The precision of an analytical procedure is usually expressed as the standard deviation or relative standard deviation (coefficient of variation) of a series of measurements. Precision may be a measure of either the degree of reproducibility or of repeatability of the analytical procedure under normal operating conditions. In this context, reproducibility refers to the use of the analytical procedure in different laboratories, as in a collaborative study. Intermediate precision (also known as ruggedness) expresses withinlaboratory variation, as on different days, or with different analysts or equipment within the same laboratory. Repeatability refers to the use of the analytical procedure within a laboratory over a short period of time using the same analyst with the same equipment.定義—分析方法的精密度是單個檢測結(jié)果間的一致程度,當方法重復使用于同一樣品的多個樣品時。精密度可以是在正常操作條件下,分析方法重現(xiàn)性和重復性程度的測量。中間精密度(通常也稱為粗放性)表述的是在同一實驗室范圍內(nèi)的變化,不同的天數(shù),不同的分析人員或相同實驗室內(nèi)的不同儀器。Chromatography其可以評估。對于色譜方法,至關重要的。Data Elements Required for Validation驗證需求數(shù)據(jù)組成Compendial test requirements vary from highly exacting analytical determinations to subjective evaluation of attributes. Considering this broad variety, it is only logical that different test procedures require different validation schemes. This chapter covers only the most mon categories of tests for which validation data should be required. These categories are as follows:法定的檢測要求從高度萃取的分析測定到特征的主觀評價變化。本章節(jié)包括了最常用的檢測分類,驗證資料中需求。Category II—Analytical procedures for determination of impurities in bulk drug substances or degradation pounds in finished pharmaceutical products.分類 II——原料藥中雜質(zhì)或成品中降解物的測定These procedures include quantitative assays and limit tests.這些方法包括定量地含量測定和限度測定。Table 2表2中列出是每一分類需求的數(shù)據(jù)組成。 May be required, depending on the nature of the specific test.lVerification of Compendial Proceduresfor principles relative to the verification of pendial procedures).
