| | Does anyone have working LC/MS/MS extraction and analysis methods for testosterone and estrogen along with their degradation products (conjugated and unconjugated)? Testosterone methods seem nonexistent, usually done by HPLC-RD or radio immunoassay. Thanks for any and all suggestions! Paige Gay |

Kolpin et al, Environmental Science and Technology, 2002, 36, 1202-1211. It explains in detail the compounds tested for as well as the methodology employed. Here is part of the bibliography: (26) Lindsey, M. E.; Meyer, M.; Thurman, E. M. Anal. Chem. 2001, 73, 4640-4646.(27) Brown, G. K.; Zaugg, S. D.; Barber, L. B. Water-Resour. Invest.
