This application note describes the extraction of a panel of 19 steroid hormones from human serum using EVOLUTE® EXPRESS ABN solid phase extraction plates prior to LC/MS analysis. The simple sample preparation procedure delivers clean extracts and analyte recoveries greater than 80% with RSDs lower than 10% for the majority of analytes. Linearity of >0.99 is achieved for all analytes in the range 5–5000 pg/mL.

This application note describes the extraction of a panel of steroid hormones from human serum using ISOLUTE® SLE+ Supported Liquid Extraction plates prior to LC/MS-MS analysis. The simple sample preparation procedure delivers clean extracts and high, reproducible recoveries (>75%, RSD <10% ) for all analytes in human serum, with linearity >0.99 in the range 5–5000 pg/mL.

This application note describes a simple supported liquid extraction method for extraction of estrone and estradiol from human serum. An analytical HPLC-MS/MS method that avoids the use of derivatization or fluoride adduct stabilization (two approaches often used to enhance method sensitivity) is used.
High, reproducible analyte recovery and low detection limits (0.001 ng/mL) are achieved.
