Abstract
Androgenic anabolic steroids are the most misused substances in sports because of their performance-enhancing effects. Often synthetic analogues of endogenously present steroids are administered. To determine their endogenous or exogenous origin, Gas Chromatography Combustion Isotope Ratio Mass Spectrometry (GC-C-IRMS) is used in the field of doping control. Compounds subjected to IRMS analysis must be interference-free, with liquid chromatography fraction collection (HPLC-FC) being the crucial clean-up step. This clean-up is challenging, particularly for compounds present at low concentrations in samples with pronounced matrix effects. Currently, the available methods only deal with a selection of the compounds mentioned above. Some of these compounds (e.g., 19-NA, B, BM, 6aOHADION) are present in very low concentrations, requiring an extensive sample clean-up, making it challenging to develop a universal clean-up procedure. Many of these methods require different and multiple offline HPLC-FC set-ups, which can be labour-intensive and time-consuming. That is problematic during, e.g., large sports events, where reporting time is limited to 72 hours. Therefore, we developed a uniform online 2D/3D HPLC-FC method (set-up described in Figure 1), capable of purifying all relevant target compounds in a single run, leading to the fastest clean-up procedure so far (i.e., 31 min for T and its main metabolites; 46 min for 19-NA, F and 6aOHADION; 48 min for B and BM). A satisfactory clean-up was demonstrated by the excellent accuracy obtained during the analysis of certified samples and EQAS samples. This method was fully compliant with WADA requirements with LOQs of 2 ng mL for 6aOHADION-Ac, B-Ac, BM-Ac and 19-NA-Ac and of 10 ng mL for T-Ac and its metabolites and F-Ac. This work demonstrates the possibilities of multi-dimensional HPLC as an automated multi-target sample preparation methodology and how finding an optimal set-up allows pushing analytical instruments to their maximal capabilities.
