K-3925 DEHA Titrets Kit was designed to obtain DEHA levels ranging from 25-250 ppm
Why Choose CHEMetrics Titrets?
CHEMetrics Titrets self-filing reagent ampoules make it easy to perform quick, accurate titrations of water samples. The handheld titrettor that comes with the kit allows the user to easily and reliably control the flow of the solution being measured without the need to count drops or use burets or other equipment. This unique design allows you to perform a titration anywhere and achieve reliable results for a variety of substances.
Safe and Reliable Results
While traditional methods often require multiple steps and thorough preparation, these test kits allow you to obtain dependable results with a few simple steps. By simplifying the testing method, Tritrets test kits reduce the potential for operator error. Additionally, each of the ampoules contained in the test kits is vacuum sealed which helps eliminate the problem of obtaining inaccurate results from stale or unstable reagents. These reagents are stored right in the tip of each ampoule and sealed in glass, thereby minimizing direct contact with the chemicals.
The K-3925 DEHA Kit was designed to accurately measure the levels of DEHA in water from 25-250 ppm. K-3925 uses the Ceric Sulfate Titrant with Ferroin Indicator Method. CHEMetrics developed a titrimetric method that employs a ceric sulfate titrant and ferroin end point indicator. DEHA reduces ferric iron to the ferrous state, and the resulting ferrous iron is titrated with the ceric sulfate titrant. Test results are expressed in ppm (mg/L) DEHA.
Dissolved oxygen in boiler system water causes corrosion and pitting of metal surfaces, which can lead to boiler inefficiency, equipment failure, and system downtime. DEHA (N,N- Diethylhydroxylamine) is added to boiler system water as an oxygen scavenger to keep the dissolved oxygen levels as low as possible.
How to use:
Note: Images used in the following table show a total hardness and colors may differ from the ones shown. Read written instructions to know what color changes to expect from your substance.
|1. Fill the sample cup to the 15 mL mark with the sample to be tested.||2. Add 6 drops of the Activator Solution. Stir to mix the contents of the cup. Wait 2 minutes the sample will turn orange.|
|3. Snap the tip of the ampoule at the black snap ring.||4. Lift the control bar and insert the Titret assembly into the Titrettor.|
|5. Hold the Titrettor with the sample pipe in the sample. Press the control bar firmly, but briefly, to pull in a small amount of sample. The contents will turn green.||6. Press the control bar again to draw another small amount of sample into the ampoule.|
|7. Rock the entire assembly to mix the contents of the ampoule. Watch for a color change from blue to colorless. Repeat steps 6 and 7 until a permanent color change occurs.||8. When the color of the liquid in the ampoule changes through blue to a brownish-orange, remove the ampoule from the Titrettor. Hold the ampoule tip pointed upward and read the scale opposite the liquid level. Results are expressed in ppm
