Hose material, pipes, and storage tanks in the dairy industry are often cleaned and disinfected using compounds containing active chlorine, such as alkaline hypochlorite. However, excess chlorine remaining on surfaces can lead to the formation of chloroform, which remains as an impurity in the milk. Chloroform is a toxic compound that damages the liver, heart, and other organs, so it must be detected immediately.
Background
Solution
Real-time measurement of chloroform is achieved by using V&F's patented IMR-MS technology. No time-consuming sample preparation is required, nor do samples have to be taken. Direct measurement in the gas space above the milk within a tank provides an immediate result and facilitates a quick decision.
The IMR-MS is very selective in measuring chloroform in milk. Due to its technology, it avoids any kind of time-consuming sample preparation and provides a fast and reliable measurement of chloroform in milk in real-time by analyzing the gas space above the milk.
Advantages
Currently, gas chromatography (GC) is routinely used to determine residual chloroform in raw milk. This method is comparatively slow and can take up to 10 minutes before a result is provided. It is also limited to spot testing and random measurement. In contrast, V&FIMR-MS provides extremely accurate results within seconds with the ability to economically and continuously measure multiple batches as well as tubes and the ambient space for potential chloroform contamination.
