Development and validation of a High performance liquid chromatography-Mass spectrometry method for 17 a -methyltestosterone in Aquatic water systems
Journal Title: Journal of Applied and Natural Science - Year 2010, Vol 2, Issue 2
Abstract
17 a -Methyltestosterone is used as feed additive to manipulate the gender of fish for aquaculture. Earlier a simple, yet specific and robust validated high performance liquid chromatographic method has been developed for the determination of 17 a -methyltestosterone in fish feed. The present work describes a highly sensitive and robust Liquid Chromatography-Mass Spectrometry method for the quantitation of 17 a -methyltestosterone in aquatic water systems using 17 β -hydroxy-3 β -methoxyandrost-5-en-7-one as internal standard. The method was validated in the concentration range of 0.2 to 25 ng of 17 a -methyltestosterone on column leading to a limit of quantitation of 0.08 ppb or 0.08 mg/L in water, and has potential to increase the limit of detection and quantitation by an order of magnitude, if required.
