This Laboratory contains a Fritsch Pulverisette 7 micro mil for sediment grinding and a LECO TruSpec Micro CHNS that simultaneously measures the weight % of carbon, hydrogen, nitrogen and sulfur present in sediments. This instrument uses micro samples and is controlled via a computer with specific software.
To quantify the organic elements present in marine sediments is a basic requirement to estimate marine primary production at any one time, as well as to define the origin of the organic material.
