Copper concentrate is an important raw material for copper mills. The concentrate is often contaminated with corrosive fluorine, which is why the fluorine concentration must be checked at regular intervals. A convenient and reliable determination method is Combustion IC in combination with sacrificing vial technology. The sample is placed inside the quartz combustion pipe in a horizontally positioned quartz vial, both ends of which are sealed with glass wool. During combustion, the quartz-destroying components (e.g., fluoride, alkali and earth alkali metals) that are released are captured by the quartz vial and the quartz wool, ensuring that they are thus unable to reach the quartz combustion pipe at all.
