 |  | The Chemical Analysis Process
| | Spectroscopy - October 1, 2008 | The process of chemical analysis consists of several steps, beginning with the taking of the sample and followed by sample preparation. The sample is subjected to the analytical method and we arrive at a result (Figure 1). |
|  | The Role of Naturally Occurring Stable Isotopes in Mass Spectrometry, Part I: The Theory
| | Spectroscopy - October 1, 2008 | | In this tutorial, the authors explain how naturally occurring stable isotopes contribute to experimentally determined mass spectra and how this information can be exploited in quantitative experiments, structural elucidation studies, and tracer methodologies. The first installment of this series focuses on the theoretical aspects of stable isotopes and the calculation of their distribution patterns. |
