Short Communications


The possibility of forming silyl derivatives of methyprylon and pyrithyldion following an alternative and time-saving procedure is discussed. The derivatives are formed on the needle tip of an all glass solid injector. The linearity and reproduciblity of their gas chromatographic behaviour on a capillary column is tested over a concentration range of 0.5 μg −2.5 μg.
