QUALIFICATION OF AUTOMATIC TITRATORS

自动滴定仪的确认

Introduction 介绍

The present document is the 5th Annex of the core do cument “Qualification of Equipment”, and it should be used in combination with it when planning, performing and documenting the qualification process of automatic titrators.

The core document contains the Introduction and general forms for Level I and II of qualification, which are common to all type of instruments.

核心文件包括第一级和第二级确认的介绍和通用表格,适用于所有类型的仪器。

It is recommended, at Level II of qualification of the automatic titrators (Installation and release for use), to perform a gravimetric test of the volumes (10 selected volumes in a random way from 20 to 100% of the cylinder volume).

建议在自动滴定仪的第二级确认中(安装和使用放行),对体积进行重量检测(滴定管20%-100%体积随机选择10个)。

The present annex contains instrument-related recommendations on parameters to be checked at Level III and IV of qualification and the corresponding typical acceptance limits, as well as practical examples on the methodology that can be used to carry out these checks.

第三级周期性主动仪器检查

This Annex contains practical examples of tests and their associated tolerance limits for several parameters related to the performance of automatic titrators.

本附件包括了检查的实践性例子,及其相关的几个与自动滴定仪性能相关的参数的可接受标准。

These examples can be considered by the OMCLs as possible approaches to perform the Level III of the equipment qualification process: “Periodic and motivated instrument checks”.

这些例子可以被OMCL认为是仪器第三级别确认“周期性主动仪器检查”的方法。

GENERAL CONSIDERATIONS 总体考虑

—Due to the fact that a holistic approach has been taken, the verification of temperature probes and burettes is not included in this guideline, as the performance of these items is indirectly checked during the accuracy test.

—由于采用了整合功能的确认方法,本指南未包括温度探头和滴定管的确认,因为在准确度检查中,上述两项已经间接地被检查了。

—If available, the internal start-up test function may be used each time the instrument is switched on.

—如果可以的话,仪器内置开机检查功能在每次开机时可以使用。

—If several exchange units are used for different titrants, all units should be tested at Level III.

—如果有几个滴定单元用于不同的滴定剂,所有单元在第III级均需要检测。

—The limits and specifications of this guideline have been set according to Metrohm documentation. For other manufacturers (e.g. Mettler-Toledo, Mitsubishi, etc) the specifications may slightly differ.

—本指南的限度和标准根据万通相关文献进行设定。对于其它生产商(例如梅特勒-托利多、三菱等),标准可能稍有不同。

1. POTENTIOMETRIC TITRATORS 电位滴定仪

1.1. PRECISION 精密度

Materials:材料

Suitable certified standard RV (highly pure, dried), e.g. Benzoic acid RV or tris(hydroxymethyl)- aminomethane (TRIS).

合适的标准品RV(高纯,干燥),例如苯甲酸RV或三(羟甲基)氨基甲烷(TRIS)

Fresh titrant, appropriate to titrate the selected standard.

费休滴定剂,适宜滴定选择的标准

Method:方法

Perform a minimum of 3 titrations with 3 independent additions of certified standard (in random order if using different weights), which should result in a consumption of approx. 20 % to 90 % of the burette volume.

独立加入3次计量过的标准物质(如果重量不同的话,顺序可以随机),进行至少3次滴定,消耗的滴定剂的体积应控制在一管体积的20%-90%。

Note: If necessary, for lower volume burettes, increase the molarity of the titrant (for example, from 0.1 to 1.0M) to minimize the weighing error of the standard.

注:如有必要,对于小容量滴管,增加滴定剂的浓度(如从0.1增加到1.0M)以减少标准的称量误差。

Calculate the relative standard deviation of the titers obtained.

计算所得的滴定度的相对标准偏差(RSD)。

If available, this calculation can be performed directly with the built-in statistics function of the instrument.

如果可以的话,该计算可以由仪器的内置统计功能计算得到。

Limits: RSD ≤ 0.2 %

限度:RSD ≤ 0.2 %

1.2. ACCURACY 准确度

Materials:材料

Refer to chapter 1.1. Precision.参照第1.1章精密度

The accuracy of the results obtained depends on the content of the certified standard guaranteed by its manufacturer.

所得结果的准确性依赖于标准物质供应商所保证的含量。

Calculation of the theoretical titer value as a function of temperature:

对滴定度受温度影响的计算

The theoretical titer value of the titrant solution at 20℃is 1.000, with a reduction in the titer of

0.02 % per degree of temperature rise, according to the following formula:

滴定剂溶液在20℃时理论滴定度为1.000,根据以下公式进行计算,每升高一度,则滴定度会下降0.02%。

Titer theoretical (at X℃) = 1.000 + 0.0002 (20 – x)

理论滴定度(在X度时)= 1.000 + 0.0002(20-X)

Where:其中

x = mean of the initial and final temperature of the titrant solution (at the beginning and at the end of the measurement), in °C.

X = 滴定剂溶液起始和结束温度(在测量开始和结束时),℃

Note: The stated formula is only applicable for aqueous titrant solutions (see Application Bulletin No. 252, Metrohm). For example, the given reduction in the titer of Perchloric acid is 0.1% per degree of temperature rise.

注:所给定的公式只用于水相滴定溶液(见第252号应用公告,万通)。例如,高氯酸滴定液给定的温度膨胀系数为每升高一度,浓度降低0.1%。

Method:方法

Perform a minimum of 3 titrations with 3 different weights of certified standard.

称量三份标准物质,进行至少三次滴定。

Note: Results from the precision test (see 1.1.) can be used.

Limits:限度

The systematic deviation (d rel) should be maximum≤±0.5 % (when using a freshly opened titrant container).

系统误差应≤±0.5 %(如果使用新开的滴定剂的话)

1.3. LINEARITY 线性

Materials:材料

Refer to chapter 1.1. Precision. 参见第1.1章精密度

Method: Linear regression volume/sample size

方法:线性回归体积/样品量

Calculate a linear regression of the titrant volume in ml (y-coordinate), versus the weight of the certified standard in g (x-coordinate) on a minimum of 5 weights.

以滴定体积(ml)为y轴,对标准品重量(g)为x轴计算线性回归方程式,至少需要五个重量数据。

Limits: r2≥ 0.9990.

限度:r2≥ 0.9990.

Note: In addition, using the same linearity data, systematic errors can be evaluated, as the y axis intercept of the linear regression Titrant volume in ml/Sample size in g (a sys), and the slope of the linear regression Titer in M/Titrant volume in ml (b T/Vol).

注:另外,如果使用相同的线性数据,可以评估系统错误,因为y轴截距为滴定体积(ml)/样品重量(g)(a sys),线性回归的斜率为滴定度(M)/滴定体积(ml)(b T/Vol)。

Limits: 限度

a sys <±10 μl for 1 ml-burettes; a sys<±50μl for 5, 10, 20 and 50 ml-burettes

管道专业术语常用英语单词 在引进装置、涉外及中外合资技术改造工程的技术资料中,经常要接触到英语单词。由于管道安装涉及多项工程技术,而不从属于任何一项工程技术分支,故其技术性质有一定特殊性,不少英语词汇是在实践中逐渐形成的,借助一般科技英汉词典有时也难以找到它们的确切含意。现将管道安装工程中出现较多的单词整理列出,如果能熟悉这些单词,对阅英文图纸能收到事半功倍的效果。 一、专业名词术语 设计图 施工图 平面图 立面图 轴测图、透视图 详图、大样图、接点图 修改图竣工图图名 图号 比例 温度 设计温度 湿度 流量 流速 摄氏温度ayout; design final plan elevation isometric drawing;detail drawing record drawing as-completed drawing; as-built drawing title drawn No. scale temperature design temperature humidity flow flow velocity ? ? 毛重 净重 支座 支架 吊架 间距 跨距 焊接 焊缝 石棉水泥 接口 青铅接口 承口、大 头 插口、小 头 压力试验 水压试验 gross weight net weight saddle support cradle distance; clearance; spacing span welding weld; welding seam; bead asbestos-cement joint lead joint hub; bell; socket spigot pressure test hydraulic test
