Title: METHOD AND EXTRACTION KIT FOR DETERMINING CONCENTRATIONS OF AROMATIC AND ALIPHATIC AMINES IN DIFFERENT MATRICES
Abstract:
The present invention relates to an analysis kit and an extraction method for determining concentrations of aromatic and aliphatic amines in different matrices. According to the invention, the analysis kit comprises an adsorbent consisting of [0.1 to 2g] of NaCl, [0 to 1g] of diatomaceous earth and [0.1 to 10g] of Na2SO4, of a solvent chosen among the organic solvents (toluene, dichloromethane, ether, hexane, etc.) or any other solvent known for its power to dissolve said amines, such as water. And an internal standard chosen among (naphtalene-d8, 2, 4, 5-trichloroaniline, 4-anthracene-d10]. The kit enters into the method, in particular by the adsorbent at the solid-phase extraction step. The method is characterized by a low implementation cost and a very high yield in relation to prior art methods.
