Abstract

The acaricide tricyclohexyltin hydroxide (cyhexatin) was determined in animal feed samples, using gas chromatographic--mass spectrometry in the electron impact mode. Sample extraction and derivatization (converting the analyte to an alkylated derivative) were performed using a tricyclopentyl analogue of this acaricide as internal standard to obtain a better analytical precision.
