高純空氣是一種由高純氧氣和高純氮氣合成的混合氣體, 其中的氮氣、氧氣比例與自然空氣中氮氣、氧氣比例相同。高純空氣也稱零點空氣或零級空氣。

　　高純空氣廣泛用作氣相色譜儀、氣質連用儀、原子吸收儀中的助燃氣體,也用于校準分析儀器的零點。

　　本文件規定了高純空氣的術語和定義，描述了高純空氣的制備方法、試驗方法，確立了檢驗規則，規定了高純空氣的技術要求、標志、包裝、儲運及安全信息的要求。

　　本文件適用于由高純氧和高純氮為原料制備的高純空氣。

　　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.
