TA-14 | MiniPID 2 HS Sensor Deployment Guidelines

Introduction

The MiniPID 2 HS sensor offers exceptional sensitivity with a detection range up to 3000 ppb (3 ppm), making it ideal for monitoring trace VOC levels in clean environments. However, achieving reliable performance at such low concentrations requires careful consideration of design, manufacturing, and deployment practices.

This technical article addresses the unique challenges of high-sensitivity PID deployment, including the impact of semi-volatile compounds, VOC outgassing from materials, and temperature-dependent sensor drift. It provides detailed guidance on detector housing design, pneumatic isolation, material selection, component cleaning and bake-out procedures, and proper burn-in protocols to achieve backgrounds below 200 ppb.

Essential reading for engineers and manufacturers developing ultra-sensitive VOC detection instruments for clean rooms, ambient air monitoring, and other applications requiring parts-per-billion precision.
