K-8012C Phenols

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-8012C Phenols Kit was designed to accurately measure the levels of Phenols in water from 0-1000 ppm and 0-13,000 ppm. K-8012C uses the 4-Aminoantipyrine Method. CHEMetrics' phenols kits employ the well-established 4-aminoantipyrine (4-AAP) method. Phenolic compounds react with 4-AAP in alkaline solution in the presence of ferricyanide to produce a red reaction product. Phenol, meta-, and ortho-substituted phenols, and some para-substituted phenols, under proper pH conditions, are detected with this method. The method is applicable to the monitoring of phenolic compounds in wastewater. Results are expressed as ppm (mg/L) phenol. 

Phenol (hydroxybenzene) is the simplest of a group of similar organic chemicals, which includes cresols, xylenols, and catechols. Phenol itself is a common ingredient of disinfectants. In drinking water, low-level phenolic concentrations impart a foul taste and odor, especially upon chlorination. High phenol concentrations can indicate contamination from industrial effluents or waste discharge.

1. Fill the diluter snapper cup to the -ml- mark with distilled water. Dissolve the crystals on the tip of the ampoule by stirring for 10 seconds with the ampoule tip.	2. Fill the 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.
