Abstract
Recent advances in quadrupole TOF (Q-TOF) MS have some bioanalytical scientists referring to a 'paradigm shift' in their field. They are speaking of a potential move away from workflows based upon triple-quadrupole MS. Gone would be the optimizing of numerous parameters in selected-reaction monitoring (SRM) experiments, replaced with more generic workflows provided by Q-TOF instruments with high data acquisition rates, excellent mass accuracy (≤5 ppm) and high resolving power (≥30,000). Such a move could pay real dividends for high-throughput workflows, especially in drug metabolism and pharmacokinetics analyses where quantitation and qualification studies could actually be merged. But, are modern Q-TOF-MS instruments, touted as high-resolution MS, ready for this? If not, how close is it? This article will examine these questions by reviewing recent advances in Q-TOF technology and some fascinating orthogonal technology (such as ion mobility) that modern Q-TOFs employ for even greater analytical power.

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 it
