here over time. 2 dagar sedan · \(\textit{A}_\textup{r} = 35.5\) (to 1 decimal place) Notice that the answer is closer to 35 than it is to 37. This is because the chlorine-35 isotope is much more abundant than the chlorine-37 Normally, IRMS analysis of drugs of abuse involves the determination of the relative isotope abundances of hydrogen (1 H and 2 H), carbon (12 C and 13 C), nitrogen (14 N and N 15), and oxygen (16 O, 17 O, and 18 O). The terrestrial isotope ratios were determined when the earth was formed and are, for the most part, fixed. These isotopes are radioactive in nature and are, therefore, known as radioisotopes (or radionuclides). Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238.
