The TruMac N Macro Determinator analyzes macro samples (up to 3 grams) with minimal cost-per-analysis and rapid analysis times. A horizontal ceramic combustion system using pure oxygen with a maximum temperature of 1450oC ensures the complete oxidation of macro samples. Large reusable ceramic boats ease the sample handling process and allow for ash removal after every analysis. An autoloader provides for the unattended analysis of up to 50 solid or liquid samples. The TruMac complies with AOAC, AACC, AOCS, and ASBC methods of analysis.
