Utility description: Xe Recovery Efficiency & Recycling QC

Xe Recovery Efficiency & Recycling QC — Xe Recovery Efficiency and Recycling Quality Control

ℹ️  Utility evaluates economics and quality of gas return process:
    • Volume and mass collection efficiency
    • Gas purity after cleaning
    • Financial savings per session

⚠️  CRITICAL: Loss of enriched xenon is direct financial loss!
    Efficient recycling reduces study cost by multiples.

Usage:
  XeRecoveryEfficiencyAndRecyclingQC.exe                            → demo mode (console output)
  XeRecoveryEfficiencyAndRecyclingQC.exe input.csv output.json      → evaluate your data

Input format:
BatchNumber,ProductName,Admin_Vol_L,Recovered_Raw_L,Recycled_Pure_L,Init_Purity_Percent,Rec_Purity_Percent,Cost_Per_L,Min_Eff_Percent,Min_Pur_Percent

Example:
  REC-QC-2026-001,HP-Xe-129,1.0,0.95,0.90,90,89.5,2000,85,90

— WHY IS THIS NEEDED?
Recycling is critical for economic sustainability of HP-MRI centers:
• Enriched Xe-129 costs thousands of dollars per liter
• Patient exhales >90% of administered gas
• Recovery systems collect, clean from CO2/moisture and return gas to cycle
• Utility helps assess system efficiency and money savings
• Purity control after cleaning guarantees gas suitability for re-polarization

⚠️  CRITICAL:
• Volume collection efficiency ≥85%
• Mass efficiency (accounting for purity) ≥85%
• Purity after recycling ≥90% (for reuse possibility)
• Minimization of financial losses per session

Key features:
• Real mass efficiency calculation (not just volume)
• Financial benefit assessment from recycling
• Cleaning quality control (impurity removal)
• Leak and inefficient cleaning stage detection

Critical parameters:
• Volume Recovery: ≥85%
• Mass Recovery: ≥85%
• Recycled Purity: ≥90%
• Loss Cost: < $50/session

💡 Usage tips:
1. Regularly replace cleaning filters (CO2, H2O) to maintain purity
2. Check tightness of all recovery circuit connections
3. Use data to calculate ROI of recovery equipment
4. Compare efficiency of different compressor modes
5. Maintain cumulative savings log for budget justification

⚠️ Note: Unlike standard waste, here "trash" is gold. The utility turns technical gas collection parameters into clear financial metrics, showing real value of every liter of recovered xenon.

QA/QC and change control

Do not change column names without updating the validator, documentation and test set.

Before production use, verify local limits and execute IQ/OQ/PQ or equivalent CSA.
Changes affecting patient safety, dosimetry, gas composition, polarization or equipment require documented impact assessment.
