Evidence Notes
Portable PID workflow for soil-vapor and remediation VOC screening
Application note based on the existing environmental-remediation scenario: ppb-level PID screening with humidity compensation and correction-factor library support VOC survey records for SVE and site-assessment work. Closure documentation depends on method requirements, target compounds, humidity conditions, and confirmatory lab or reference-method practice.

01 Measurement Principle and Limits
How the measurement is bounded
Photoionization detection uses a UV lamp to ionize VOCs with ionization potential below the lamp energy for portable screening and safety workflows.
Requires
- 10.6 eV or 11.7 eV lamp selection matched to the target compound
- Correction-factor library selection when reporting a target compound rather than isobutylene equivalent
- Humidity compensation sensor for high-moisture survey conditions
Interferents and Limits
- Water vapor can absorb UV energy and shift PID readings without humidity compensation
- High-molecular-weight or low-volatility compounds may respond slowly or require matrix review
- Halogenated or lower-ionization-potential compounds require lamp-energy and correction-factor review
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Continuous fixed-point process VOC control
- Compound-specific reporting without correction-factor review
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- portable PID detector
- 10.6 eV or 11.7 eV lamp
- humidity compensation sensor
- 100,000 data-point storage
- No external extractive conditioning system is declared for this portable SKU

07 Application Evidence
Application context from complex industrial environments.
Application Context
Remediation contractors monitoring soil-vapor-extraction (SVE) performance at 30+ landfill sites need ppb-level VOC visibility with humidity tolerance, because earlier instruments produce false positives in saturated stream that delay site-closure submissions.
Architecture Response
GS8510-PID with 1 ppb detection limit and humidity compensation supports cleanup-target confirmation across the full SVE network, so site-closure packages can be submitted on the engineering-driven timeline rather than the instrument-driven timeline.
Frequently Asked Questions
What is the difference between 10.6 eV and 11.7 eV lamps?
The 10.6 eV lamp ionizes most common VOCs (benzene, toluene, xylene, TCE). The 11.7 eV lamp also detects lower-IP compounds like formaldehyde and acetylene, but has shorter lamp life (~500 hours vs ~5000 hours).
How does the humidity compensation work?
A built-in humidity sensor measures ambient moisture content. The firmware automatically corrects the PID reading to compensate for UV absorption by water molecules, which can cause 10–30% reading errors without correction.
What is a correction factor?
Different VOC compounds have different ionization potentials and response factors. The correction factor library (400+ gases) converts the isobutylene-calibrated reading to the accurate concentration of the target compound.
Can I use it for industrial hygiene (OSHA monitoring)?
Yes, the GS8510-PID calculates TWA (8-hour) and STEL (15-minute) exposures and compares against programmable alarm setpoints — meeting OSHA and ACGIH monitoring requirements.
How often should I replace the PID lamp and sensor?
10.6 eV lamp: every 5000 hours (~2 years at 8 hr/day). Sensor electrode stack: clean monthly, replace annually. Both are user-serviceable in the field.
