1.1 本规范涵盖了色谱数据表示的标准格式和实现仪器数据系统之间色谱数据传输的软件工具。本规范提供了旨在使分析仪器用户受益并提高实验室生产率和效率的协议。 1.2 本规范中的协议为原始数据文件或结果文件的创建提供了标准化格式。此标准格式具有扩展名“.cdf”（源自NetCDF）。文件的内容包括典型的标题信息，如仪器、色谱柱、检测器和操作员描述，然后是原始数据或处理数据，或两者兼而有之。一旦数据被写入或转换为该协议，它们就可以被支持该协议的软件包读取和处理。 1.3 本规范中用于协议的软件传输工具是NetCDF，由Unidata计划开发，由国家科学基金会大气科学部资助。 2. 1.4 本规范中的协议旨在( 1. )在各个供应商的仪器系统之间传输数据( 2. )提供LIMS通信( 3. )将数据链接到文档处理应用程序( 4. )将数据链接到电子表格应用程序，以及( 5. )存档分析数据或其组合。该协议是一种一致的、独立于供应商的数据格式，有助于这些活动的分析数据交换。 1.5 协议包括: 1.5.1 本色谱数据规范给出了协议实施中使用的每个通用色谱数据元素的完整定义。 它定义了分析信息类别，这是对分析数据元素进行排序以使其更易于标准化的便捷方式。 1.5.2 指导 1948年 该文件详细介绍了如何使用公共域NetCDF数据交换系统实现协议内容。它包括使用NetCDF的简要介绍。它适用于软件实现者，而不是那些想要理解色谱数据集中数据定义的人。 1.5.3 NetCDF用户指南。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers a standardized format for chromatographic data representation and a software vehicle to effect the transfer of chromatographic data between instrument data systems. This specification provides protocol designed to benefit users of analytical instruments and increase laboratory productivity and efficiency. 1.2 The protocol in this specification provides a standardized format for the creation of raw data files or results files. This standard format has the extension “.cdf” (derived from NetCDF). The contents of the file include typical header information like instrument, column, detector, and operator description followed by raw or processed data, or both. Once data have been written or converted to this protocol, they can be read and processed by software packages that support the protocol. 1.3 The software transfer vehicle used for the protocol in this specification is NetCDF, which was developed by the Unidata Program and is funded by the Division of Atmospheric Sciences of the National Science Foundation. 2 1.4 The protocol in this specification is intended to ( 1 ) transfer data between various vendors' instrument systems, ( 2 ) provide LIMS communications, ( 3 ) link data to document processing applications, ( 4 ) link data to spreadsheet applications, and ( 5 ) archive analytical data, or a combination thereof. The protocol is a consistent, vendor independent data format that facilitates the analytical data interchange for these activities. 1.5 The protocol consists of: 1.5.1 This specification on chromatographic data, which gives the full definitions for each one of the generic chromatographic data elements used in implementation of the protocol. It defines the analytical information categories, which are a convenient way for sorting analytical data elements to make them easier to standardize. 1.5.2 Guide E1948 on chromatographic data, which gives the full details on how to implement the content of the protocol using the public-domain NetCDF data interchange system. It includes a brief introduction to using NetCDF. It is intended for software implementors, not those wanting to understand the definitions of data in a chromatographic dataset. 1.5.3 NetCDF User’s Guide. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
