# ec-sample-tracker-1.0.0 — Sample Tracker for Electrochemistry Labs Track physical samples from synthesis through every characterization result. Connect samples to their storage locations, synthesis records, and all associated data files (LSV/CV/EIS/XRD/SEM/TEM etc.). ## Usage ```bash ec-sample-tracker <command> [options] ``` ## Commands - `add` — Register a new sample - `list` — List samples with filters - `status` — Show sample status overview - `link` — Attach data files or notes to a sample - `search` — Search samples by name, tag, synthesis date, or property - `log` — Log an experimental event (measurement, storage move, aging) - `export` — Export sample records as CSV/JSON/Markdown - `import` — Bulk import from CSV - `dashboard` — Visual dashboard of sample inventory and status ## Sample Record Schema ``` sample_id — Auto-generated (e.g. CAT-2026-0042) name — Sample name/label synthesis_date — YYYY-MM-DD synthesis_method — hydrothermal / electrodeposition / impregnation / sol-gel / thermal decomposition / commercial precursors — Comma-separated list substrate — GC / Ti foil / Ni foam / FTO / ITO / Carbon paper / None catalyst_load — mg/cm² (if applicable) target_reaction — OER / HER / ORR / CO2RR / other tags — Comma-separated tags storage_location — fridge-4 / rack-A2 / desiccator-2 / given-out owner — Name notes — Free-text notes status — active / degraded / given-out / disposed / lost ``` ## Link Types - `ec` — LSV/CV/EIS/CP/CA files - `xrd` — XRD data - `sem` / `tem` — Electron microscopy - `raman` — Raman spectra - `xps` — XPS data - `photo` — Sample photos - `note` — Free-text notes - `protocol` — Synthesis protocol PDF ## Configuration (config.yaml) ```yaml lab_name: "Electrochemistry Lab" id_prefix: "CAT" next_id: 1 storage_locations: - fridge-4 - rack-A2 - rack-B1 - desiccator-2 - drawer-3 - given-out default_owner: "xray" db_file: "samples.db" data_root: "/home/xray/data" ``` ## Dashboard Generates a 4-panel PNG dashboard: 1. Sample count by status (pie chart) 2. Samples by reaction type (bar chart) 3. Storage location distribution (bar chart) 4. Recent activity log (text table) ## Examples ```bash # Add a new sample ec-sample-tracker add --name "NiFe-LDH/CF-2026-042" \ --method hydrothermal --precursors "Ni(NO3)2,Fe(NO3)3" \ --substrate "Ni foam" --load 2.1 --reaction OER \ --tags "NiFe-LDH,hydrothermal,batch-42" \ --storage fridge-4 --notes "Synthesized for OER stability test" # Link characterization data ec-sample-tracker link CAT-2026-0042 --type ec --file ~/data/oer_lsv_042.csv ec-sample-tracker link CAT-2026-0042 --type xrd --file ~/data/xrd_042.asc # Search samples ec-sample-tracker search --tag NiFe-LDH --reaction OER ec-sample-tracker search --synth-date-after 2026-03-01 # List all active samples ec-sample-tracker list --status active # Log an experimental event ec-sample-tracker log CAT-2026-0042 --event "LSV cycling started" \ --note "100 cycles in 1M KOH, 10 mA/cm²" # Export all samples ec-sample-tracker export --format markdown --output samples-report.md # Generate dashboard ec-sample-tracker dashboard --output sample-dashboard.png ``` ## Database Uses SQLite (`samples.db`) with tables: - `samples` — Core sample records - `links` — File/note attachments - `events` — Timestamped experimental events - `measurements` — Quantitative measurement results (overpotential, Tafel, ECSA, etc.) ## Output Files - `samples.db` — SQLite database - `samples.csv` — Full export - `sample-dashboard.png` — Visual dashboard (300 DPI) - `sample-YYYY-MM-DD.md` — Markdown report ## Use Cases - Track which samples have LSV/CV/EIS data collected - Find all samples from a specific synthesis batch or precursor combination - Log degradation events and link to characterization - Generate sample inventory for lab audits or paper supplementary - Connect synthesis records to performance metrics
