K-6503 Manganese

Why Choose Vacu-vials?

CHEMetrics Vacu-vials self-filling ampoules are a great way to test for dissolved substances in liquid. Unlike our visual test kits, the Vacu-vials test kit allows you to obtain an instrumental result using the CHEMetrics Direct-Redout Photometers or any spectrophotometer capable of accepting a 13m diameter round cell. When using equipment from another manufacturer, set the spectrophotometer to absorbance mode, select the wavelength specified by the Vacu-vials kit instructions, and follow the test procedure. The K-6503 Manganese Kit was designed to accurately measure the levels of manganese in water from 0-30.0 ppm.

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, Vacuvials 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      -25 mL Sample Cup      -Stabilizer Solutions      -Ampoule Blank      -1 mL Syringe      -Instruction Manual

Method:

The K-6503 uses the Periodate Method. CHEMetrics' tests employ the periodate chemistry that measures soluble manganese compounds but does not differentiate the various valence states. Results are expressed as ppm (mg/L) Mn. Permanganate (MnO₄) develops approximately 25% more color with this reagent than other forms of manganese, causing a high bias. If the sample is known to contain manganese in the form of permanganate only, multiplying test results by 0.8 will improve the accuracy of the results. 

Surface and ground waters rarely contain more than 1 mg/L of soluble or suspended manganese. Manganese can act as an oxidizing or a reducing agent depending on its valence state. Manganese is also used in the manufacture of batteries and as an alloying metal in the manufacture of steel and aluminum. The National Secondary Drinking Water Standard for manganese is 0.05 mg/L, as higher concentrations will impart a foul taste to water and discolor laundry and porcelain surfaces.

How to Use:

1. Fill the sample cup to the 20 mL mark with the sample to be tested.	2. Add 1 mL of the Activator Solution. Stir to mix the contents of the cup.
3. Place the Vacu-vial ampoule tip-first into the sample cup. Snap the tip and the ampoule will automatically fill.	4. To mix the ampoule, tilt it from side to side, allowing the bubble to travel from end to end.
5. Dry the ampoule and wait 1 minute for color development.	6. Insert the Vacu-vial ampoule into the photometer, flat end first, and obtain a reading in ppm.
