CHNS Determination in nutraceutical products by flash combustion

The term nutraceutical is a combination of nutritional and pharmaceutical. This refers to constituents naturally present in foods and medicinal plants that are attributed to positive effects on human health and a preventive role for one or more diseases, only when proven by scientific evidence. That is why it is important to check the purity of nutraceutical ingredients and products throughout the process of CHNS analysis, also to maintain high product quality.

Routine determination of Total Organic Carbon (TOC) and Total Nitrogen (TN) in environmental samples

Total Organic Carbon (TOC) is a key parameter for assessing soil quality in agriculture, evaluating ecological risks from organic contaminants, and classifying waste for landfill disposal. Determined in compliance with international standards like ISO 10694 or EN 15936, the so-called "direct method" eliminates inorganic carbon with acid treatment before accurately measuring TOC via dry combustion.
