A ‘Periodic Table’ of mass spectrometry instrumentation and acronyms

The number of acronyms in mass spectrometry (MS) and hyphenated techniques are growing rapidly. The ever-widening range of users of MS technology has led to variations in terminology and how it has been applied. The International Union of Pure and Applied Chemistry (IUPAC) has undertaken a review of MS nomenclature resulting in an extensive publication, describing over 500 terms, and is the defining resource for mass spectrometrists. However, for less experienced users of MS, this IUPAC document may require greater explanation as it is not intended to explain the basis of these terms. Given this, the Analytical Methods Committee (AMC) of the Royal Society of Chemistry highlighted an alternative text was required to help understand these terms, how and why they are used in combination, that may be accessible to non-MS experts. This manuscript describes the structure of typical MS instrumentation (sample introduction, ionisation source, mass analyser, detector, data acquisition/processing) and hyphenated technologies whereby each section is discussed and summarised in context and presented as a recognisable tabulated format

Colorimetric Solid-Phase Extraction Method for Cu(II) Ion Determination Using 2-Hydroxybenzaldehyde Benzoylhydrazone as Sensing Reagent

A new sensor based on the use of 2-hydroxybenzaldehyde benzoylhydrazone as a colorimetric reagent immobilized onto styrenedivinylbenzene disks has been carried out for the determination of Cu(II) ions within several minutes. The sensor is designed on a rapid and easy two-step procedure: (1) the extraction of Cu(II) ions onto a disk loaded with the copper-selective colorimetric reagent and (2) the determination of the complexed analyte directly on the surface of the disk using diffuse reflectance measurements at 400 nm. The color of the disk changed from white to green in the presence of Cu(II) ions. The work herein details the optimization of the sensing system employing a fractional factorial design 33-1 considering three variables (pH, immobilization time, and amount of ligand immobilized onto the disk). The Pareto chart and response surfaces in a spherical domain indicated that the optimum conditions for the sensing of copper ions were pH ¼ 7, with a ligand immobilization time of 10 min and 6.25 mg of reagent loaded onto the disk. Under the optimum conditions, the analytical parameters of the proposed method were determined. The calibration graph was linear over the range of 0 to 2.5 mg L 1 of Cu(II) with a detection limit of 0.21 mg L 1. The relative standard deviation for six measurements of 1 mg L 1 of Cu(II) was found to be 4.87%. The interference from inorganic salts and other metals was found not to be of major concern when monitoring copper ions in water samples. The simplicity and rapidity of this technique make it convenient and amenable for on-site and routine analysis

Understanding Uncertainties in Thermographic Imaging

7 p.The present article proposes a workflow based on free/open-source software solutions for the acquisition of competences in engineering courses related to the use of thermographic images. The approach is aimed to three-dimensional visualization techniques over thermographic images to improve the comprehension and interpretation of the different error sources that affects the measurements, and therefore the conclusions and analysis derived from them. The present work is framed inside the virtual laboratories discipline, as the new learning material can be employed for the acquisition of competences and skills. Additionally, it can be used for the evaluation of competences in asynchronous and e-learning programs. The learning materials could be easily deployed in a learning management system, allowing the students to work with the models by means of open-source solutions easily, both in asynchronous and face-to-face courses. Consequently, the present approach will improve the application of professional techniques, so the future professionals will reach the working market better prepared.S

Science Notes - Tenth International Conference on Chemical Education

The Tenth International Conference on Chemical Education (10th ICCE) will be held August 20-25, 1989, at the University of Waterloo in Ontario, Canada. The conference is co-sponsored by the Chemistry Teaching Committee of the International Union of Pure and Applied Chemistry; and the Canadian Society for Chemistry and is supported by UNESCO. It is co-chaired by Maurice Chastrette (Chairman of CTC/IUPAC, France) and Brian T. Newbold (Canada)

Growing the FAIR Community at the Intersection of the Geosciences and Pure and Applied Chemistry

The geoscience and chemistry communities have numerous common practices and dependency on data standards. Recent efforts from the International Union on Pure and Applied Chemistry (IUPAC) and the American Geophysical Union (AGU) are to explore and collaborate on approaches and sharing lessons learned on efforts to implement the FAIR Guiding Principles as they apply to data in their respective communities. This paper summarizes their efforts-to-date highlighting the importance of existing communities, Scientific Unions, standards bodies and societies in taking deliberate steps to move and encourage researcher adoption of the FAIR tenets

Translation of Organic Compound to 2D Graphical Representation using SDT

IUPAC (The International Union of Pure and Applied Chemistry) customary is employed to explain structure and characteristic of chemical compound. This paper describes translation of IUPAC (International Union of Pure and Applied Chemistry) name into Two-dimensional structure of substance that consists of graphical entities. OpenGL graphical language is wont to generate graphical structure of IUPAC name. Chemical names square measure a typical manner of act chemical structure data. Basic graphical entities square measure wont to generate 2nd graphical structure of IUPAC name from Intermediate Graphical Language. computer file is generated on analyzing IUPAC name. computer file is OpenGL graphical functions to show graphical entities. This translation is achieved victimisation Syntax – Directed Translation theme by associating linguistics action. This offers internet 2nd graphical illustration of IUPAC name. This paper proposes a strategy for achieving this translation. DOI: 10.17762/ijritcc2321-8169.150512
