METHOD FOR ELECTROCHEMICAL DETECTION AND IDENTIFICATION OF DRUGS, NARCOTICS AND PRECURSORS THEREOF

摘要

The present invention relates methods for the electrochemical identification and quantification of drugs, narcotics and its chemical precursors. Specifically, the present invention relates to method for detecting and identifying narcotics, or precursors thereof, in a sample, the method comprises the steps of: a) dissolving a solid or liquid sample suspected to comprise narcotics, or precursors, thereof in a buffer solution comprising electrolytes thereby providing an electrochemically reactive solution; b)transferring the electrochemically reactive solution onto a screen printed electrode sensor provided with a reference, working and counter electrode , the sensor is configured to provide electrochemical interaction between the electrochemically reactive solution and the electrodes; c) transferring the sensor to a portable device capable of voltammetry and equipped with voltammetry analysis and display means; d) subjecting the electrochemically reactive solution to a voltammetric analysis using the portable device with a AV (potential) in the range from -3,000 mV to 3,000 mV and measuring the resulting current (A) in the electrochemically reactive solution; e) plotting the measured current against the applied voltage; and f) detecting and identifying narcotics, or precursors thereof, based on the position of at least two peaks and/or pattern of peaks in the plot. 1043265
