Evidence Notes
Multi-component FTIR architecture for refinery and petrochemical gas streams
The v1 petrochemical scenario uses one FTIR platform for several refinery gas components that would otherwise require separate analyzer paths. The engineering case is channel consolidation, shared sample handling, and model-based interference review rather than a promised reduction in footprint or calibration effort.

01 Measurement Principle and Limits
How the measurement is bounded
FTIR captures a full infrared spectrum and uses chemometric models to resolve multiple configured gas components from overlapping absorption bands.
Rejects
- Gas components not covered by the configured chemometric library
- Condensing sample without heated cell or conditioning review
- Field component changes without channel validation
Requires
- Component list and chemometric model selected for the target gas matrix
- Heated cell or sample conditioning selected according to moisture and condensation risk
- Vibration-isolated optics and stable purge / sample handling for low-ppm applications
- Channel-by-channel calibration and interference review before adding field components
Interferents and Limits
- H2O has broad infrared absorption and can affect FTIR channels if the model and conditioning are not matched to the matrix
- CO2, hydrocarbons, NH3, and H2O can share spectral regions and require chemometric deconvolution review
- Low-ppm duty may require N2 purge and tighter sample handling
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Condensing sample without heated cell or conditioning review
- Unvalidated field addition of gas components
- Low-ppm duty without purge and matrix review
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- FTIR heated sample cell
- chemometric model library
- GS-SCS-800 heated sampling system or GS-SCS-600 cool-dry system as selected by moisture duty
- optional N2 purge for low-ppm applications
- No universal sample-conditioning path is declared; sample handling depends on moisture and target components

06 Maintenance & Spares site-specific
Tasks, consumables, and access items are shown only when structured maintenance data is available.
- Verify the configured component list and chemometric model after process-matrix changes
- Inspect heated cell and optical path according to sample moisture and particulate loading
- Review N2 purge supply for low-ppm applications
- Confirm OPC-UA / MQTT / Modbus TCP data mapping after channel changes
- Optical-path service parts
- sample-line filter or conditioning parts
- calibration gases per configured channel
07 Application Evidence
Application context from complex industrial environments.
Application Context
Ethylene crackers needing simultaneous monitoring of 8 gas components (CO, CO₂, CH₄, C₂H₄, C₂H₆, C₃H₈, H₂O, NH₃) traditionally instrument 8 separate analyzers, consuming rack space and creating 8 independent calibration cycles.
Architecture Response
A single GS8600-MG replaces all 8 analyzers in one 6U rack space, and AI drift compensation supports stable calibration over extended intervals, so cracker-side instrumentation footprint and calibration overhead both shrink to a single platform.
Frequently Asked Questions
How does FTIR measure multiple gases simultaneously?
FTIR captures the complete infrared absorption spectrum in a single scan. Mathematical deconvolution (chemometric modeling) resolves overlapping absorption bands to quantify each component independently — even when spectral features overlap.
What is AI drift compensation?
The onboard AI model continuously analyzes measurement patterns and environmental conditions to predict and correct for long-term optical drift. This extends the interval between manual recalibrations from weeks to 6+ months.
Can I add or change measured components in the field?
Yes, the GS8600-MG is software-configurable. New gas components can be added by loading the appropriate chemometric model from the configured library — no hardware changes required.
What is the cross-interference correction?
When two gases absorb at similar wavelengths, the AI-powered cross-interference matrix automatically compensates. The self-learning algorithm improves correction accuracy over time as it accumulates operational data.
Does it support Industry 4.0 integration?
Yes, native OPC-UA (OPC Foundation certified), MQTT, and Modbus TCP. Direct integration with plant historians, SCADA, MES, and digital twin platforms without middleware.
What sample conditioning is required?
For process gas, use the GS-SCS-600 Cool-Dry System or GS-SCS-800 Heated System depending on moisture content. The optional heated 180 °C sample cell allows hot-wet measurement without sample conditioning for some applications.
