Risk Reactor's IFWB-C7 Visible Fluorescent Red tracer is a specially formulated version of Rhodamine WT dye for convenient use in water tracing and leak detection studies. This bright, fluorescent red dye is certified to ANSI 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. Visually the dye appears bright pink to red, depending on its concentration and under ultraviolet light as bright orange. The dye is resistant to absorption on most suspended mater in fresh and salt water. Compared to our IFWB-C6 Yellow/Green product, it is significantly more resistant to degradation by sunlight and when used in fluorometry, stands out much more clearly against background fluorescence. As always the use and 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 Standard 60 for potable water as set forth by the EPA in The Clean Water Act.

Note: Risk Reactor's IFWB-C7 Red has the highest degree of light stability and is recommended for yellow and/or green backgrounds, such as algae rich waters. Sandy soil will not absorb our Red or yellow green. Color is visible in clear water at one part per million.

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 measured 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.

The maximum Absorbance/Emission Wavelengths of Our Products are:

Product Color: Red

Absorption Emission: 550 nm 588 nm  

What Does PPB Mean? Most of our products contain fluorescent dyes, which can be detected visually, or with the use of ultraviolet light or fluorometer. As used in Risk Reactor literature, "ppb" refers to one part of active dye per billion parts of water. Using a fluorometer, the active dye can often be detected at levels less than one ppb. All data is presented as reference points only and should not be regarded as a recommendation. Users should make their own determination of appropriate dilution levels in any specific situation, which will vary with the nature, condition, and use of the water or liquid and the specific evaluation to be performed.

For Stream Tracing and Pollution Detection: Introduce tracers into the water at the source or suspected source of pollution. Allow sufficient time as calculated, to permit the dye tracer to reach the effluent or recipient location. Take samples of water for analysis.

Dye Tablets: May be dropped or flushed directly into drains, sewers or other points in the system. However, it may be desirable to dissolve them in a small amount of water to form a calculated concentration prior to use. Special larger shapes (cakes cones, and donuts) have been designed to provide optimum dissolution rates in large systems. Donuts are frequently suspended from a line or string into the body of water. Cakes and donuts are sealed in a handy water-soluble film for ease of use.

Light Stability: Red is recommended for yellow and green backgrounds such as algae rich water. Red, blue, and 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.

Examples of Specific Projects: Test sewer lines for infiltration. Locates sewer lines. Check for illegal connections. Prove septic bypasses. Identify indirect cross-connections. Check drain pipes, downspouts, and gutters to assure drainage into proper channels. Use in inspection service for certification and reinspection documentation. Analyze travel times. Toilet leak detection kits are frequently used by plumbers, municipalities and utilities use them as part of public relations and water conservation programs. Detect leaks in closed systems and cooling systems of steel manufacturers. Study infiltration and industrial water piping systems. Trace acid coming though cooling systems. Check pump systems flow in fleet trucks, and for preventative maintenance programs. Detect sewer leaks into ponds, lagoons, and reservoir lines. Check circulation through sludge beds and to measure discharge flow from water tanks. Illustrate the hydraulic characteristics of streams and other water bodies. Identify and differentiate batches of slurry before the brick firing process. Measure the speed and longevity of material passing through a system (i.e. retention time studies).
