928 Series Macro Combustion Determination of C, N, S, and Protein
The 928 Series Macro Combustion Determinators are designed for laboratories that routinely analyze heterogeneous, difficult-to-prepare, or low-level analyte samples. The platform supports determination of Carbon/Nitrogen/Sulfur (CNS) and Nitrogen/Protein using high-temperature combustion, delivering reliable results even with challenging macro-scale samples.
Advanced instrument hardware combined with LECO’s exclusive Cornerstone™ touchscreen software increases laboratory throughput, system uptime, and analytical reliability. With the ability to handle macro sample masses up to 3 grams (for Nitrogen/Protein analysis, independent of carbon content), rapid cycle times, and a low cost per analysis, the 928 Series is ideally suited for demanding routine and research workflows.
