1、Designation: E 1947 98 (Reapproved 2004)Standard Specification forAnalytical Data Interchange Protocol for ChromatographicData1This standard is issued under the fixed designation E 1947; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisi

2、on, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers a standardized format forchromatographic data representation and a software

3、 vehicle toeffect the transfer of chromatographic data between instrumentdata systems. This specification provides protocol designed tobenefit users of analytical instruments and increase laboratoryproductivity and efficiency.1.2 The protocol in this specification provides a standard-ized format for

4、 the creation of raw data files or results files.This standard format has the extension “.cdf” (derived fromNetCDF). The contents of the file include typical headerinformation like instrument, column, detector, and operatordescription followed by raw or processed data, or both. Oncedata have been wr

5、itten or converted to this protocol, they canbe read and processed by software packages that support theprotocol.1.3 The software transfer vehicle used for the protocol inthis specification is NetCDF, which was developed by theUnidata Program and is funded by the Division ofAtmosphericSciences of th

6、e National Science Foundation.21.4 The protocol in this specification is intended to (1)transfer data between various vendors instrument systems, (2)provide LIMS communications, (3) link data to documentprocessing applications, (4) link data to spreadsheet applica-tions, and ( 5) archive analytical

7、data, or a combination thereof.The protocol is a consistent, vendor independent data formatthat facilitates the analytical data interchange for these activi-ties.1.5 The protocol consists of:1.5.1 This specification on chromatographic data, whichgives the full definitions for each one of the generic

8、 chromato-graphic data elements used in implementation of the protocol.It defines the analytical information categories, which are aconvenient way for sorting analytical data elements to makethem easier to standardize.1.5.2 Guide E 1948 on chromatographic data, which givesthe full details on how to

9、implement the content of the protocolusing the public-domain NetCDF data interchange system. Itincludes a brief introduction to using NetCDF. It is intended forsoftware implementors, not those wanting to understand thedefinitions of data in a chromatographic dataset.1.5.3 NetCDF Users Guide.2. Refer

The stringshould exactly list the category values, as appropria

19、heCoordinated Universal Time (UTC or Greenwich Mean Time,as disseminated by time signals), as defined in ISO 3307. Thetime differential factor (ffff) is represented by a four-digitnumber preceded by a plus (+) or a minus (-) sign, indicatingthe number of hour and minutes that local time differs from

20、 theUTC. Local times vary throughout the world from UTC by asmuch -1200 hours (west of the Greenwich Meridian) and by asmuch as +1300 hours (east of the Greenwich Meridian). Whenthe time differential factor equals zero, this indicates a zerohour, zero minute, and zero second difference from Greenwic

Note that the -0500 hours is5 full hours time behind Greenwich Mean Time. The ISOstandards permit the u

22、se of separators as shown, if they arerequired to facilitate human understanding. However, separa-tors are not required and consequently shall not be used toseparate date and time for interchange among data processingsystems.3.1.5.4 DiscussionThe numerical value for the month ofthe year is used, bec

Themeaning of this category assignment is explained in Section 5.NOTE 2T

32、he Required column indicates whether a data element isrequired, and if required, for which categories. For example, M1234indicates that that particular data element is required for any dataset thatincludes information from Category 1, 2, 3, or 4. M4 indicates that a dataelement is only required for

33、Category 4 datasets.NOTE 3Unless otherwise specified, data elements are generally re-corded to be their actual test values, instead of the nominal values thatwere used at the initiation of a test.Data Element Name Datatype Category Requireddataset-completeness string C1 M12345protocol-template-revis

This information makes the datasetself-referenced for easier viewing and provides internal docu-mentation for GLP-compliant systems.3.1.18.1 DiscussionThis data e

39、lement should include thecomplete filename, including node name of the computersystem. For UNIX this should include the full path name. ForVAX/VMS this should include the node-name, device-name,directory-name, and file-name. The version number of the file(if applicable) should also be included. For

40、personal computernetworks this needs to be the server name and directory path.3.1.18.2 DiscussionIf the source file was a library file,this data element should contain the library name and serialnumber of the dataset.3.2 Definitions for Sample-Description Information ClassThis information class is c

41、omprised of nominal informationabout the sample. This includes the sample preparation proce-dure description used before the test(s). In the future this classwill also need to contain much more chemical method andgood laboratory practice information. See Table 2.3.2.1 sample-amountsample amount used
