LECO’s TruMac CNS Macro Analyzer adds sulfur analysis capabilities (suited for soil and plant tissue analysis) to the instrument’s existing carbon/nitrogen configuration. Macro sample sizes (up to 3 g for nitrogen; 1.5 g for carbon/nitrogen; 0.3 g for carbon/nitrogen/sulfur) are quickly and simultaneously analyzed with a low cost per analysis. A horizontal ceramic combustion system, using pure oxygen, with a maximum temperature of 1450 C ensures the complete oxidation of macro samples. Large, reusable ceramic boats make the sample handling process easy to manage, and allow for ash removal after every analysis. An autoloader provides unattended analysis of up to 50 samples. By adding sulfur capabilities, the analyzer becomes a suited choice for those looking to analyze macro samples in the environmental and agronomy markets. The unit complies with AOAC-, AACC-, AOCS-, and ASBC-approved methods of analysis.
