The simple answer and the summery is\u0080\u00a6 We are what we eat and the stable isotopes signature in our bodies represents our diet and eating behavior.<\/p>\n<p>The <a href=\"https:\/\/www.thermofisher.com\/de\/en\/home\/industrial\/mass-spectrometry\/isotope-ratio-mass-spectrometry-irms\/isotope-fingerprinting.html\" target=\"_blank\" rel=\"nofollow noopener\">isotope fingerprint<\/a>, found in plants, for example, can vary according to plant type, but also according to region or rainfall. By eating those plants, carbon, hydrogen, and other elements are taken up by our bodies and converted into our own body tissue. Our own isotope fingerprint resembles therefore the fingerprint of our nutrition. Similarly, isotope fingerprints of our naturally produced steroids equals the isotope fingerprint of our body tissue. However, synthetic steroids do not! So, if the athlete is clean, stable isotope composition should remain identical among all steroids in his body. But if the athlete was taking synthetic testosterone, we will be able to see a difference in stable isotope value in the testosterone sample.<\/p>\n<p>Check out this whiteboard video about doping control with stable isotopes to get a great overview of how isotope analysis works.<\/p>\n<p><iframe loading=\"lazy\" title=\"Doping Control with the Isotope Hunter\" width=\"760\" height=\"428\" src=\"https:\/\/www.youtube.com\/embed\/C3NCCBmZGoU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/p>\n<p>The analysis of testosterone misuses in sports is usually done with carbon isotopes (<sup>13<\/sup>C\/<sup>12<\/sup>C). Here, samples of testosterone are collected from urine and analyzed after sample preparation. <a href=\"https:\/\/www.thermofisher.com\/de\/de\/home\/industrial\/mass-spectrometry\/isotope-ratio-mass-spectrometry-irms.html\" target=\"_blank\" rel=\"nofollow noopener\">Isotope-ratio mass spectrometry (IRMS)<\/a> is the analytical technique for stable isotope analysis in organic compounds. In contrast to the standard mass spectrometry, as in example <a href=\"https:\/\/www.thermofisher.com\/de\/en\/home\/industrial\/mass-spectrometry\/gas-chromatography-mass-spectrometry-gc-ms.html\" target=\"_blank\" rel=\"nofollow noopener\">quadrupole MS or Orbitrap MS<\/a>, IRMS is capable of measuring the smallest differences in the isotope composition with high accuracy. And this is quite important since differences in isotope ratio occur in per mill range. Therefore, too small to detect with a standard MS.<\/p>\n<p>The IRMS is usually coupled to a gas chromatography (GC) or liquid chromatography (HPLC) for a prior separation of a compound mixture. Especially, this is useful for biological and environmental samples.<\/p>\n<p>Achieving the high accuracy isotope composition can only be measured after online compound conversion to a simple analyte gas &#8212; i.e. carbon to carbon dioxide. Carbon dioxide retains the isotopic information and is subsequently analyzed with IRMS with high precision.<\/p>\n<p>However, we must take into consideration the destructive nature of the methodology. To achieve the high accuracy, isotope composition can only be measured after online compound conversion to a simple analyte gas &#8212; i.e. carbon to carbon dioxide.

Identification of steroid metabolites in complex matrices can be time-consuming and challenging due to the requirement to both identify and quantify hundreds of different compounds with limited prior knowledge of the metabolites. Here compound-specific stable isotope analysis can be used to provide insights into the metabolism of many compounds in plants, animals and humans. Deuterium labeling of compounds has long been recognized as a valuable means to identify metabolites. GC-IRMS enables the compound-specific hydrogen isotope analysis at natural abundance and deuterium enrichment.
