D)All of the above

Question

Quizplus · Accepted Answer

All of the options listed are commonly used as screening tests for explosive residues. Color spot tests are quick and simple chemical tests that can indicate the presence of explosive materials. Thin-layer chromatography (TLC) is a method used to separate and identify compounds, including explosives, based on their movement on a stationary phase under the influence of a solvent. Gas-chromatography-mass spectrometry (GC-MS) is a more sophisticated technique that separates chemical substances and identifies them with high specificity and sensitivity, making it highly useful for the analysis of explosive residues.
