Choose from our IFWB Series EPA Approved and N.S.F.(Standard 60) Water Based Tracers in liquid concentrates. Since they are liquid, they are real easy to disperse into any water based system that you want.

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

- Plumbing Tracing.
- Retention Time Studies.
- Flow mapping and rate of flow studies.
- Condenser coil and tube studies.
- Power plant piping tracing.
- Septic system analysis.
- Pollution Studies.
- Leak Detection in many fluid carrying systems.
- Lake river and pond analysis.
- Check for illegal connections.
- Storm and sewer drain analysis.

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	Absorption	Emission
IFWB-C7 Red	550 nm	588 nm
IFWB-C8 Yellow/Green	490 nm	520 nm
IFWB-33 Orange	349 nm	430 nm
IFWB-14 Blue	630 nm	n/a

Note: Blue is for visual tracing only

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.

How to Calculate the Size of a Body of Water?

One gallon of water occupies .1337 cubic feet. For a rectangular tank, multiply depth in feet times width times length divided by the factor .1337 to establish the number of gallons. For more complicated bodies of water, formulas can be found in scientific texts on water utility management, hydrology, etc.

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.

Light Stability:

Blue has the highest degree of light stability and 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.
