Analytical Audits
When the data driving your process has to be data you can trust — and your operators, regulators, and bottom line all depend on the readings — regular audits are the only way to know your analyzers are still measuring true. Analytical audits from TriNova evaluate every sensor, transmitter, sample system, and signal path across your analytical loop, confirming accuracy, calibration status, and measurement integrity.
How TriNova conducts an Analytical Audit
During the audit, TriNova specialists conduct a structured review of your full analytical loop — analyzers, sensors, transmitters, sample conditioning systems, and the wiring and signal paths that carry readings to your control system. The team evaluates device condition, calibration status, sample system integrity, signal output, and system documentation against your facility's measurement and compliance requirements.
The result is a clear assessment of analyzer condition along with a prioritized set of recommendations you can act on immediately or plan for over time.
- Inspection of analyzers, sensors, transmitters, and sample conditioning systems
- Device condition and calibration status verification
- Functional testing of analyzer response and signal output
- Sample system, field wiring, and signal path review
- System documentation and configuration alignment with measurement requirements
- Prioritized recommendations to improve accuracy, reliability, and lab correlation
The Outcome
What an Analytical Audit delivers
Measurement accuracy verified
Know that every analyzer, sensor, and sample system is producing readings you can trust. The audit identifies the drift, fouling, and configuration gaps that quietly compromise your process data.
A performance baseline
Establish a clear baseline for long-term maintenance and calibration planning. Understand the true condition of your analytical systems and where measurement risks are concentrated.
Answers to chronic drift
Troubleshoot persistent analyzer problems — readings that won't hold calibration, lab correlation that keeps slipping, signal noise that won't go away — by identifying root causes, not just symptoms.
A foundation for long-term planning
Use audit findings to prepare for analyzer upgrades, justify capital investment, and build a long-term strategy for managing your measurement infrastructure.
When to schedule an audit
Common reasons facilities request an Analytical Audit
- Preparing for regulatory, environmental, or internal compliance review
- Verifying analyzer accuracy after process changes, expansions, or new product runs
- Troubleshooting persistent drift, signal noise, or lab-to-analyzer discrepancies
- Establishing a baseline for long-term calibration and maintenance planning
- Evaluating aging analytical infrastructure ahead of capital planning
Analytical Audit FAQs
How long does an analytical audit take? Field work typically takes one to several days depending on facility size and the number of analyzers covered. The written report and prioritized recommendations are generally delivered within two to three weeks of the field visit.
Does the audit disrupt operations or require taking analyzers offline? Most of the audit is conducted with analyzers in service. Some functional testing — calibration verification, sample system checks, or signal validation — may require coordinating with your operations team or briefly switching to backup sampling. We work around your operating windows.
What do we receive at the end? A detailed written assessment that includes analyzer-by-analyzer findings, sample system and wiring evaluation, calibration status, and a prioritized list of recommendations. The report is structured to support both immediate corrective action and long-term measurement system management.
