Calibration of gas analyzers is the process of verifying the accuracy of these devices. The purpose of calibration is to ensure the reliability of measurements of chemical substance concentrations in the air. We use toxic gas analyzers to monitor the presence of substances that can be harmful to human health, even in small amounts. These substances include compounds such as carbon monoxide (CO), nitrogen oxides (NOx), nitric oxide (NO), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and carbon dioxide (CO₂). Of course, the list of harmful substances is not limited to those mentioned. There are many other substances that may be toxic or irritating to the respiratory system.
Why are devices calibrated?
Proces wzorcowania analizatorów gazów toksycznych ma kluczowe znaczenie z kilku powodów:
- The process of calibrating toxic gas analyzers is crucial for several reasons:
The accuracy of toxic gas concentration measurements is vital for ensuring the safety of workers, residents, and environmental protection. Calibration serves this purpose—it is a set of activities aimed at verifying the metrological properties of a given instrument. Calibration involves comparing the readings of the tested device under defined conditions (at specific calibration points) with the readings of an appropriate reference standard. - Compliance with regulations:
Many air quality regulations define limits for toxic gas emissions that must be respected. The results of gas analyzer calibration have a significant impact on informed decision-making (e.g., by taking into account measurement error in the final results). - Effective response in crisis situations:
Accidents or failures are often accompanied by the release of toxic gases. Measuring their concentration is essential for effective crisis management and for making decisions regarding emergency response.
Who uses calibration services?
Individuals and institutions that use toxic gas analyzers and require their calibration may include:
- Industry:
Manufacturing plants, refineries, power plants, chemical plants, and other industrial institutions that use, store, or generate toxic gases as part of their production processes. - Emergency services:
Fire brigades, medical services, and other rescue services use toxic gas analyzers in the event of accidents, industrial failures, or other crisis situations. - Research institutions:
The main users of calibration services are research laboratories involved in studies on air quality and public health. Organizations studying the environmental impact of toxic gas emissions also rely on toxic gas analyzers. Another group consists of academic and teaching units engaged in scientific research and environmental monitoring.
Calibration of toxic gas analyzers is therefore essential to ensure safety and compliance with regulatory requirements.
Who performs calibration services?
Calibration of gas analyzers is carried out by specialists with the appropriate authorizations, experience, and technical expertise. Key aspects regarding those who perform toxic gas analyzer calibration include:
- Competence and accreditation:
The competence and authorization of personnel performing calibrations are confirmed through periodic audits conducted by PCA (Polish Centre for Accreditation). - Professional experience:
It is important that the person performing the calibration of toxic gas analyzers has relevant professional experience in calibration, operation, and maintenance of such devices. This experience enables effective troubleshooting, diagnostics, and accurate calibration. - Technical knowledge:
Specialists performing toxic gas analyzer calibration must have in-depth technical knowledge of the principles of these devices, measurement processes, types of toxic gases, and calibration and diagnostic methods. This knowledge allows them to effectively identify potential errors and risks associated with the instruments. - Quality control measures:
Individuals performing calibration must apply proper quality control procedures to ensure accuracy and reliability of measurements. These procedures include regular verification of reference equipment, the use of appropriate standards and calibration methods, and proper documentation of all performed operations.
It is essential that those performing toxic gas analyzer calibration are properly trained. They should have relevant experience and certifications that guarantee the high quality and reliability of measurements. Furthermore, using accredited laboratories or companies specializing in calibration services provides assurance regarding the quality of the work performed.
One such facility is our calibration laboratory, accredited under number AP 002.
