PFAScreen is an open-source Python based non-target screening software tool to prioritize potential PFAS features in raw data from LC- or GC-HRMS measurements with a simple GUI. It uses several prioritization techniques such as the MD/C-m/C approach, KMD analysis, and fragment mass differences and diagnostic fragments in the MS2 data.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 15 stars here means stars gained during the window, not the repo's star count.
