DETERMINATION OF HEROIN HYDROCHLORIDE CONTENTS IN SEIZED SAMPLES BY GAS CHROMATOGRAPHIC TECHNIQUES

Abstract

Heroin is a dangerous drug that is used worldwide. In Thailand, it is classified as a drug that has seen an increase in arrests. An accurate and reliable method for determining the precise amount of illicit drugs is essential, as courts of law depend on analytical results to ensure fair judgments. The objective of this work, determination of heroin hydrochloride contents in the seized drugs were obtained by Gas Chromatography-Flame Ionization Detector (GC-FID). The samples used for analysis were the drugs seized in the regions of Ratchaburi province during summer of 2023 (April -September). In this experiment, the validation of GC-FID methods was accomplished. It was found that the heroin hydrochloride contents in all samples were in the range of 70-88% w/w (SD = 0.35, % RSD = 0.43). The results from this study revealed that the GC-FID method was suitable for analysis of the heroin hydrochloride contents in seized drugs in forensic applications.
