In cases where no suspicious substances are observed in the scene of the death, the presence of cyanide in the victim's body can be confirmed chemically using a colorimetric test, followed by a laboratory analysis using a gas chromatography–mass spectrometry (GC-MS).Jan 9, 2012
How can you identify cyanide?
Cyanide can be a colorless gas, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl), or a crystal form such as sodium cyanide (NaCN) or potassium cyanide (KCN). Cyanide sometimes is described as having a “bitter almond” smell, but it does not always give off an odor, and not everyone can detect this odor.
How do you test for cyanide in food?
Overview. Our Cyanide Detectors allow the user to rapidly and easily detect cyanide in drinks and food. Simply place three to five droplets of the prepared sample to the entry port marked on the card and watch for blue color to form if cyanide is present in the sample.
Is cyanide poisoning hard to detect?
Detection of cyanide poisoning can be difficult. The effects of cyanide ingestion are very similar to the effects of suffocation. The mechanism of toxicity occurs because cyanide stops the cells of the body from being able to use oxygen, which all cells need to survive.
Can you detect cyanide in autopsy?
Cyanide was identified and confirmed in biological samples from autopsies and articles left by the deceased in other 163 cases. Concentrations of cyanide in heart blood and peripheral blood. The concentrations of cyanide were determined in biological samples, such as heart blood and peripheral blood (femoral vein).
Can cyanide be traced?
Since cyanide salts are solid crystalline, their presence in a crime scene or in the areas near victim's nose or mouth can be easily discovered, collected and preserved for further forensic testing.Jan 9, 2012
How long after death can cyanide be detected?
Unless cyanide is discovered at the time of death on the mouth or nose, elevated cyanide concentrations can only be found for up to two days under current toxicological testing.Feb 1, 2012
Can cyanide poisoning be cured?
The cyanide antidote kit consists of three medications given together: amyl nitrite, sodium nitrite, and sodium thiosulfate. The amyl nitrite is given by inhalation for 15 to 30 seconds, while sodium nitrite is administered intravenously over three to five minutes.

How does a cyanide detector work? A hydrocyanic gas detector (HCN) is a tool used to determine the concentration of hydrocyanic acid in air. These devices (especially the FD-90A-HCN forensic detectors) have a long battery life, a large display showing the HCN concentration, and a belt clip for attaching to clothing. How are cyanide ions tested?
