Abstract
Abstract This article reviews the developmental history, fundamental technology, and general applications of time‐of‐flight mass spectrometry (TOFMS). The fundamentals of instrument operation and components are discussed. Applications in terms of gas chromatography (GC), liquid chromatography (LC), capillary electrophoresis (CE), laser desorption, multiphoton desorption, plasma desorption (PD), matrix‐assisted laser desorption, surface‐enhanced laser desorption, inductively coupled plasma (ICP), and secondary ion mass spectrometry (SIMS) are presented. A review of tandem time‐of‐flight (TOF) techniques with a focus on ion trap TOF instrumentation is provided. The purpose of this article is to provide the reader with a fundamental understanding of TOFMS principles and applications. Information is presented in a simple, straightforward, didactic fashion.

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
