The LECO FP-528 is a nitrogen/protein determinator that accurately analyzes nitrogen and protein content in organic samples. It uses high-temperature combustion to convert nitrogen to nitric oxide, which is then detected by a thermal conductivity or chemiluminescence detector. The system has a rapid analysis time and an automatic sample changer that can accommodate up to 20 samples at once. It has pre-programmed methods, a user-friendly interface, and advanced safety features and software for data analysis and reporting. The FP-528 is ideal for laboratory applications in the food and agriculture industries.
