    1、Designation: E 2077 00 (Reapproved 2005)Standard Specification forAnalytical Data Interchange Protocol for MassSpectrometric Data1This standard is issued under the fixed designation E 2077; the number immediately following the designation indicates the year oforiginal adoption or, in the case of rev

    2、ision, 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 for massspectrometric data representation and a so

    3、ftware vehicle toeffect the transfer of mass spectrometric data between instru-ment data systems. This specification provides a protocoldesigned to benefit users of analytical instruments and increaselaboratory productivity and efficiency.1.2 The protocol in this specification provides a standard-iz

    4、ed format for the creation of raw data files, library spectrumfiles or results files. This standard format has the extension“.cdf” (derived from NetCDF). The contents of the file includetypical header information like instrument, sample, and acqui-sition method description, followed by raw, library

    5、or pro-cessed data. Once data have been written or converted to thisprotocol, they can be read and processed by software packagesthat support the protocol.1.3 This specification does not provide for the storage ofdata acquired simultaneous to and integrated with the massspectrometric data, but on ot

    6、her detectors; for example at-tached to the mass spectrometers liquid or gas chromato-graphic system. Related Specification E 1947 and Guide 1948describe the storage of 2-dimensional chromatographic data.1.4 The software transfer vehicle used for the protocol inthis specification is NetCDF, which wa

    7、s developed by theUnidata Program and is funded by the Division ofAtmosphericSciences of the National Science Foundation.21.5 The protocol in this specification is intended to (1)transfer data between various vendors instrument systems, (2)provide Laboratory Information Management Systems (LIMS)comm

    8、unications, (3) link data to document processing appli-cations, (4) link data to spreadsheet applications, and (5)archive analytical data, or a combination thereof. The protocolis a consistent, vendor independent data format that facilitatesthe analytical data interchange for these activities.1.6 Th

    9、e protocol consists of:1.6.1 This specification on mass spectrometric data, whichgives the full definitions for each one of the generic massspectrometric data elements used in implementation of theprotocol. It defines the analytical information categories, whichare a convenient way for sorting analy

It includes a brief introduction to using NetCDF anddescribes an API

Terminology3.1 Analytical Information ClassesThe Mass Spectrom-etry Information Model categorizes mass spectrometric infor-mation into a number of information “cla

    19、sses.” There is not adirect mapping of these classes into the implementation cat-egories described further below. The implementation catego-ries describe the information hierarchy; the classes describe thecontents within the hierarchy. The model presented here onlypartially addresses these classes.

    20、In particular, the last two(Processed Results and Component Quantitation Results) arenot described at all. Only Implementation Category 1 isrequired for compliance within this specification. Informationabout the other implementation categories is provided forhistorical interest. The classes defined

    21、here are:3.1.1 Administrativeinformation for administrative track-ing of experiments.3.1.2 Instrument-IDinformation about the instrument thatgenerally does not change from experiment to experiment.3.1.3 Sample Descriptioninformation describing thesample and its history, handling and processing.3.1.4

    22、 Test Methodall information used to generate the rawdata and processed results. This includes instrument control,detection, calibration, data processing and quantitation meth-ods.3.1.5 Raw Datathe data as stored in the data file, alongwith any parameters needed to describe it.3.1.6 Processed Results

    23、processing information and val-ues derived from the raw data.3.1.7 Component Quantitation Resultsindividual quanti-tation results for components in a complex mixture.3.2 Definitions for Administrative Information ClassThese definitions are for those data elements that are imple-mented in the protoco

    24、l. See Table 1.TABLE 1 Administrative Information ClassNOTE 1Particular analytical information categories (C1, C2, C3, C4,or C5) are assigned to each data element under the Category column. Themeaning of this category assignment is explained in Section 5.NOTE 2The Required column indicates whether a

    25、 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 Category 4 datasets.NOTE 3Unless other

    26、wise 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.NOTE 4A table is not to be interpreted as a table of keywords. Thesoftware implementation is independent of the data element names usedhere, a

    27、nd is in fact quite different. Likewise, the datatypes given are not animplementation representation, but a description of the form of the dataelement name. That is, a data element labeled as floating point may, forexample, be implemented as a double precision floating point number; inthis document,

    28、 it is sufficient to note it as floating point without referenceto precision.Data Element Name Datatype Category Requireddataset-completeness string C1 M12345protocol-template-revision string C1 M12345netcdf-revision string C1 M12345languages string C1 or C5 . . .administrative-comments string C1 or

Ex-pressed as the synthetic datetime given in the form:YYYYMMDDhhmmss6ffff.3.2.4.1 DiscussionThis is a synthesis of ISO 8601, whichcompensates for local time variations.3.2.4.2 DiscussionThe YYYYMMDDhhmmss

    35、 expressesthe local time, and time differential factor (ffff) expresses thehours and minutes between local time and the CoordinatedUniversal Time (UTC or Greenwich Mean Time, as dissemi-nated by time signals), as defined in ISO 8601. The timedifferential factor (ffff) is represented by a four-digit

    36、numberpreceded by a plus (+) or a minus () sign, indicating thenumber of hours and minutes that local time differs from theUTC. Local times vary throughout the world from UTC by asmuch as 1200 h (west of the Greenwich Meridian) and by asmuch as +1300 h (east of the Greenwich Meridian). When thetime

    37、differential factor equals zero, this indicates a zero hour,zero minute, and zero second difference from Greenwich MeanTime.3.2.4.3 DiscussionAn example of a value for a datetimewould be: 1991,08,01,12:30:23-0500 or 19910801123023-0500. In human terms this is 23 s past 12:30 PM on August 1,1991 in N

However, separators are not requiredand consequently shall not be used to separate date and time forinterc

    46、 files have an order orrelatedness between scans.3.2.10.3 DiscussionSome instruments are capable ofmixed mode data acquisition, for example, alternating positive/negative EI (Electron Ionisation) or CI (Chemical Ionisation)scans. In order to keep this interchange standard as simple aspossible, each

    47、scan mode must be treated as a separate dataset regardless of how the data are actually stored in the sourcedata file. Alternating positive/negative EI data, for example,will generate two interchange files (possibly simultaneously,depending on the implementation); one for the positive EIscans and on

    48、e for the negative EI scans. These files may bemade mutually cross-referential using their “external-file-references” fields.3.2.11 external-file-referencesan array of strings listingfile names referred to from within the raw data file.These couldinclude, for example, tune parameter, method, calibra
