LECO introduces the new 812 series carbon and moisture determinator

LECO has launched the new 812 Series, a next-generation analyser designed for the rapid and reliable determination of carbon and moisture in a wide range of organic and inorganic materials. Combining enhanced sensitivity, faster thermal performance, and programmable multi-atmosphere operation, the system delivers deeper insight into material composition while simplifying laboratory workflows. In addition to the determination of total carbon and total moisture, the system uses a thermal differentiation approach to separate and quantify individual carbon and moisture phases based on their release temperature profiles, providing valuable insight into material behaviour and composition.

The 812 Series features an efficient horizontal furnace design with improved active cooling and optimised temperature control, reducing cycle times by up to 50% compared with previous-generation systems. The platform provides simultaneous carbon and moisture determination while eliminating the need for labour-intensive or hazardous chemical preparation. Enhanced detector performance delivers up to a tenfold improvement in carbon detection limits and a twentyfold improvement in moisture sensitivity, enabling analysis of increasingly challenging low-level applications.

Key Improvements

• Up to 50% faster ramp-up and 30% faster cool-down times for increased laboratory throughput.
• Up to 10× lower carbon detection limits and 20× lower moisture detection limits for demanding applications.
• Programmable furnace operation with oxygen or nitrogen atmospheres and fixed or ramped heating profiles.
• Improved accessibility through front- and side-entry design combined with intuitive Cornerstone^® software.

Four Key Application Areas

• TOC Analysis (Soil & Waste Materials)
  Differentiation of TOC, ROC, and TIC for environmental monitoring, soil characterisation, carbon sequestration studies, and waste analysis.
  LECO is hosting a TOC Workshop at the EATC in Berlin on 24–25 November, with the new CM812 as one of the key topics. Find out more and register here.
• Surface Carbon Measurement
  Direct temperature-based determination of residual hydrocarbons, oils, and lubricants on cleaned metal surfaces to verify cleaning effectiveness and reduce downstream defects.
• Moisture in Welding Fluxes & Consumables
  Rapid measurement of free and bound moisture to help prevent hydrogen-induced cracking, improve weld quality, and support compliance with AWS and ISO standards.
• Moisture in Metal Powders
  Sensitive moisture analysis for powder metallurgy and additive manufacturing materials to minimise porosity, oxidation, and variability in finished components.

Customer Benefits

The 812 Series combines faster analyses, improved detection limits, and advanced phase characterisation on a single platform, helping laboratories increase productivity, simplify workflows, and achieve more reliable results.

With compliance to standards including ISO/EN 17505, EN 15936, ISO 10694, and AWS A4.4M, the 812 Series provides laboratories with a versatile solution for carbon and moisture analysis across environmental, manufacturing, welding, and advanced materials applications.
