Engineering for Analytical Integrity
Reliable process analysis depends on far more than the analyser itself. Sample extraction, transport, conditioning, pressure and temperature control, calibration and system integration all influence whether the reported value truly represents the process. Combining process physics, chemistry, electrical and instrumentation engineering, we build complete systems that deliver dependable process measurement rapidly.
Reliable analysis begins with extracting a sample that accurately represents the process stream. Poor sample location or extraction design can introduce bias before the sample ever reaches the analyser.
QMI considers:
- Sampling location
- Probe configuration
- Process velocity
- Liquid entrainment
- Particulate loading
- Sample compatibility
Probe, quill and extraction arrangements are engineered around the process conditions, analyser requirements and expected contaminants to maintain representative sampling.
Changes in pressure and temperature can alter the physical state or composition of a sample, particularly where condensation, vaporisation or adsorption may occur.
QMI considers:
- Process dew point
- Pressure reduction
- Sample temperature
- Heat tracing
- Condensation risk
- Vaporisation requirements
Where required, heated probes, regulators, sample lines and conditioned enclosures are used to maintain the sample in the correct phase throughout the measurement chain.
Sample pressure, flow and system volume determine how quickly and consistently process changes reach the analyser.
QMI considers:
- Pressure reduction
- Sample flow
- Transport volume
- Fast-loop design
- Bypass flow
- Response time
Tubing sizes, regulators, flow devices and bypass arrangements are selected to achieve the required analyser conditions while controlling transport delay and pressure-drop effects.
The measurement principle must be appropriate for both the target component and the wider process composition. Cross-interferences and changing background gases can significantly affect analytical performance.
QMI considers:
- Measurement range
- Detection limits
- Gas composition
- Cross-interferences
- Analyser technology
- Materials compatibility
QMI evaluates the process chemistry alongside analyser performance to select technologies capable of delivering stable and selective measurement under real operating conditions.
Online analysers require a practical means of checking measurement performance throughout their operating life.
QMI considers:
- Calibration gases
- Zero validation
- Span validation
- Stream switching
- Calibration frequency
- Reference standards
Calibration and validation facilities are integrated into the system so analyser performance can be verified without compromising normal operation or sample-system integrity.
A reliable analyser package must remain practical to operate, inspect, calibrate and maintain long after commissioning.
QMI considers:
- Component access
- Isolation points
- Diagnostic visibility
- Consumable replacement
- Spare parts availability
- Spare part COSTS
- Future upgrades
Systems are engineered for maintainability from the outset, with QMI supporting commissioning, troubleshooting, calibration, servicing and future system modifications throughout the equipment lifecycle.
