Spot tests, the most common of preliminary screening tests, have been of long-standing use in forensic analysis. With the advent of technological instrumentation, the importance of this utilitarian, albeit basic, test procedure has diminished. In the early development of currently accepted laboratory technique, the spot test (also referred to as the color test) was often employed as a conclusive method for substance identification. Advanced technology has demonstrated that color tests alone… 
Colour quantitation for chemical spot tests for a controlled substances presumptive test database.
TLDR
Two of the state-of-the-art apps for reporting the colour test results quantitatively in red-green-blue (RGB) format are evaluated and the compiled library database of presumptive test results contains over 3300 data points including over 800 unique drug/test combinations.
Color tests for the preliminary identification of methcathinone and analogues of methcathinone
The preliminary identification of methcathinone and analogues of methcathinone presents a new and growing challenge to law enforcement. Color tests remain an important tool for the preliminary
Forensic Chemistry/Controlled Substances
This chapter provides an overview of the operation of the forensic chemistry section, specifically, as applied to the analysis of controlled substances. The first section walks the reader through the
A novel method for the presumptive identification of heterocyclic amines of forensic interest using photoluminescent copper(I) iodide cluster compounds
The use of color tests for the presumptive identification of illicit substances has been an important tool used by law enforcement to establish probable cause for decades. However, recently color
Further studies on spot tests and microcrystal tests for identification of cocaine.
TLDR
The data obtained indicated that nine of the 17 compounds gave results similar to those from cocaine using the three spot tests, but that the results from microcrystal testing allowed for differentiation of all nine compounds from cocaine.
Microcrystal Tests for Detection of Nicotine in Hookah Bar Samples
Microcrystalline test is hardly used in forensic science laboratory for the confirmation of drug or alkaloids present in the plants. Therefore an attempt was made to identify and confirm the presence
A REVIEW OF EXPLOSIVE RESIDUE DETECTION FROM FORENSIC CHEMISTRY PERSPECTIVE
The growing threat of terrorism activities has caused an urgent need of improved forensic explosive analysis. Complex matrices, limited samples, and ambiguous interpretations serve as challenges for
