高纯空气是一种由高纯氧气和高纯氮气合成的混合气体, 其中的氮气、氧气比例与自然空气中氮气、氧气比例相同。高纯空气也称零点空气或零级空气。
高纯空气广泛用作气相色谱仪、气质连用仪、原子吸收仪中的助燃气体,也用于校准分析仪器的零点。
本文件规定了高纯空气的术语和定义，描述了高纯空气的制备方法、试验方法，确立了检验规则，规定了高纯空气的技术要求、标志、包装、储运及安全信息的要求。
本文件适用于由高纯氧和高纯氮为原料制备的高纯空气。

High-purity air is a mixture of high-purity oxygen and high-purity nitrogen, in which the proportion of nitrogen and oxygen is the same as that of natural air. High purity air is also called zero air or zero grade air.
High purity air is widely used as combustion gas in gas chromatographs, gas chromatographs and atomic absorption spectrometers, and is also used to calibrate the zero point of analytical instruments.
This document specifies the terms and definitions of high-purity air, describes the preparation methods and test methods of high-purity air, establishes the inspection rules, and specifies the technical requirements, marks, packaging, storage and transportation and safety information requirements of high-purity air.
This document is applicable to high-purity air prepared from high-purity oxygen and high-purity nitrogen.
