| dc.description.abstract | Testosterone, androstenedione and 17-hydroxyprogesterone are powerful steroids which play a critical role in development and reproductive processes in men and women. The quantitative determination of serum steroids is mandatory in the investigation of suspected disorder of excessive and insufficient steroid production in adults and delayed puberty in adolescents. While immunoassays are the general analytical method, for accurate and reproducible quantification of such analytes liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is gaining importance. Advantages are its unparalleled specificity and sensitivity combined with the very practical potential for multi-analyte quantification. Prior to any analysis by LC-MS/MS a suitable sample clean-up is essential to efficiently remove matrix components such as proteins, lipids, carbohydrates and salt which may interfere with the analytical procedure. The Tecan AC Extraction PlateTM is an ingenious novel consumable: a 96-position, deep-well microplate featuring TICETM (Tecan Immobilized Coating Extraction) technology. The inner surface of each well is coated with a specific volume of sorptive material to approximately half the well’s height. The TICE coating acts as the extractant, eliminating the need for protein precipitation, liquid separation steps or the generation of emulsions. It is the basis for a simple and automatable approach to the preparation of biological samples without the need for offline operations. In parallel an automation for SLE+ plates from Biotage was set up on the same Tecan liquid handling system for comparison. | de_CH |
