What is EN ISO 6143:2017?

EN ISO 6143:2017 is a professional technical standard that specifies the requirements and guidelines for using headspace gas chromatography (HS-GC) to determine the purity of gases. This standard has been developed by the European Committee for Standardization (CEN) and is widely recognized and accepted in the field of analytical chemistry.

Purpose of EN ISO 6143:2017

The main purpose of EN ISO 6143:2017 is to provide a standardized method for accurately measuring the impurities in various gases. By using HS-GC, the concentration of impurities such as moisture, volatile organic compounds, permanent gases, and hydrocarbons can be determined with high precision and reliability. The results obtained through this method are essential in ensuring the quality and safety of gases used in various industries and applications.

Key Features and Requirements

EN ISO 6143:2017 outlines the key features and requirements for performing HS-GC analysis. It covers aspects such as sampling methods, instrument calibration, analytical performance, data analysis, and reporting. One of the critical features highlighted in the standard is the preparation of gas samples utilizing headspace techniques, which involves removing the gas from the sample matrix while preserving its integrity.

Furthermore, the standard emphasizes the importance of accurate calibration of instruments and includes guidelines on how to perform calibration procedures effectively. It also provides recommendations on analyzing the data obtained from GC analysis and reporting the results in a clear and comprehensive manner.

Benefits and Applications

The adoption of EN ISO 6143:2017 brings several benefits to laboratories and organizations involved in gas analysis. Firstly, it ensures the accuracy and reliability of gas purity measurements, which is crucial for meeting regulatory requirements and quality control standards.

Additionally, this standard allows for better comparability of results obtained from different laboratories, facilitating harmonization and consistency in gas analysis methods worldwide. It also enables manufacturers to verify the purity of gases used in product development and production processes, ensuring the quality and performance of their products.
