Instrument calibration

Ebook "Metrology in chemistry" presents the essentials every chemist needs to know about how to obtain reliable measurement results. Starting with the basics of metrology and the metrological infrastructure, all relevant topics – such as traceability, calibration, chemical reference materials, validation and uncertainty – are covered. In addition, key aspects of laboratory management, including quality management, inter-laboratory comparisons, proficiency testing, and accreditation, are addressed.

The combination of potentiometric methods with multivariate calibration techniques allows complex mixtures to be analyzed. In this study, a new method was developed and reported for simultaneous determination of copper(II) and zinc(II) cations in a mixture by titrimetric methods. The developed method permits simultaneous cation analysis with low detection limits, just by using a pH electrode. This work has achieved the challenging goal of developing a cost-effective and applicable method that can be applied in most laboratories due to independence of any chemical instruments.

In this paper, we discuss the current situation of AWS and ARG network in VNMHA. Next, we will explain the maintenance and cyclic calibration of the instrument proposed in this project. Furthermore, we will explain the installation plan of the ARGs to calibrate two radar data in Phu Lien and Vinh for the development of QPE. Installation of ARGs has been achieved with cooperative works of VNMHA staffs and JICA experts. So, we introduce their activities for each step from site survey to pre–operational evaluation.

The spectrum weighted responses of various detectors were calculated to provide guidance on the proper selection and use of survey instruments on the basis of their energy response characteristics on the neutron fields. To yield the spectrum weighted response, the detector response functions of 17 neutron-measuring devices were numerically folded with each of the produced calibration neutron spectra through the in-house developed software ‘K-SWR’.

This work provides a comprehensive overview of the calibration of DWRNPM channels by describing the configuration of the DWRNPM system and by summarizing the theories of operation and the reference power estimation methods with their associated calibration procedure. The calibration procedure was actually performed during the commissioning of an open-pool type research reactor, and the results and experience are documented herein.

Defining the limits of accuracy for all measuring instruments. The limits of measurement must be better than the required limits for the product, process and safety. If the measuring instrument fails to meet calibration limits then the product, process or safety could have been compromised. If a factor of two is set, and if the measuring instrument fails calibration there is a margin allowed before any quality issues are raised. The factor should be as large as possible, the larger the factor the greater the safety margin.

This text started out many years ago as a lab-based text, one of the first such published by ISA—titled Basic Electrical Measurements and Calibration—in 1978, nearly 28 years ago. Many things in the electrical/ electronics industry have changed since this first edition was published. In the years following publication, digital instrumentation has become affordable, widespread, and has almost totally displaced analog devices in automation. While analog instruments have not completely disappeared, it is no longer the technology of choice for current automation installations....

Banking sector reforms have been sequenced to correspond with changing regulations of the foreign exchange market. The government has allowed the exchange rate to gradually float (as opposed to a “crawling” peg), and full current account convertibility has been introduced, with de facto capital account convertibility for nonresidents, and calibrated liberalization for residents.

I have been associated with uncertainty calculations for quite sometime. Asia Metrology Program (APMP) took interest in unification of expressing the measurement results along with uncertainty. In those days the uncertainty components were divided according to source of errors. The errors were named as random and systematic errors. Hence components of uncertainty were named random uncertainty and systematic uncertainty. Around 1980, BIPM took initiative by circulating questioners to the countries who were members of Metre Convention.

Ours is a very young profession: when the first edition of the Instrument Engineers’ Handbook (IEH) came out, Marks’ Mechanical Engineers’ Handbook was in its fifth edition, and Perry’s Chemical Engineers’ Handbook was in its sixth! Now, as we are starting to work on the fourth edition of the IEH, we are already in a new millenium. But while our profession is young, we are also unique and special.
