LECO 828 Series: Macro Combustion Analysis for Carbon, Hydrogen, Nitrogen, and Protein Determination

The 828 Series macro combustion analyzer from LECO is the industry-leading solution for carbon, hydrogen, nitrogen, and protein determination. Featuring state-of-the-art hardware and an intuitive touch-screen software platform: Cornerstone®, the 828 Series is designed to handle a wide range of sample applications with ease, making it the perfect fit for laboratories with diverse analysis needs.

Built on the trusted performance of previous generations of LECO macro combustion instruments, the 828 Series offers significant improvements in throughput, uptime, and reliability, ensuring that your lab operates at peak efficiency. With rapid cycle times as fast as 2.8 minutes and the ability to handle macro sample masses, this instrument is built for high-volume testing with unmatched sample analysis throughput.

For even more versatility, all 828 Series models are compatible with the S832 add-on, enabling independent sulfur determination, expanding the range of analyses your lab can perform.

LECO 828 Series Applications:

The 828 Series is ideal for a wide variety of applications across industries, including:

• Feeds, Pet Foods, Grains and Cereals
• Milled Products
• Protein-based Products including Fermentation Products, Dairy Whey and Cheese Products
• Soils, Sediments, Fertilizers, Plant Tissue
• Waste Materials, Resins and Polymers, Coal and Coke, Biomass Materials
• Petroleum Products and Additives

How the LECO 828 Series Works:

The 828 Series uses a combustion technique with a vertical quartz furnace to determine nitrogen/protein, carbon/nitrogen, and carbon/hydrogen/nitrogen in diverse organic matrices, including food, feeds, soils, and fuels.

• Samples are automatically weighed into a tin capsule or encapsulated in tin foil and loaded into the 828 Series analyzer.
• The sample undergoes a fully automated analysis sequence, first entering a sealed purge chamber to remove atmospheric gas.
• After purging, the sample is transferred to the furnace, where it is combusted in an oxygen-rich environment for rapid oxidation.
• Depending on the model, gases from the furnace are analyzed for carbon (CO2), nitrogen (N2), and in the CHN828 model, hydrogen (H2).
• For sulfur analysis, the CHN828 model includes an afterburner to scrub sulfur compounds from the gas stream before it is analyzed.

This process ensures superior throughput while maintaining the precision and reliability that LECO is known for.
