Técnicas de identificación de sustancias sujetas a fiscalización en muestras biológicas dentro del peritaje químico forense

Abstract

This investigative work compiles information on "Techniques for the identification of substances subject to control in biological samples within the forensic chemical expertise"; For many years the traffic, possession and excessive consumption of illicit substances has been considered a global health and social problem. The present investigation begins by generalizing the most important aspects of the substances subject to control, likewise, it aims to establish the techniques with greater scientific validity used by the forensic chemical expert for the identification of these substances in biological samples, and thus the results obtained can form part of the evidence presented to the court of law. The forensic chemical expert is in charge of carrying out these procedures, starting from the collection of the samples in situ to the identification of the substances in the laboratory. When reviewing validated scientific documents and current regulations, it was determined that there are indicative tests and confirmatory tests, the latter are analytical methods, techniques that have greater scientific foundation and validity, in addition, they can be coupled to the mass spectrometry technique to increase reliability and accuracy of results; Therefore, it is concluded by stating that the research meets the hypothesis and objectives set.
