Product Description:
Risk Reactor's IFWB-C8 Yellow Green products are specially formulated versions of Xanthene dye, certified by International to ANSI/ Standard 60 for use in drinking water. This dye is the traditional fluorescent water tracing and leak detection material and has been used for labeling studies from the beginning of the century. It may be detected visually, by UV light and by appropriate fluoremetric equipment. Today, it is most often used visually. This dye has been used by the military to mark downed pilots for search and rescue operations over large water bodies. Visually the dye appears yellow/green, depending on its concentration and under UV light as lime green. Based on biochemical oxygen demand (BOD) studies, the dye is biodegradable with 65% of the available oxygen consumed in 7 days. The dye is resistant to absorption on most suspended matter in fresh and salt water. However, compared to Risk Reactor's IFWB-C7 Red products it is significantly less resistant to degradation by sunlight and when used in fluoremetry, stands out much less clearly against background fluorescence. As always the suitability of these products for any specific application should be evaluated by a qualified hydrologist or other industry professional.

Certified To Meet EPA Standards This is a certification that these products conform to the ANSI/ Standard 60 for potable water as set forth by the EPA in The Clean Water Act.

Note: Our yellow green is recommended for shallow water bearing heavy sediment loads. Sandy soil will not absorb our Red or yellow green. Color is visible in clear water at one part per million.

Benefits of Risk Reactor's IFWB-C8 Yellow Green Water Based Tracer:

  • Most appropriate fluorescent products for quantitative analysis!
  • High strength formulations for medium to large scale visual and fluorometric studies!
  • It is clear when diluted preventing stains and other unwanted marks!
  • Can be detected using one of our (portable battery operated ones available) black lights at significantly lower levels such as in the range of 10 ppb in ideal conditions!
  • Fluoresces under long wave black light!
  • Cleans up with water!
  • Highly concentrated saving you money!
  • Safe and non-toxic!
  • Can be used with our 6" Hand Held Black Light for mobility!
  • Bio Degradable!
  • Can be used with UV sensors for automation!
  • Because of the fluorescent nature, IFWB-C8 offers greater contrast than non-fluorescent tracers!

How to Use:
How Fluorescent Dye Tracing Products Work: The "visual" aspect of our dye 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 measure Yellow Green with a fluorometer. The reflected and emitted light have different wavelengths and are, therefore, not the same color.

Fluorescent Properties are of Greatest Value When :

- Tracing must be done when there is no sun or sufficient artificial light (in a sewer or a cave, for instance)

- Precise quantified data is required

- Very small amounts of tracing material is allowed.
