Five-Tube MPN Test. Use Table 1 to determine MPN/100 mL for 5-tube MPN tests. Example: if 4 of the 5 tubes showed a positive response, the MPN/100 mL would be 16.0. Table 3, illustrates typical decimal dilutions for various sample types.

Der 5-Röhrchen-MPN-Test wird von der U.S. Environmental Protection Agency (USEPA) nicht anerkannt. Probengröße Nicht-Trinkwasser Für die Untersuchung von Nicht-Trinkwasser- und Abwasserproben ist es erforderlich, eine Reihe von Röhrchen mit geeigneten Dezimalverdünnungen der ursprünglichen Probe zu beimpfen, die auf der wahrscheinlichen ...

The test uses an incubation temperature at 25 - 35 °C. Therefore, an incubator is not required. The test is well-suited for monitoring drinking water systems in developing tropical countries, in remote field locations, and in disaster or emergency situations. PA and MPN type analyses can be run using PathoScreen™.

In order to test percent chlorine, a hypochlorite test kit will need to be used. There are two different test kits available: Hypochlorite Test Kit, Model CN-HR (Product # 2687200) Hypochlorite Test Kit, Model NC-HRDT (Product # 2687100).

When using the Formaldehyde Test Kit, Model FM-1 (Product # 2183100), formaldehyde in the sample reacts with sodium sulfite from the Formaldehyde 1 reagent and releases hydroxide ions, which raises the sample pH. Sulfuric acid lowers the pH and changes the thymolphthalein indicator from blue to clear.
