Recently, our team investigated how to optimise the combustion-based methods in this Food Navigator article. “One way is to increase the sample mass, therefore increasing the amount of nitrogen presented to the instrument for detection,” explained Mason Marsh, LECO's Organic Product Manager. “This can also be significantly helpful when analyzing samples that are heterogeneous in nature as well.” But does increasing the sample size affect the precision of the results?
In the article, the analysis process is summarised for our FP828, which is capable of analyzing samples under 1.0 gram and our FP928 which is designed for larger samples over 1.0 gram. A comparison of the data was made to indicate which instrument provided the best and most precise results. Read the article to see how these combustion methods were optimised for low-level nitrogen samples.
