The Non-Destructive and In-Situ Identification of Controlled Drugs and Narcotics
7 Aug 2013Over the past few years, Raman spectroscopy has become recognized as an efficient and powerful analytical tool in the field of forensic science. Raman spectroscopy is advantageous as it is non-contact, non-destructive and does not require any sample preparation. This application note reviews the main advantages of the technique for drug investigation and illustrates them with a specific study of cocaine and its derivatives.

Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available.

Forensic genetic instruments, kits and reagents enable the analysis of evidence collected at the crime scene. Reagents and kits for presumptive analysis for body fluids such as blood, saliva and semen in addition to drugs and narcotics test kits are used for CSI. Fingerprinting equipment, forensic light sources, casting kits and equipment for collecting recoverable materials can be found in the directory.Toxicology / Drugs of Abuse TestingToxicology and Drugs of Abuse Testing is the investigation into toxic and illegal substances found at the scene of a crime or from a suspect and / or victim associated with a scene of a crime. Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.BiochemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.CocaineDrugs of AbuseA drug of abuse is a drug that has been taken for non-medical purposes. Such drugs can have mind-altering effects, with some causing dependence and addiction.Forensic InvestigationForensic investigation is a diverse collection of scientific techniques and methods for the identification and characterization of chemicals relating to crime scene investigations.
