Trotec Uranin – for leak detection or flow path analysis
Classic uranium powder is a marker that has been recognized for many years and is one of the most strongly fluorescent marking dyes.
This UV-fluorescent dye is clearly visible to the naked eye, which is why it is often used to mark bodies of water. When highly diluted, uranium-based powder—which is highly soluble in water—is toxicologically safe and ideally suited for all leak detection and leak testing applications, where the dyed water must penetrate via capillary action, causing moisture to appear with a significant delay after flooding. Even the smallest leaks can be clearly visualized using a UV lamp.
Pure uranium powder or even highly concentrated aqueous solutions are quite dark red in color. They do not fluoresce. Only when highly diluted does uranium cause the water to fluoresce in shades ranging from yellowish-green to green, depending on the dilution. This effect becomes very clearly visible when illuminated with a UV lamp.
Fluorescent substances, known as tracers , have long been used to study underground water flows. They are added to water in appropriate doses, giving it the characteristic color of the respective tracer. Uranine has also been used for this purpose for nearly a century. Pure uranine powder or even highly concentrated aqueous solutions are quite dark red in color. They do not fluoresce. Only at higher dilutions does uranine color the water a fluorescent yellowish-green to green, depending on the dilution. The effect becomes even more pronounced under UV light (365 nm).
Uranium does not adhere particularly well to rocks, which makes it well-suited for studying underground water flow paths.
Its adhesion to many non-porous building materials is also not particularly strong. Since uranine decomposes in daylight within a few days, it can also be used to detect leaks, such as in leaky house walls. However, this property makes it only conditionally suitable for studying and marking surface water, unless this effect is specifically desired.
The Uranin Green marking agent is not suitable for use as a food coloring!
