The combustion in pure oxygen and the proven so called “Ballast — Aliquot” principle results in a matrix independent analysis, high sample throughput and low analysis costs, for a range of sample weights in the gram range. According to the company the reduction reagent can last for up to 4000 analyses.

For a complete CHNS analysis you can expect analysis times of ~ 4 minutes, and Nitrogen only analysis can take just 2.8 minutes. Argon or Helium can be used as inert carrier gas. The high temperature sulfur module (up to 1450 °C) is perfect for complete Sulfur analysis, also with samples containing a lot of sulfates or moisture. An autosampler with 120 positions is available for high sample throughput.

The system is controlled by the intuitive, self-explaining Leco cornerstone touch screen software running on a Windows 10 PC. The use of control and check routines care for easy maintenance and reliable analysis results.
