Analytical Measurements Should be Made to Satisfy an Agreed Essay

Analytical Measurements Should be Made to Satisfy an Agreed Requirement - Essay Exampleb.Prior to making a final judgement the results thus obtained from measurements should be compared to the existing standards already laid down to interpret the lower and upper localises. For example, in determining the level of alcohol in the blood of a number one wood charged with driving while drunk, there should be an existing standard level of alcohol in blood considered safe for driving and a limit above which it is unsafe to drive. The result obtained from the blood sample of this driver is therefore compared to the standard limit. (4, 10)c.A valid measurement is the one which does not result in tawdry an observer, or the customer of a laboratory making the measurement. That is to say, that if the customer makes a decision relying on the information obtained by a valid measurement then the decision is correct. (4, 10)d.A valid measurement in itself may not be dieicularly accurate or prec ise, but if a conclusion is to be reached as to how the result differs from a standard then the measurement leave have sufficient accuracy and precision to satisfy customers requirement. The correctness of a decision reached by relying on the information obtained through analytical measurement indicates the validity of measurement. (1, 4, 10)e.The aim of the agency making Valid Measurement, normally a laboratory, is to suffer their customers with results that are not ambiguous and confusing and meet customer requirements. That is why Analytical Measurement should be made to satisfy an agreed requirement. (10)In analytical measurements the quality of data extracted is all that matters and good information thus gained is an come out of the closetcome of good measuring techniques applied. For data to be of good quality the technique sedulous should be validated by being precise, repeatable, reproducible and stable. (8,9)g. A precise technique does not have deviations in the result of same measurement. There should be no change in methodology of measurement and neither should there be a change in what is being measured. The repeatable technique should move over the same result when the same object is measured over a number of times. A reproducible technique is the one which when repeated produces the same result. A stable technique does not change over a period of time and if repeated, in times to come, it should be able to give same results as in the past. (2, 5)h. Laboratory of the Government Chemist (LGC) and National Physical Laboratory (NPL) have jointly developed Valid Analytical Measurement (VAM) principles, as part of their VAM programme to sketch a design for laboratories involved in making analytical measurements. Out of the six principles as laid down Analytical measurements should be made to satisfy an agreed requirement (4) is the first. (4)i. To realize the importance of agreed requirements consider that there a number of tests which can be perf ormed to carry out a measurement. An analyst, being an expert, must enter into a dialogue with the customer to discuss the quality of results, time and cost of these tests. The analyst must have the association to identify customers requirements. Moreover, it is important to gain an insight into the criticality of the measurement by virtue of discussion with the customer. As such, it becomes necessary to know for what purpose the result will be used. (4, 5, 6)j. All critical and non-critical issues must be explained to the customer prior
