Why Choose CHEMetrics Chemets kits?

CHEMetrics Chemets self-filing reagent ampoules are a great way to test for dissolved substances in liquids. These visual test kits allow you to obtain results by measuring the color of the sample according to the color comparators provided with the kit. This unique method allows you to attain results quickly and accurately with minimal contact with potentially hazardous materials.

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, Chemets 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.

What's included:

  • 30 self-filling Ampoules
  • low and high-range comparators 
  • 1 25 mL Sample Cup
  • Activator Solution
  • 1 mL syringe
  • Instruction Manual

Method

The K-3902 DEHA Kit was designed to accurately measure the levels of DEHA in water from 0-400 and 400-3000 ppb. K-3902 uses the PDTS Method. The test kits employ the PDTS chemistry, in which DEHA reduces iron III (ferric state) to iron II (ferrous state), which readily reacts with PDTS (3-(2-pyridyl)-5,6-bis(4-phenylsulfonic acid)-1,2,4-triazine disodium salt) to form a pink-purple colored complex in direct proportion to the DEHA concentration. Test results are expressed in ppb (ug/L) or 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.

R-3902 Refill Package includes 30 tests and can be purchased separately.

 

1. Fill the sample cup to the 25 mL mark with the sample to be tested. Add 2 drops of Activator Solution. Stir to mix the contents of the cup. 2. Immediately place the Vacu-vial ampoule tip-first into the sample cup. Snap the tip and the ampoule will automatically fill.
3. To mix the ampoule, tilt it from side to side, allowing the bubble to travel from end to end. 4. Dry the ampoule and wait 10 minutes for color development.
5. Place the ampoule into the center of the round comparator and hold it toward a source of light, viewing from the bottom. Rotate the comparator until the color below the ampoule shows the closest match. 6. For higher concentrations, use flat comparator. Place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
