Preferred label	ALS_UK_HORMONES
Definition	ALS UK Hormones: Determination of hormones in water. The compounds of interst are extracted from filtered aqueous matrix by solid phase extraction (SPE) and the extracts are further cleaned up by means of of another SPE procedure utilising a cartridge with a molecular imprinted polymer (MIP) stationary phase that has a class selective affinity for steroidal oestrogens. The isolated determinands are then derivatised with pentafluorobenzoyl chloride (PFBCI) and MSTFA and analysed by GC-MS-MS with negative chemical ionisation (NCI) using methane as the reagent gas. Quantification is based upon an internal standardisation procedure. ALS Environmental, Torrington Avenue, Coventry, CV4 9GU, United Kingdom
