Hyperspectral imaging is currently a very well-known and much used technology for measuring features in different fields, such as chemistry, geology, medicine, food and agriculture, either spaceborne (satellites), airborne (drones) or at close proximity (e.g. field scanning, industrial sorting lines or microscopy). Its background is two-fold, and it can be considered as a special case of spectroscopy (“imaging spectroscopy”) or a special case of imaging (“spectral imaging”). Current practice is to use adjectives such as multi and hyper added to “spectral imaging” in order to characterise the number of wavelength bands. In this paper we propose the community to use scientifically sound terminology, like “imaging spectroscopy” or “spectral imaging”, without using ambiguous adjectives. Further, we encourage the community to define and agree upon clear adjectives to describe the number of variables in the naming of our imaging technique.

Tony Davies, Peter Lampen and Robert Lancashire are worried about their metadata, or perhaps the lack of it. With the explosion of data and ways to mine and make use of it, having accurate and appropriate metadata about analytical data sets is vital if they are to be reused efficiently or at all. This is also an area that is being increasingly targeted by regulators, with the US FDA issuing guidance at the end of 2018; others will follow. You have been warned.

This column concludes the first series of Sampling Columns. More will appear in a sequel series, mainly aimed at presenting practical examples, case histories, demonstrations—all of which will assume that the value of only practicing representative sampling has been fully acknowledged and the relevant know how has been comprehended. Here, we end the first educational exposé of the Theory of Sampling (TOS) by focusing on the current state of awareness and with an acknowledgement of the need to involve TOS in all relevant international scientific fora, in technology, industry and in the commercial marketplace.

Introduction Surfaces play a crucial role in a wide range of applications, hence have been the subject of intense study since the very early days of chemical analysis. With increasing knowledge and manufacturing capabilities, the need for ever more detailed surface analytical information has grown rapidly over the years. Whilst vibrational spectroscopies, in particular, have yielded crucial information in a wide range of settings, the very nature of these techniques does limit the information available. Mass spectrometry on the other hand has the capability to yield exquisitely detailed datasets, but has traditionally been significantly less convenient in actual applications. After initial use, predominantly for inorganic and materials science applications and with Alfred Benninghoven (Germany) and David Briggs (UK) among the main protagonists, advances in liquid metal ion guns and time-offlight analysers enabled secondary ion mass spectrometry (SIMS) to become a powerful technique for the analysis of organic materials. A step-change in sensitivity revolutionised the use of SIMS in the latter part of the last century and allowed researchers to acquire detailed mass spectra from damageprone organic materials without significantly altering the surface chemistry under investigation. Moreover, surface mass spectra containing information on large molecules can be generated from very small surface areas, especially since the introduction of cluster primary ion sources, allowing micron-scale image generation with an enormous wealth of information, in the form of a high mass-range and -resolution spectrum for each image pixel. These developments opened up entire new fields of analysis and time-of-flight SIMS (ToF-SIMS) has since been applied highly successfully in a seemingly endless range of applications from medical implants and cell biology to astrochemistry, art history and archaeology.1 Whilst much exquisite research has been and continues to be published using SIMS, a crucial restriction is the requirement for samples to be in a vacuum environment. This necessitates samples sensitive to vacuum to be especially prepared to negate any adverse effects. Moreover, sample throughput is restricted by pump-down times and sample size and geometry are limited to
