The advantages of metrological gas mixtures over other calibration methods

In the field of measuring instrument calibration, metrological gas mixtures are a reliable solution compared to other methods.

A focus within this article will be performed regarding these types of mixtures, the areas of application, and the benefits associated with their use.

Why use metrological gas mixtures for calibration

It should first be stated that metrological gas mixtures are created with the aim of providing an accurate reference point for the calibration of measuring instruments.

These are solutions composed of carefully selected gases, the concentrations of which are measured and certified, allowing different types of instrumentation to be precisely calibrated.

One example involves chemical analysis: mixtures are used to calibrate instruments such as gas chromatographs and mass spectrometers, ensuring accuracy and reliability of the analysis performed.

Scope of application of metrological gas mixtures

In addition to chemistry, metrological gas mixtures find wide use in high areas, including:

• Environmental
• Automotive
• Forensics
• Energy
• Petrochemical

Specific advantages of metrological gas mixtures

Metrological gas mixtures offer several practical advantages in addition to those already highlighted, namely:

Accuracy: Gas concentrations within the mixtures are accurately measured and certified, allowing instruments to be calibrated very precisely and reducing measurement error.

Traceability: Metrological gas mixtures are traceable to primary measurement references, ensuring that calibrations made are traceable and compliant with international standards. This is critical to the validity and comparability of the measurements made.

Wide range of gases: Mixtures can be created across a wide range of gases, allowing different applications to be covered. This offers flexibility in calibrating instruments that require calibration to specific gases or combinations of gases.

Repeatability: Metrological gas mixtures offer high reproducibility over time. Their chemical and physical properties are stable and controlled, allowing for repeatable calibrations over time.

Regulatory compliance: By using certified and traceable mixtures, compliance with required regulations and quality standards can be ensured. This is especially important in regulated industries, such as the pharmaceutical and food industries.
