Role of Energy Dispersive XRF (ED-XRF) in Development of Rare Earth Element-2, International Certified Standard Reference Material: Ambiguities and Constraints
Bibliographic record
Abstract
Abstract The REE-2 is a carbonatite sample with rare earth elements provided from a Canadian mining company and distributed by Canadian Certified Reference Materials (CCRM), Canada. The reference material was provided to participate in the testing process (round-robin) and CSIR-NGRI, Hyderabad, state of the art analytical technique Energy Dispersive X-ray fluorescence (EDXRF) also contributed to the development of this (REE −2) reference material. In this paper, the efficacy of analytical protocol developed and comparing the results with twenty one industrial, commercial and government laboratories across globe in an inter-laboratory measurement program are presented. The CSIR-NGRI, EDXRF analytical facility contribution and steps to overcome during REE-2 development are briefly discussed. This contribution is to highlight the international analytical standards and protocols maintained at EDXRF laboratory vis-à-vis international laboratories.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
