The Development of Volatile Organic Compounds(VOCs) in Nitrogen Gas Standard Material
Bibliographic record
Abstract
The article described the development of volatile organic compounds(VOCs) gas standard material used for indoor air quality evaluation.Namely,benzene,toluene,ethylbenzene,p-xylene,m-xylene,o-xylene,styrene,ethyl acetate,butyl acetate and undecan in nitrogen gas standard material,prepared by weighing method,then analyzed by gas chromatography to confirm the uniformity and stability.Measured by the National Institute of Metrology of China(NIM China),the data of the samples conforms with similar standard gases from other country.It has been approved by the state in file GBW(E) 060756 that the gas material can be used as second level standard material.The standard value can be as low as 0.5 ×10-6 mol/mol.The relative uncertainty is 6%(k= 2).

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.
