Published under a Creative Commons BY-NC-ND licence The world community of sampling has reasons to celebrate. The 10th World Conference on Sampling and Blending (WCSB10) took place between 31 May and 2 June 2022 in Kristiansand, Norway. It was the first physical gathering of members of the international sampling community in 2.5 years. A total of 121 in-person attendees from 20 nations together with 19 online attendees who, for one reason or other, could not travel to Norway. In the summer of 2021 when prospects for in-person gatherings of this magnitude were distinctly bleak, the organisational committee nevertheless made a deliberate decision to prepare for success and to go all out for an in-person conference. As it turned out, this paid off beautifully; a total attendance of 140 is right on par with several earlier conferences. From many personal reactions and statements, it was clear that the international sampling community had been starved of physical interaction. Again and again, delegates declared their excited satisfaction over simply being together again and being able to freely interact vis-à-vis one-another—to the delight of the scientific and organising committees.

Introduction In the last article,1 we concentrated on how the “screwdriver in the spectroscopist toolkit” the UV/ visible spectro(photo)meter, and its associated software has evolved during our Four Generations. In this article we’ll now look at three other related spectroscopic techniques/tools in the box, namely, Fluorescence, near infrared (NIR) and Raman; and discuss the “what”, “where” and “how” of these techniques are being used to improve the quality of the measurement processes associated with them. This article, therefore, uses the Four Generations in the previously described time periods and does uncover some interesting points for discussion. This chronology effectively plots the evolution of these techniques from Research to Analytical Quality Assurance (QA), and the associated Quality requirements associated with them. However, with due deference to the multitude of reference texts available, let’s quickly state that it is not the intention of this article to discuss the theory of the appropriate science, and if this is of interest to the reader, then any of the excellent, and well-known texts, some of which are referenced below, should be consulted.

The hippocampus (Figure 1A) is a brain region critical to spatial learning and memory. The hippocampal formation contains a highly organised architecture of neurons and neuron–neuron connections, which have been intensively studied by neuroscientists for many decades. In fact, the hippocampus is often referred to as the “Rosetta Stone” of neuroscience, with many believing elucidation of hippocampus circuitry and cell function will unravel the inner workings of the brain. A fasc inat ing fact of the hippocampus is that it appears to be relatively enriched in transition metal ions, particularly Fe, Cu and Zn (Figure 1B). The Zn enrichment was discovered by scientists developing histochemical methods to detect labile metals in brain tissue (e.g., works of Danscher and others),1,2 with work led by Frederickson definitively demonstrating that the characteristic pool of labile metal ions observed in the hippocampus was Zn.2–4 Of great interest, experiments aimed at depleting the labile Zn pool in the hippocampus subsequently revealed behavioural and cognitive deficits in mice,2 consistent with facets of memory loss observed during neurodegenerative diseases of ageing, such as Alzheimer’s disease.5 Consequently, a plethora of lines of research enquiries emerged, aiming to uncover the physiological and chemical pathways through which transition metal ions might be implicated in healthy memory function, and also memory loss. While the classical Timm’s histochemical stain has been invaluable to study labile Zn in the hippocampus (and brain in general), a number of important advances in this field have now been made using direct spectroscopic mapping. Specifically, the provision of intense (bright) and tuneable X-ray sources at synchrotron facilities has revolutionised the biological applications of X-ray techniques, especially X-ray fluorescence spectroscopy (XRF) and X-ray absorption spectroscopy (XAS). Key advantages of XRF are its ability to simultaneously and directly detect (map) elemental distribution at cellular resolution (and sometimes sub-cellular resolution), in situ. The direct in situ detection capabilities of XRF are
