Title (EN) HUMAN HAIR DECONTAMINATION PROCESS
(FR) PROCÉDÉ DE DÉCONTAMINATION DE CHEVEU HUMAIN
(PT) PROCESSO DE DESCONTAMINAÇÃO DE CABELO HUMANO
Abstract: front page image
(EN)The present invention relates to a human hair decontamination process for drug abuse investigation, using non-volatile liquids. This extraction methodology is based on the negligible vapour pressure of these liquids (e.g. ionic liquids), and on their capacity to act as absorbents. It is a simple and reliable method that makes it possible to remove all contaminants from the hair surface, thus eliminating the problem of false positives, in particular in cases when no drugs were consumed, but without any physical contact between the hair and the liquid.
(FR)La présente invention concerne un procédé décontamination de cheveu humain utilisé dans la détection de drogues, faisant appel à des liquides non volatils. Cette technique d'extraction se base sur la pression de vapeur négligeable de ces liquides (par ex., liquides ioniques), ainsi que sur leur capacité à agir comme agents d'absorption. Il s'agit d'une méthode simple et fiable permettant d'éliminer tous les contaminants de la surface du cheveu, ce qui permet de supprimer le problème des faux positifs, notamment dans les cas où aucune consommation n'a eu lieu, sans aucun contact physique entre le cheveu et le liquide.
(PT)A presente invenção diz respeito ao processo de descontaminação de cabelo humano usado na pesquisa de drogas de abuso, recorrendo a líquidos não voláteis. Esta metodologia de extracção baseia-se na pressão de vapor negligenciável destes líquidos (e.g. líquidos iónicos), assim como na sua capacidade de actuarem como agentes de absorção. Trata-se de um método simples e fiável que permite remover todos os contaminantes da superfície do cabelo eliminando assim o problema dos falsos positivos, em especial nos casos onde não houve consumo, sem no entanto haver qualquer contacto físico entre o cabelo e o líquido.
