Powder/Granulates

Hydrocarbons are also involved during the production of various powders and granulates (such as pesticide, tinder). Depending on the process, the measurement of hydrocarbon concentration is significant during production or final inspection. A relatively time-consuming laboratory procedure is usually used for this purpose. Due to the high degree of variation in the concentration, several samples normally need to be examined in order to arrive at a definitive conclusion regarding the concentration.

Using KONTAVISOR it is possible to accurately evaluate large quantities of samples within a few seconds. Optionally an online measurement is available.
