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

Food Physical Chemistry and Biophysical Chemistry

Food Physical Chemistry is considered to be a branch of Food Chemistry^1,2^ concerned with the study of both physical and chemical interactions in foods in terms of physical and chemical principles applied to food systems, as well as the applications of physical/chemical techniques and instrumentation for the study of foods^3,4,5,6^. This field encompasses the "physiochemical principles of the reactions and conversions that occur during the manufacture, handling, and storage of foods"^7^. Two rapidly growing, related areas are Food Biotechnology and Food Biophysical Chemistry.

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
