The GB/T 41942-2022 standard stipulates the use of micro-Dumas combustion method for the determination of nitrogen content for natural raw rubber and natural latex. The standard specifies the experimental equipment, Sample Handling process, and the nitrogen element is converted through combustion samples, and then the content is accurately determined. With this standard, it can accurately grasp the nitrogen content of natural raw rubber and natural latex, provide key data for product mass evaluation and performance control, and help optimize the production process and ensure product quality in natural rubber production, processing and related Applications.
