One of the more technically challenging concepts in quality assurance is the appropriate quantification of the uncertainty of measurement. Consequently, there must be an adequate emphasis on didactic approaches to ascertain that the student is not ju...
It is accepted that the COVID-19 pandemic opened the interest for open learning/education, for which there are three accepted meanings: (i) open universities, (ii) massive open online courses (MOOCs), and (iii) open educational resources (OERs). In t...
Analytical chemistry is experiencing dramatic, turbulent change beyond laboratory and laboratory management control. Technological innovations, staffing demographics, new business models, automation, industry consolidation, society, regulatory expect...
Over the last few decades, the operation of the Single European Market and the task to eliminate technical barriers to trade underlined the need for adequate and reliable quality infrastructure. [...]
Reliable, traceable, and comparable measurements provide a rational basis for evaluating the quality of any result and the starting point for laboratory accreditation. Accurate and compatible measurements are, at present, essential for manufacturing,...
When using a method routinely in a laboratory to deliver measurement results daily to a factory to monitor a process, we can have several scenarios. [...]
Many analytical measurements are made in order to check a system or product for conformity [...]
The basic principles of metrology (the science of measurement) are the same across disciplines. [...]
Established in 1989, the aim of Eurachem is to provide a focus for analytical chemistry and [...]
Quality represents all the characteristics and features of a product or service that satisfies individual requirements. In other words, quality is measured by the degree of customer satisfaction regarding a product or service. The implementation of t...
Interleukins proved to be valuable biomarkers for different diseases. Interleukins 1β, 6, and 12 can be used as biomarkers for brain cancer diagnosis, and therefore this paper proposed a needle stochastic sensor based on protoporphyrin IX immobi...
We report the statistical parameters associated with the dynamic characteristics of a calcium microelectrode. The electrochemical behavior of the obtained microsensor was assessed against the main interferents.
The master’s degree in Applied Analytical Chemistry at University College London (UCL) includes valuable teaching input from the UK National Measurement Laboratory for Chemical and Bio-Measurement hosted at LGC. The course starts by introducing...
This communication presents the teaching experience of Ricardo Bettencourt da Silva in the scientific areas of metrology and examinology in chemistry at various universities.
: We identified and quantified by LC-MS/MS 11 (quercetin, galangin, pinocembrin, kaempferol, vanillin, chrysin, gallic acid, p-coumaric acid, trans-ferulic acid, caffeic acid, and caffeic acid phenethyl ester) out of the 21 polyphenolic compounds we...
Virtual screening of compound libraries for property predictions has various applications such as: prediction of oxido-reduction potentials in view of molecular recognition, drug-likeness assessment, and design of new potential therapeutic agents, q...
Matrix-induced signal suppression or enhancements are known phenomena in electrospray ionization mass spectrometry. Very few studies report on method development for organic aerosols analyses with the evaluation of the matrix effects. The matrix effe...
Laboratory quality management system is a concept of utmost importance for industry and other economic sectors. Nowadays, even for university laboratories it is possible to have accredited tests according to standard ISO/IEC 17025. This paper demonst...
Quality and reliability are essential terms in analytical chemistry. Reliable analytical information implies quality. Maintaining the quality in time shows reliability. Evaluation of quality and reliability is essential for the validation of a new me...
The correlation between the measured values of product components can influence the total risk of false decisions in conformity assessment. This correlation can originate from the characteristics of the product (intrinsic) or from how the components...
The aim of this work was to investigate the corrosion inhibition effect of natural seaweeds in seawater on carbon steel. The corrosion efficiency of carbon steel in the absence and the presence of natural seaweeds in seawater was evaluated by the gra...
The (International Atomic Energy Agency) IAEA’s fundamental safety objective is to protect people and the environment from harmful effects of ionizing radiation. The safety principles apply to all facilities and all activities to reduce existing radi...
Experience with the implementation of a quality management system (QMS) at the research laboratory of a public university in the Czech Republic will be presented in this talk. [...]
Nanolayer deposition(s) of Ag and AgC composite on a plastic substrate was used to design disposable stochastic sensors. The first sensor was based on an Ag nanofilm deposited on plastic; for the second sensor, an AgC composite was deposited on plast...
