To facilitate just and sound decisions legal measurements must be reliable. The aim of this paper is to explore how this is
currently achieved and how it might be better done. It considers the different types of legal proceedings, the role of chemical
measurement, level of proof, the different types of chemical measurement, measurement units, the role of government, the chemical
measurement industry and its control, legal metrology and the development of a measurement system based on metrological principles.
It is argued that recent developments provide the basis for a robust support system, that but more needs to be done. It is
also argued that the conventional approach to legal metrology has little place in chemical measurement, but that some controls
are needed in some areas. In particular, a harmonised approach to international measurement standards is advocated.

A goal of clinical laboratory science is to produce accurate and comparable patient test results for a specimen independent
of analytical methodology. The In Vitro Diagnostics Directive in Europe has provided the impetus for the U.S. in vitro diagnostic
(IVD) industry to adapt the concepts of Metrology, the science of measurement, including measurement traceability and measurement
uncertainty. The joint committee for traceability in laboratory medicine has provided a valuable database of internationally
recognized reference materials and methods and reference laboratories. Much of the responsibility for measurement traceability
falls on IVD manufacturers, but all global stakeholders, including the clinical laboratory profession, government Regulatory
bodies, metrology institutes, and the providers of EQA/PT surveys, must cooperate to progress toward this goal. The adaptation
of the concepts of Metrology to the clinical laboratory is an appropriate and logical development and it will continue in
the twenty-first century. 相似文献

Stoichiometry of analytical reactions is discussed as an important element of many primary methods (gravimetry, volumetry,
spectrophotometry, etc.) and therefore, of chemical metrology as a whole. Variations in stoichiometry caused by non-equilibrium
conditions, by changes in the reaction medium or by other factors can be a source of the dominant uncertainty component in
the analytical measurement. Such a situation is illustrated with the Karl Fischer (KF) reaction which is widely used in aquametry.
Two kinds of solvents used as a part of the reaction medium – alcohols and amides – are compared. The influence of the media
on the stoichiometry of the reaction and, correspondingly, on the titre of the KF reagent is evaluated.

National measurement systems are infrastructures to ensure, for each nation, a consistent and internationally recognised
basis for measurement. Such complex systems have historical, technical, legal, organisational and institutional aspects to
connect scientific metrology with practical measurements. Underlying any valid measurement is a chain of comparisons linking
the measurement to an accepted standard. The ways the links are forged and the etalons (measurement standards) to which they
connect are defining characteristics of all measurement systems. This is often referred to as traceability which aims at basing
measurements in common measurement units – a key issue for the integration of quantitative chemical analysis with the evolving
physical and engineering measurement systems. Adequate traceability and metrological control make possible new technical capabilities
and new levels of quality assurance and confidence by users in the accuracy and integrity of quantitative analytical results.
Traceability for chemical measurements is difficult to achieve and harder to demonstrate. The supply of appropriate etalons
is critical to the development of metrology systems for chemical analysis. An approach is suggested that involves the development
of networks of specialised reference laboratories able to make matrix-independent reference measurements on submitted samples,
which may then be used as reference materials by an originating laboratory using its practical measurement procedures.

The global recognition that quality is an economic issue is requiring analytical chemists to look at the chemical measurement process in a way that has not been done before. Much work has been done in certifying reference materials, writing measurement protocols, creating measurement networks, developing analytical measurement techniques and other efforts to make good measurements. This article explores the meaning of quality in chemical measurements and discusses quality in terms of credibility, reliability, traceability and comparability. The importance of understanding the contribution of comparability and traceability to quality in chemical measurements and chemical metrology is emphasized. 相似文献

Establishment of the traceability and the evaluation of the uncertainty of the result of a measurement are essential in order
to establish its comparability and fitness for purpose. There are both similarities and differences in the way that the concepts
of traceability and uncertainty have been utilised in physical and chemical measurement. The International Committee of Weights
and Measures (CIPM) have only in the last decade set up programmes in chemical metrology similar to those that have been in
existence for physical metrology for over a century. However, analytical chemists over that same period have also developed
techniques, based on the concepts of traceability and uncertainty, to ensure that their results are comparable and fit for
purpose. This paper contrasts these developments in physical and chemical metrology and identifies areas where these two disciplines
can learn from each other. 相似文献

As a consequence of the globalisation of trade and industry and other human activities, reliability of and confidence in measurement results is increasingly required, also in the field of chemical analysis, so that measurements made in one country will be accepted in other countries without the necessity to repeat them. The prerequisite for confidence is comparability on the basis of known uncertainties which in turn are based on traceability to recognised references. Traceability structures for chemical measurements are required which, by providing calibration means traceable to national standards, allow uncertainty statements to be made at field level, thus establishing comparability. Such traceability structures are now being developed in all industrialised countries. To ensure international comparability, mutual recognition of the national activities in metrology in chemistry is required in addition. The Mutual Recognition Agreement (MRA) for national measurement standards and calibration certificates issued by national metrology institutes, which is currently under way within the framework of the Metre Convention, aimes at providing the necessary international confidence for all kinds of measurements. The field of chemical analysis is included in the international metrological infrastructure through the new Consultative Committee for Amount of Substance (CCQM). Carefully selected key comparison measurements, which cover the most important areas where traceability is required, and which are carried out by national metrology institutes in cooperation with other national institutes entrusted with the provision of part of the national references for chemical measurements, form the basis for declarations of equivalence under the MRA. The results of the first key comparisons and studies carried out so far clearly show that the group of laboratories involved in the key comparisons is capable of establishing the international references (key comparison reference values) for chemical measurements with sufficient accuracy, also in complicated matrices. 相似文献
