1、Designation: E1947 98 (Reapproved 2014)Standard Specification forAnalytical Data Interchange Protocol for ChromatographicData1This standard is issued under the fixed designation E1947; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision

2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 ve

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 th

4、e 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 writt

6、ational 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 spreadsheetapplications, and (5) archive analytical data,

7、or a combinationthereof. The protocol is a consistent, vendor independent dataformat that facilitates the analytical data interchange for theseactivities.1.5 The protocol consists of:1.5.1 This specification on chromatographic data, whichgives the full definitions for each one of the generic chromat

The stringshould exactly list the category values, as appropriate, as one ormore of the following “C1+C2+C3+C4+C5,” in a stringseparated by plus (+) signs.

Ex-pressed as the synthetic datetime given in the form:YYYYMMDDhhmmss6ffff.3.1.5.1 DiscussionThis is a synthesis of ISO 2014-1976(E), ISO 3307-1975 (E), and ISO 4031-1978 (E), whichcomp

19、ensates for local time variations.3.1.5.2 DiscussionThe time differential factor (ffff) ex-presses the hours and minutes between local time and theCoordinated Universal Time (UTC or Greenwich Mean Time,as disseminated by time signals), as defined in ISO 3307-1975(E). The time differential factor (ff

20、ff) is represented by afour-digit number preceded by a plus (+) or a minus (-) sign,indicating the number of hour and minutes that local timediffers from the UTC. Local times vary throughout the worldfrom UTC by as much -1200 hours (west of the GreenwichMeridian) and by as much as +1300 hours (east

21、of theGreenwich Meridian). When the time differential factor equalszero, this indicates a zero hour, zero minute, and zero seconddifference from Greenwich Mean Time.3.1.5.3 DiscussionAn example of a value for this dateelement would be: 1991,08,01,12:30:23-0500 or19910801123023-0500. In human terms t

22、his is 12:30 PM onAugust 1, 1991 in New York City. Note that the -0500 hours is5 full hours time behind Greenwich Mean Time. The ISOstandards permit the use of separators as shown, if they arerequired to facilitate human understanding. However, separa-tors are not required and consequently shall not

23、 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, because this eliminates problems with thedifferent month abbreviations used in different human lan-guages.3.1.6 dataset-originname of the organizatio
