Latest company news about How Lumino can be used to detect bloodstains in criminal investigation cases

For many people, blood detection are far away from us. Everyone only sees the relevant detection process on TV, but many people certainly do not know that there is a chemiluminescent reagent behind the success of the detection. It is luminous ammonia luminol. The murderer often uses various methods to clean up the scene after the murder. When the scene is processed until the blood can not be found by the naked eye, it is necessary to rely on the luminol reagent to investigate the scene.

 

In fact, in the early twentieth century, benzidine was a commonly used reagent for detecting blood stains, but because benzidine and its salts are both toxic and carcinogenic substances, their solids and vapors are easy to enter the body through the skin, so this The method is gradually deprecated, and it is now banned in many countries such as China and the United States.

Then there was a comer. In the 1830s, German crime scene experts unintentionally discovered that Lumino would produce fluorescence after contact with blood. Later, Western countries began to study the mechanism. Until now, Lu Mino reagent has become the most widely used star reagent in blood stain survey in various countries.

 

Even if the blood at the crime scene has been wiped or cleared, forensics can still use Luminol to find their location. In fact, the investigator sprayed the luminol and activator solution in the area to be investigated, and the iron in the blood immediately catalyzed the luminescent reaction of luminol, causing it to produce a blue light. The amount of catalyst required for this reaction is very small, so Luminol can detect traces of blood. The glow lasts about 30 seconds.

 

Lumino is widely used in criminal investigation, bioengineering, chemical tracing and other fields. It is precisely because of its magical effect that it is sought after by many criminal investigation enthusiasts. The professional manufacturer of chemiluminescent reagents includes not only luminol, but also isoluminol, acridinium ester and other products, welcome to contact us for further consultation~!
