Project background
The original site reports acceptance of Nayur's independently developed NaU-E800 polarized secondary-target energy-dispersive XRF spectrometer. The project was a subtask under a national Eleventh Five-Year Plan science and technology program and reflects the company's work on polarized spectrometry.
Performance reported in the original account
The report states that relevant experts confirmed a 2–8-fold improvement in sensitivity and analytical precision for trace toxic and hazardous substances compared with XRF energy-dispersive instruments available at the time. It describes measurement of toxic or hazardous elements or metals at ≥0.5 ppm in oils, waste liquids or plastics.
These are historical project statements. The source does not supply full details of comparator instruments, sample conditions or test reports; they are not general guarantees for current products. One passage uses “NaU-800”; this page follows the project name NaU-E800.
Development organization
The company introduced procedures for new product development and incentives to define objectives, scope and responsibilities. Development could be led by the design department, jointly by sales and design, across departments, or with external collaborators.
Product record for 2019
The original account states that, by its 2019 profile, Nayur had developed nine XRF products in five series. It grouped them into general testing, precision laboratory work, dedicated systems for large corporate groups, and dedicated government applications. These figures retain their historical context and do not describe the current product count.
