Application of differential technique in laser-induced fluorimetry /pulsed LED-fluorimetry has inherent high metrological quality. Application of differential technique in laser/LED fluorimetry fulfills the basic essential requirements of RAPs: Reliability (accuracy and high precision), Applicability (applicable to diverse sample matrices for wide applications in entire nuclear fuel cycle) and Practicability (simple, rapid and direct, easy equipments calibration, method standardization and operation, eco-friendly, cost-effective, high sample throughput, comparability, and traceability. It is a self-standardized methodology of measurement and guarantees the quality of an analytical result.
Over the years, differential technique in Laser-induced fluorimetry/pulsed LED-fluorimetry will continue to grow for the reliable measurement of uranium to fulfill the mission and mandate of uranium processing industries in entire nuclear fuel cycle for their sustainable growth worldwide.
