This application note describes the extraction of a panel of 19 steroid hormones from human urine using EVOLUTE® EXPRESS ABN solid phase extraction plates prior to LC-MS/MS analysis. The simple sample preparation procedure delivers clean extracts and analyte recoveries greater than 75% with RSDs lower than 5% for most analytes. Linearity of greater than 0.999 is achieved for all analytes in the range 1–1000 pg/mL.
Manual and automated (using Biotage Extrahera) extraction protocols are detailed.
