Laser pyrolysis gas chromatography system using a Q-switched Nd : YAP laser.
Bibliographic record
Abstract
A pyrolysis gas chromatograph system using a pulsed Nd:YAP laser as a fragmentation source was constructed, which allowed for the direct analysis of solid samples. Several solid samples, such as ceramics (BN), coal, and polystyrene, were analyzed to test the performance of the system. The obtained chromatograms showed good reproducibility, and the relative standard deviations of the peak intensity, the FWHM, and the retention time were 1.4%, 2.2%, and 0.5%, respectively. In chromatograms obtained from polystyrene, the characteristic component peaks of benzene, toluene, and styrene monomer were detected. Moreover, a moderate defocusing of laser radiation brought about an increase in the signal intensity. The results showed that the present laser pyrolysis gas chromatograph is applicable to the analysis of solid samples.

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.
