Certified metrological gas mixtures: how to reduce hidden costs in process management

Hidden costs in analytical and production processes are a critical yet often underestimated factor. 

These indirect expenses, difficult to anticipate during planning, typically emerge as the result of issues distributed across the process chain, with effects that become evident in the medium to long term.

The use of certified metrological gas mixtures significantly reduces such inefficiencies, supporting operational stability and safeguarding data integrity.

Main sources of hidden costs in reference gas-based processes

Hidden costs arise at several critical stages of analytical and production workflows. The most common include:

• Use of non-certified mixtures with nominal values that are unstable or non-compliant.
• Repeated analyses due to non-repeatable or out-of-specification results.
• Temporary deviations from internal protocols caused by inadequate or poorly stored mixtures.
• Reduced overall reliability of measurement systems and diminished final product quality.

In all these cases, the absence of metrological traceability and formal uncertainty statements increases risk and reduces process efficiency.

Distinctive features of certified metrological mixtures

Certified metrological gas mixtures are produced in compliance with rigorous international standards, ensuring measurement traceability and reliability of declared values in line with ISO 17025 and ISO 17034.

Key features include:

• Full traceability of the concentration of each component.
• Formal declaration of measurement uncertainty.
• Documented long-term validity, with references to internationally recognized standards.

These elements enable safe integration into measurement protocols, reducing variability and improving consistency across analytical sessions. 

Economic impact of certified mixtures in process management 

Systematic use of certified metrological gas mixtures contributes to lower indirect costs in several ways:

• More reliable testing: certified mixtures prevent rework caused by inconsistent or out-of-spec results.
• Greater efficiency in quality control: less time is needed to validate results, increasing laboratory productivity.
• Reduced downtime: precise alarms and accurate calibrations prevent anomalies and critical drifts.

In short, adopting certified gas mixtures is a strategic investment, delivering benefits for operational continuity, product quality, and overall process efficiency.
