Maximized Laboratory Productivity

Benefit: Increase lab throughput and reduce turnaround time, enabling faster, more efficient sample analysis.
Reason to Believe: The 828 Series boasts rapid cycle times as fast as 2.8 minutes (for FP/CN models), allowing your lab to process more samples in less time.

Unmatched Reliability and Uptime

Benefit: Minimize downtime and ensure continuous operation, maximizing your lab’s productivity and reducing the need for frequent repairs.
Reason to Believe: With extended reagent lifetimes, the 828 Series reduces the frequency of maintenance while ensuring optimal performance, keeping your lab running smoothly without interruptions.

Reduced Maintenance and Operational Costs

Benefit: Cut maintenance time and costs, enabling your team to focus on higher-value tasks.
Reason to Believe: Easy access to common maintenance areas streamlines routine maintenance, and the reagent-free furnace design lowers operational costs by eliminating the need for costly reagents and minimizing maintenance time.

Increased Sample Capacity and Efficiency

Benefit: Process more samples with less effort, improving your lab’s efficiency and throughput.
Reason to Believe: The rugged 30-sample autoloader (with optional capacity for up to 120 samples) enables hands-free operation, ensuring consistent high-volume analysis with minimal manual intervention.

Operator-Centered Design for Improved Usability

Benefit: Enhance operator comfort and ease of use, leading to fewer errors and higher operator satisfaction.
Reason to Believe: The ergonomic, boom-mounted touch-screen interface allows operators to control the system from a comfortable standing position, reducing strain and improving ease of use.

Superior Furnace Efficiency

Benefit: Achieve reliable, efficient analysis with minimal downtime and maintenance.
Reason to Believe: The 828 Series furnace is designed for maximum efficiency and reliability with its reagent-free design, ensuring consistent high-quality results without the need for costly consumables.

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

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.
