Title (EN) PROCESS FOR THE QUANTITATIVE DETERMINATION OF ALKALOIDS SUCH AS COCAINE IN A SOLID SAMPLE AND REAGENT FOR USE IN SUCH PROCESS
(FR) PROCEDE PERMETTANT LA DETERMINATION QUANTITATIVE D'ALCALOIDES, TELS QUE LA COCAINE, DANS UN ECHANTILLON SOLIDE, ET REACTIF A UTILISER DANS CE PROCEDE
Abstract:
(EN) A screening-type process for the quantitative determination of cocaine and other alkaloids which are present in a solid sample and a reagent for use in the process. The process includes the steps of providing a solid sample in a finely divided or powdered form; completely immersing the sample into a liquid reagent providing a constant concentration of hydroxyl groups; maintaining the sample immersed in the liquid at a temperature in a range from 10 to 250°C for a period of time in a range from a few seconds to 48 hours; and analyzing the liquid separated from the solid with a conventional kit for the determination of the said substances in urine. The reagent is a liquid that provides a constant concentration of hydroxyl groups in the range of from 0.04 to 0.33 M and comprises 0.2 M (NH4)2HPO4 with the addition of 5 ml of 25 % NH4OH for each liter thereof.
(FR) L'invention concerne un procédé de type criblage permettant une détermination quantitative de cocaïne et d'autres alcaloïdes présents dans un échantillon solide. L'invention concerne également un réactif à utiliser dans le procédé. Ce dernier consiste à fournir un échantillon solide sous une forme finement divisée ou pulvérulente, à immerger totalement ledit échantillon dans un réactif liquide fournissant une concentration constante de groupes hydroxy, à maintenir l'échantillon immergé dans le liquide à une température comprise entre 10 et 250 °C au cours d'une période de temps allant de quelques secondes à 48 heures, puis à analyser le liquide séparé du solide au moyen d'un kit traditionnel afin de déterminer la présence des substances précitées dans l'urine. Le réactif est un liquide fournissant une concentration constante de groupes hydroxy comprise entre 0,04 et 0,33 M et comprenant 0,2 M de (NH4)2HPO4 ajouté de 5 ml de NH4OH 25 % pour chaque litre dudit liquide.
