Dosaje directo de derivados organometálicos por cromatografía gaseosa

Abstract

It was developed a gas chromatographie method, which consists in the hydrolysis of the sample (usually a solution) in a microreactor, attached to a by-pass injector device. This microreaotor consibts in a little trap, filled with concentrated phosphoric acid, placed below the septum ruber. The volatile hydrocarbons produced are introduced by means of the by-pass injector, to a chromatograph equipped with suitable columns and detectors. From the chromatogram the quali and quantitativc composition of the sample can be calculated.
