Why Choose HR CHEMets kits?

HR CHEMets®  is the new way to test at high ranges and replaces the now discontinued VACUettes product line. This product's measurement ranges overlaps with the discontinued K-5510B test kit. 

Included:

     -30 self-filling Ampoules

     -Comparator 

     -Diluter snapper cup

     -Micro test tube

     -Instruction Manual

Method:

The Hydrogen Peroxide CHEMets®1 test method employs theferric thiocyanate chemistry.² In an acidic solution, hydrogen peroxide oxidizes ferrous iron. The resulting ferric iron reacts with ammonium thiocyanate to form ferric thiocyanate, a red/orange colored complex, in direct proportion to the hydrogen peroxide concentration.
Ferric iron and peracetic acid (PAA) will produce high test results. Cupric copper also interferes with the test. Testing for peroxide in the presence of PAA or cupric copper requires a modified test procedure.

 

1. Place a pipette tip firmly onto the end of the MiniPet®4 (fig. 1). Note: Use a fresh pipette tip for each test.  2. Depress the plunger on the minipet. Immerse the tip in the sample to be tested and release the plunger. A portion of the sample will be drawn into the tip (fig. 2).
3. Hold the minipet over the empty sample cup, and depress the plunger to dispense sample (fig. 3). 4. Dilute the contents of the sample cup to the 25 ml mark with distilled water (fig. 4). 

5. Add solutions to the sample cup in the following order (fig. 5).

5 drops S-1404 Stabilizer

5 drops S-1405 Catalyzer (green)

5 drops S-1406 Activator (blue)

6. Immediately place the CHEMet ampoule, tip first, into the sample cup. Snap the tip. The ampoule will fill leaving a bubble for mixing (fig. 6).

To mix the ampoule, invert it several times, allowing the bubble to travel from end to end. Dry the ampoule. Obtain a test result  5 minutes after snapping the tip.  

7. Obtain a test result by placing the ampoule between the color standards until the best color match is found (fig. 7).

NOTE: Use the concentration scale on the comparator label that corresponds to the range of the test procedure being used.

0 - 10,000 ppm Test Procedure

  1. Using the syringe provided, obtain 3 mL of the sample to be tested and dispense it into the empty Sample Prep Cup.
  2. 2. Dilute to the 15 mL mark with distilled water. Perform the entire 0 - 2000 ppm Test Procedure using this pre-diluted sample.
