Chapter 221 Breakthrough

Luminol Reagent is the substance often used in films and television series to reveal the presence of blood.

In earlier years, Luminol had to be mixed on the spot, but now there are pre-packaged products available for use.

Luminol possesses an exceptional ability to detect bloodstains.

How exceptional? Bloodstains from several years ago can be revealed unless they have been specially treated.

Even if blood is diluted a million times, which is to say a drop of blood in a bathtub full of water, it can still be easily detected by Luminol.

Therefore, trying to wash away blood traces with water is practically futile in the face of Luminol.

This is also why it is generally not advised to commit murder within one's home.

Luminol is a very affordable reagent. 0.1 grams of Luminol, combined with 5 grams of sodium carbonate and 6 milliliters of hydrogen peroxide, can produce a 100 milliliters bottle of Luminol solution.
