K-6010B Iron

Why Choose CHEMetrics Vacuettes kits?

VACUettes ampoules are designed for highly concentrated samples. They employ a patented auto-dilution feature that eliminates the need for a time-consuming and error-prone preliminary dilution. As a result, the entire test takes only 2 to 3 minutes, with a rate of accuracy comparable to a volumetric procedure. The basic design of these 7 mm ampoules is the same as CHEMets ampoules, however, a capillary tip is attached to the tip of each ampoule.

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, Vacuettes 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:

Method:

The K-6010B Iron Kit was designed to accurately measure the levels of soluble and total Iron in water from 0-120 ppm and 120-1200 ppm. K-6010 B uses the Phenanthroline Method. With the Phenanthroline method, ferrous iron reacts with 1,10-phenanthroline to form an orange-colored chelate. To determine total iron, thioglycolic acid solution is added to reduce ferric iron to the ferrous state. The reagent formulation minimizes interferences from various metals. Results are expressed as ppm (mg/L) Fe.

Iron is present in nature in the form of its oxides, or in combination with silicon or sulfur. The soluble iron content of surface waters rarely exceeds 1 mg/L, while ground waters often contain higher concentrations. The National Secondary Drinking Water Standard for iron is 0.3 mg/L, as iron concentrations in excess of 0.3 mg/L impart a foul taste and cause staining. High concentrations in surface waters can indicate the presence of industrial effluents or runoff.

1. Fill the diluter snapper cup to the -ml- mark with distilled water.	2. Fill the small micro-test tube approximately halfway with the sample to be tested.
3. Holding the VACUette almost horizontally, touch the tip to the contents of the micro-test tube.	4. Place the VACUette between the vertical tip guides on the inside of the dilutor snapper cup and snap the ampoule tip.
5.To mix the ampoule, invert it several times, allowing the bubble to travel from end to end.	6. Dry the ampoule. Obtain the test result 1 minute after snapping the tip.
7. 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.	8. 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.
