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.
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.

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.
Luminol was first used for murder investigations in the early 20th century. It was introduced by forensic scientists in the 1930s as a method for detecting traces of blood at crime scenes that may not be visible to the naked eye.
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.
If the temperature is cold then the luminol will have a brighter excited state than if the temperature was hot or room temp.

The concentration of the luminol stock solution is approximately 22.7 M.
The basic idea of luminol is to reveal blood traces with a light producing chemical reaction between several chemicals and hemoglobin.

The chemical reagent that makes blood glow luminously is luminol. When it reacts with the iron present in hemoglobin, it produces a blue light that is visible in dark conditions. Luminol is often used in forensic investigations to detect blood at crime scenes.
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.
