This test measures the total concentration of Cobalt, a naturally occurring mineral that is part of vitamin B12. Low levels of Cobalt have been shown to increase fermentation performance. At high levels, Cobalt is considered a contaminant and investigation may be needed in order to prevent undesirable levels. Cobalt concentration may increase due to bentonite being used as a technological aid for clarification purposes as well as the attack of alloys during filtration. Cobalt can also show increased levels based on geographic region and industry.
