K-1520C Ammonia

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-1510C test kit.

The K-1520C Ammonia HR CHEMets^® Test Kit (1000-10,000 ppm) comes in a plastic case and contains everything needed to perform 30 tests (except distilled water): 30 HR CHEMets^® ampoules, a color comparator, fixed volume pipet, 25 mL sample cup, and instructions.

This kit is applicable for wastewater, environmental, aquaculture or any application where high concentrations of ammonia may be found in water.

Shelf life: Although the Nessler reagent is stable, its high alkali content attacks the glass ampoule. The resulting precipitate interferes with color comparison. The refill has a 5-month shelf life when stored in the dark and at room temperature. This shelf life can be extended by 18 months if the refill is refrigerated.

What's Included:

Method:

The Ammonia CHEMets®1 test kit employs direct nesslerzation.2,3 In a strongly alkaline solution, ammonia reacts with Nessler Reagent (K2 Hgl4 ) to produce a yellowcolored complex in direct proportion to the ammonia concentration. This method is applicable to drinking water, clean surface water, good quality nitrified waterwater effulent and seawater. Other types of samples may require a preliminary distillation step. 

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