This document provides a comprehensive list of standard gas mixtures, detailing their composition, reactivity, and volume. The gases are categorized as either reactive (R) or non-reactive (N/R).

Reactive gas mixtures are those that can undergo chemical reactions under certain conditions. The document lists several reactive mixtures, including:

Non-reactive gas mixtures do not readily undergo chemical reactions. Key non-reactive mixtures include:

The gas mixtures are predominantly available in two cylinder sizes: 58 litres for reactive gases and 110 litres for non-reactive gases. This standardization facilitates storage and handling.

These gas mixtures are used in various industrial applications, including calibration of gas detection equipment, research, and chemical processing. The choice between reactive and non-reactive mixtures depends on the specific requirements of the application.

This document serves as a reference for selecting appropriate gas mixtures based on reactivity and volume requirements. Proper handling and storage are essential to ensure safety and maintain the integrity of the gas mixtures.
