Improvement in the determination of Fe and Si and their isotope ratios by ICP-MS. Part I. Desolvating nebulizer
Bibliographic record
Abstract
L'etude de l'influence d'un systeme de nebulisation par desolvation sur les nombreuses interferences polyatomiques associees a l'analyse isotopique de Si + et Fe + (CO + , COH + , NO + , NOH + , O 2 +, ArH + , CO 2 +, ArN + , ArNH + , ArO + , ArOH + , et Ar 2 H + ) fut menee. Un systeme de nebulisation conventionel ainsi que le systeme de nebulisation par desolvation furent compares. L'utilisation du systeme de nebulisation par desolvation ameliore a la fois les limites de detection et l'exactitude des ratios isotopiques pour le Fe et le Si. Une amelioration des limites de detection d'un factor de 160 et 15 pour le fer et le silicium, respectivement, fut observee. Les quantites necessaires pour mesurer avec exactitude les differents ratios isotopiques a l'aide d'un Q-ICP-MS couple au systeme de nebulisation par desolvation de chacun de ces elements dans les echantillons ont ete determinees.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
