Viscometric Constants for Sodium Polystyrene Sulfonate Standards in Solvents of 0.1 M CH<sub>3</sub>COOH/0.2 M NaCl and 0.2 M CH<sub>3</sub>COOH/0.1 M CH<sub>3</sub>COONa at 25.0 °C
Bibliographic record
Abstract
The viscometric or Mark−Houwink constants K and a for sodium polystyrene sulfonate (NaPSS) standards in two different aqueous solvents (0.1 M CH 3 COOH/0.2 M NaCl and 0.2 M CH 3 COOH/0.1 M CH 3 COONa) were determined at 25.0 °C using a Ubbelohde viscometer. They are 3.288 × 10 - 3 mL·g - 1 and 1.908 × 10 - 3 mL·g - 1 for K and 0.788 and 0.851 for a for the above two solvent systems, respectively. These constants were then used for establishing the universal calibration relationship for a size exclusion chromatography column using the above two aqueous solvents as the mobile phase.

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.
