Fluorescent FLT Yellow/Green Dye

These fluorescent dyes provide a higher degree of environmental safety and can be used on potable water.

Bright Dyes FLT Yellow products are specially formulated versions of Rhodamine WT dye for convenient use in water tracing and leak detection studies. This bright, fluorescent dye is certified by NSF International to ANSI/NSF Standard 60 for use in drinking water. It may be detected visually, by ultraviolet light and by appropriate fluorometric equipment. Today it is most often used visually.

Fluorescent FLT Yellow/Green Dye One fluorescent yellow/green tablet in 60 gallons of water gives a strong visual concentration of 1 ppm, or one tablet in 600 gallons of water will give a light visual concentration of 100 ppb. Tablets dissolve in five to eight minutes.

Dye tracing products are used in many analytical applications. The unique needs of our customers seem almost unlimited. Some of the most common uses are:

– Plumbing tracing
– Flow mapping and rate of flow studies
– Power plant piping tracing
– Pollution studies
– Lake, river and pond analysis
– Storm & sewer drain analysis
– Retention time studies
– Condenser coil and tube studies
– Septic system analysis
– Leak detection in many fluid carrying systems
– Checking for illegal connections
– And many more

The dye is resistant to absorption on most suspended mater in fresh and salt water.

How Fluorescent Dye Tracing Products Work:
The “visual” aspect of Bright Dyes products refers to normal reflection of light as color. The “fluorescent” aspect refers to special properties of some chemicals to absorb certain wavelengths and then emit, rather than reflect, light in response. The emission can be seen by using a “black” ultraviolet light or precisely measured with a fluorometer. The reflected and emitted light have different wavelengths and are, therefore, not the same color.

Light stability
Blue has the highest degree of light stability and red is recommended for yellow and green backgrounds such as algae rich water. FLT Yellow/Green should be used in water bearing heavy sediment loads or when passing through soil with high clay content. Industrial Red will absorb onto either. Photo degradation takes place in sunlight at different rates for different dyes. Red takes from approximately five to seven days and yellow/green fades in two to three days. Blue, on the other hand, breaks down in three to four weeks.

The color of all dyes will disappear if the solution is mixed with chlorine. Add approximately 4 grams of 12% bleach to every gram of product in solution.
