USP1058分析儀器的確認(rèn)

1、分析儀器的確認(rèn)(USP39-NF34 Page1055)INTRODUCTION'SA large variety of laboratory equipment, instruments, and computerized analytical systems, ranging from simple nitrogen evaporators to complex multiple-function technologies (see Instrument Categories ), are used in the pharmaceutical industry to acquire

2、 data to help ensure that products are suitable for their intended use. An analyst's objective is to consistently obtain reliable and valid data suitable for the intended purpose. Depending on the applications, users validate their procedures, calibrate their instruments, and perform additional

3、instrument checks, such as system suitability tests and analysis of in-process quality control check samples to help ensure that the acquired data are reliable. With the increasing sophistication and automation of analytical instruments, an increasing demand has been placed on users to qualify their

4、 instruments.各種各樣的實(shí)驗(yàn)室設(shè)備、儀器、 計(jì)算機(jī)化分析系統(tǒng)，從簡(jiǎn)單的氮吹儀到復(fù)雜的多功能技術(shù)(見(jiàn)Instrument Categories )，均被用于制藥行業(yè)，以獲得數(shù)據(jù)來(lái)確保產(chǎn)品達(dá)到預(yù)期用途。分析的目的是持續(xù)獲得符合預(yù)期目的的可靠的有效數(shù)據(jù)?；趯?shí)際應(yīng)用，使用者進(jìn)行工藝驗(yàn)證、儀器校準(zhǔn)，并進(jìn)行額外的儀器檢核，如系統(tǒng)適用性試驗(yàn)和中間質(zhì)量控制分析檢查樣品，以確保所獲得數(shù)據(jù)的可靠性。隨著分析儀器的日益復(fù)雜化和自動(dòng)化，對(duì)儀器確認(rèn)的要求也在不斷增加。Unlike method validation and system suitability activities, analytical

Competing opinions exist regarding instrument qualification and validation procedures and the roles and responsibilities of those who perform them. Consequently, various approaches have been used for instrument qualifi

6、cation, approaches that require varying amounts of resources and generate widely differing amounts of documentation. This chapter provides a scientific approach to AIQ and considers AIQ as one of the major components required for generating reliable and consistent data. Note that the amount of rigor

7、 applied to the qualification process will depend on the complexity and intended use of the instrumentation.This approach emphasizes AIQ's place in the overall process of obtaining reliable data from analytical instruments.不同于方法學(xué)驗(yàn)證和系統(tǒng)適用性試驗(yàn)，分析儀器確認(rèn)（AIQ）目前并沒(méi)有明確的 指導(dǎo)和規(guī)程。關(guān)于儀器確認(rèn)和驗(yàn)證程序，以及執(zhí)行它們的角色和職責(zé)，存在著互

8、相矛盾的觀點(diǎn)。由此導(dǎo)致，已有多種方法應(yīng)用于儀器確認(rèn)，而這些方法需要使用 的資源數(shù)量各異并產(chǎn)生數(shù)量差異巨大的文件。本節(jié)為分析儀器確認(rèn)（AIQ）提供了科學(xué)的方法，并將分析儀器確認(rèn)（AIQ）作為產(chǎn)生可靠性和一致性數(shù)據(jù)的重要 組成部分。注意，精確應(yīng)用于確認(rèn)工序的程度取決于儀器的復(fù)雜程度和預(yù)期用途。這種方法強(qiáng)調(diào)了 AIQ從分析儀器中獲得可靠數(shù)據(jù)的全過(guò)程中的地位。Validation versus Qualification 驗(yàn)證 vs 確認(rèn)In this chapter, the term validation is used for manufacturing processes, analytica

9、l procedures, and software procedures and the term qualification is used for instruments. Thus, the phrase "analytical instrument qualification ” （AIQ） is used for the proce ss of ensuring that an instrument is suitable for its intended application.在本節(jié)中，驗(yàn)證一詞用于生產(chǎn)工藝、分析方法及軟件程序中，而確認(rèn)一詞則用于 儀器。因此，”分析儀

Each layer adds to the overall quality. Analytical

11、 instrument qualification forms the base for generating quality data. The other components essential for generating quality data are analytical method validation, system suitability tests, and quality control check samples. These quality components are described below.組成可靠和一致數(shù)據(jù)（質(zhì)量數(shù)據(jù)）的有四個(gè)關(guān)鍵部分。圖1將這些部分

Some analyses also require the inclusion of quality control check samples to provide an in-process or ongoing assurance

18、 of the test's suitable performance. In this manner, AIQ and analytical method validation contribute to the quality of analysis before analysts conduct the tests. System suitability tests and quality control checks help ensure the quality of analytical results immediately before or during sample

19、 analysis.許多分析員用經(jīng)標(biāo)準(zhǔn)物質(zhì)和/或校準(zhǔn)標(biāo)準(zhǔn)品校準(zhǔn)后的儀器進(jìn)行測(cè)試。有些分析員 還要求添加質(zhì)量控制檢查樣品來(lái)保證試驗(yàn)過(guò)程中或持續(xù)的試驗(yàn)適用性。通過(guò)這種方式，AIQ和分析方法驗(yàn)證在測(cè)試前提高了分析的質(zhì)量。系統(tǒng)適用性試驗(yàn)和質(zhì)量 控制檢查則在樣品分析前或過(guò)程中確保了分析結(jié)果的質(zhì)量ANALYTICAL INSTRUMENT QUALIFICATION PROCESS分析儀器確認(rèn)程序The following sections address in detail the AIQ process.

21、d results from several discrete activities. For convenience, these activities can be grouped into four phases: design qualification (DQ), installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ).儀器確認(rèn)并非一個(gè)單獨(dú)連續(xù)的過(guò)程， 而是若干個(gè)獨(dú)立處理的結(jié)果。方便起見(jiàn)，這 些處理可分為四個(gè)階段：設(shè)計(jì)確認(rèn)(DQ、安裝確認(rèn)(I

22、Q)、運(yùn)行確認(rèn)(OQ、 性能確認(rèn)(PQ 。SomeAIQ activities cover more than one qualification phase, and analysts potentially could perform them during more than one of the phases (see Table 1 ). However, in many instances there is need for specific order to the AIQ activities; for example, installation qualification m

The AIQ activities will be defined and documented.一些AIQ涵蓋多個(gè)確認(rèn)階段，分析員傾向于進(jìn)行多個(gè)階段的確認(rèn)(見(jiàn)表 1)。然 而，在很多情況下，AIQ有特定順序要求；比如，必須先進(jìn)行安裝確認(rèn)才能開(kāi)始 實(shí)施其它確認(rèn)。AIQ將被定義并以文件形式記錄。Table 1.

31、l specifications of the instrument and criteria for selection of the vendor, based on the intended purpose of the instrument. Design qualification (DQ) may be performed not only by the instrument developer or manufacturer but also may be performed by the user. The manufacturer is generally responsib

32、le for robust design and maintaining information describing how the analytical instrument is manufactured (design specifications, functional requirements, etc.) and tested before shipment to users. Nonetheless, the user should ensure that commercial off-the-shelf (COTS) instruments are suitable for

33、their intended application and that the manufacturer has adopted a quality system that provides for reliable equipment. Users should also determine the manufacturer's capability for support installation, services, and training. This determination might be aided by the user's previousinteract

Testing activities in the OQ phase may consist of these test parameters.IQ成功后，儀器即可進(jìn)行OQ1認(rèn)。運(yùn)彳T確認(rèn)(OQ是證實(shí)儀器具有在選定環(huán)境 中按照其操作規(guī)范運(yùn)行的功能。OQt段的測(cè)試包含了這些測(cè)試參數(shù)。Fixed Parameters These tests measure the instrument's nonchanging parameters such as length, height, weight, voltage

46、 inputs, acceptable pressures, and loads. If the manufacturer-supplied specifications for these parameters satisfy the user, the test requirements may be waived.However, if the user wants to confirm the parameters, testing can be performed at the user's site. Fixed parameters do not change over

47、the life of the instrument, and therefore never need redetermination. NOTEThese tests could also be performed during the IQ phase (seeTable 1 );if so, fixed parameters need not be redetermined as part of OQtesting. 固定參數(shù)一這些測(cè)試測(cè)量?jī)x器的不變參數(shù)，如長(zhǎng)度、高度、重量、輸入電壓、可 接受壓力和負(fù)荷。如果制造商提供的這些參數(shù)規(guī)格符合用戶(hù)要求，就可以免除測(cè) 試。但用戶(hù)如果需要確認(rèn)這些

48、參數(shù)，可以在用戶(hù)的場(chǎng)地進(jìn)行測(cè)試。固定參數(shù)在儀器壽命周期內(nèi)保持不變，因此無(wú)需重測(cè)。注：這些測(cè)試也可在IQ階段進(jìn)行（見(jiàn) 表1）;如此一來(lái)，固定參數(shù)就無(wú)需在OQM試部分重測(cè)。Secure Data Storage, Backup, and Archiving Whenapplicable, test secure data handling such as storage, backup, audit trails, and archiving at the user's site according to written procedures.安全數(shù)據(jù)儲(chǔ)存、備份和歸檔當(dāng)適用時(shí)，可根據(jù)書(shū)面程
