How long does the Luminol light last?

In crime scene investigations, forensic scientists rely on a variety of tools and techniques to gather evidence and solve crimes. One such tool is Luminol, a compound that emits a blue light when in contact with blood or other substances containing hemoglobin. Luminol is an important part of countless investigations, helping to find hidden bloodstains and increasing the visibility of evidence at crime scenes.

A renowned brand in this field, D&S offers quality chemiluminescent reagents that simplify the investigation process. With cutting-edge technology and extensive research, it ensures that important clues are not missed. In this article, we will delve into the topic of how long luminescence lasts, revealing the practicality and effectiveness of DeSung's luminescence solutions.

The Science Behind Luminol Luminescence

To understand how long Luminol can last, you must first understand the scientific principles behind its unique luminescence. Luminol glows when it chemically reacts with the iron in hemoglobin. However, this process is not instantaneous. It requires the presence of an oxidizing agent, such as hydrogen peroxide, to trigger the reaction. Therefore, the duration of luminex luminescence depends on several factors, including the concentration of luminex, the presence of an activator, and the quality of the luminex solution itself.

Factors affecting the luminescence duration of lumineau

Tecsun's lumineau solution pays attention to details during the preparation process, taking into account the key factors that determine the duration of luminescence. The concentration of lumineau plays an important role in the length of luminescence duration. Higher concentrations of Luminol produce a longer lasting luminescence, thereby increasing the chances of detecting blood at challenging crime scenes. In addition, the presence of an activator (usually hydrogen peroxide) accelerates the reaction, resulting in a brighter and longer lasting luminescence.

Chemiluminescent reagent products

Desheng is committed to providing high quality chemiluminescence reagent products, its luminal series contains luminal, isoluminal, luminal monosodium salt, and acridine ester series has 6 different groups, acridine salt, acridine hydrazide, acridine ester. DeSheng has perfected the chemiluminescence reagent products to maximize the luminescence time of lumino without affecting the accuracy.

The specific luminescence time of Luminol

The whole luminescence process of Luminol usually lasts for about 30 seconds.1 Usually, the luminescence process will be shortened rapidly when the alkalinity is too strong, the concentration of alkali is too large or the concentration of hydrogen peroxide is too large. Therefore, if you want to increase the duration of luminescence, you can optimize the above factors to prolong the luminescence process, and control the above factors can make the whole luminescence process last for 5-10 minutes.

The duration of luminescence depends on various factors, such as concentration and presence of activator. It has been proved that the chemiluminescence reagents of D&S have quite high sensitivity and stability. If you need high quality chemiluminescence reagents, Desheng should be your first choice brand.
