A Chemical Oxygen Demand (COD) test is used to measure the amount of organic compounds in a water sample. It measures the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrate. The most common method of COD testing is where a water sample is pipetted into a COD vial that contains pre-measured re...

Testing for Sodium is often required in food or blood samples. Some water samples may need to be tested, particularly those where a softening system is used. Due to the nature of sodium's chemistry, it cannot be tested by a simple test kit method. We've taken a look at why this is, and explored what options are available for testing sodium.

Spectrophotometers are relied on by a wide range of laboratories, for tests ranging from specific parameters, like chlorine or metals concentrations, right through to complex analyses of reaction kinetics. When choosing a spectrophotometer the range of specifications and price is vast, so take the time to list the features you need before you buy and make sure you choose the right one. [c...
