If the temperature is cold then the luminol will have a brighter excited state than if the temperature was hot or room temp.
In Season 6, Episode 7 of CSI: Crime Scene Investigation titled "A Bullet Runs Through It, Part 1," luminol is used to detect blood in a crime scene. The forensic team sprays luminol on a crime scene and discovers blood spatter patterns that help them piece together what happened.
Investigators may spray a crime scene with hydrochloric acid (HCl) before using luminol to help remove any potential contaminants or residues that could interfere with the reaction of luminol with blood. This ensures a clean surface for the luminol to detect any hidden blood traces effectively.
The concentration of the luminol stock solution is approximately 22.7 M.
Luminol is a common chemical used to detect blood at a crime scene. It reacts with the iron in hemoglobin, causing a blue glow under UV light. This can help investigators identify blood even if it has been cleaned or hidden.
Forensic scientists test blood at a crime scene using the chemicals Luminol (C8H7N3O2) and hydrogen Peroxide (H2O2). if blood is present when they use these chemicals, it will glow with a bluish color in the dark. I hope this helps.
They eat them!
Luminol is a common reagent used at crime scenes to identify blood. When sprayed, it reacts with the iron in hemoglobin to produce a blue luminescence, making any bloodstains visible even if they are not easily seen with the naked eye.
