“…[13][14][15] In case of the use of portable LIBS and EDXRF systems, the most common in situ applications involve the determination of potentially toxic metals in soil, [16][17][18][19] and analysis of samples as diverse as those of industrial, geological, archaeological and of cultural heritage interest. 18,[20][21][22][23][24][25] The appropriate analytical performance exhibited by commercially available portable XRF instruments have been recently demonstrated elsewhere 5,26 and certainly contributed to spark the interest of researchers in the proposition of in situ methods using such a mobile instrumentation. Particularly, the use of portable XRF (PXRF) systems in the determination of macro-and micronutrients in plant materials has received increased attention by the scientific community.…”

A portable energy dispersive X-ray fluorescence spectrometer was evaluated in the in situ analysis of fresh sugar cane leaves for real time plant nutrition diagnosis. Fresh leaf fragments (n = 10 sugar cane varieties; 20 fragments per leaf; 2 measurement sites per fragment) were irradiated and the averaged data from X-ray characteristic emission lines intensities (for K, Ca, S and Si Kα lines) were in close agreement with mass fraction data obtained by a validated comparative method. The linear correlation coefficients (r) ranged from 0.9575 for Ca to 0.9851 for Si. The obtained limits of detection were at least two-fold lower than the critical nutrient levels. Manganese can also be properly determined, but validation still requires more robust calibration models. The proposed method is a straightforward approach towards the fast evaluation of the nutritional profile of plants avoiding time-consuming steps, which involve drying, grinding, weighing, and acid digestion.Keywords: in situ analysis, portable X-ray fluorescence spectrometry, plant mineral analysis, sugar cane, silicon IntroductionPlant nutrition diagnosis is a well-established and reliable way for guiding the proper fertilizer recommendation contributing to the healthy growing of crops of economic importance.1 The analytical protocol most frequently applied for the determination of macro-and micronutrients in plant materials often requires an a priori test sample decomposition, usually performed by microwave-assisted acid sample dissolution, followed by determination using inductively coupled plasma optical emission spectrometry (ICP OES). 2Some studies have focused on the use of the direct solid sampling analysis based on X-ray fluorescence spectrometry (XRF), [3][4][5] laser-induced breakdown spectroscopy (LIBS) [6][7][8] or laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) 9-11 for assessing the mineral nutrition profile of plants. The most common way of sample presentation by using the aforementioned direct analysis methods involves the interrogation of a previously ground plant material in a pellet form.6,9 A promising trend of research is the direct analysis of the dried plant leaf without the need for grinding or pelletizing steps.12 On this subject, both LIBS and energy dispersive XRF (EDXRF) have been used.The increasing advances in the field of portable instrumentation has expanded the application of this emerging technology. Such a fast development is due to improvements in digital electronics and in the development of miniaturized sensors and other crucial components. These novel mobile equipment offer a plethora of advantages to the analyst such as real time and onsite determinations of organic and inorganic analytes in a myriad of sample matrices. [13][14][15] In case of the use of portable LIBS and EDXRF systems, the most common Guerra et al. 1087 Vol. 29, No. 5, 2018 in situ applications involve the determination of potentially toxic metals in soil, [16][17][18][19] and analysis of samples as diverse as those o...

“…The use and applications for XRF have been reviewed in numerous books and journal papers, including the extensive annual reviews in the Journal of Analytical Atomic Spectrometry (West et al . , , ). A recent book (Croudace and Rothwell ) discussed the use of micro‐XRF for analysing sediment cores, covering the history, its applications and the technical issues related to its use.…”

This GGR biennial critical review covers developments and innovations in key analytical methods published since January 2014, relevant to the chemical, isotopic and crystallographic characterisation of geological and environmental materials. In nine selected analytical fields, publications considered to be of wide significance are summarised, background information is provided and their importance evaluated. In addition to instrumental technologies, this review also presents a summary of new developments in the preparation and characterisation of rock, microanalytical and isotopic reference materials, including a précis of recent changes and revisions to ISO guidelines for reference material characterisation and reporting. Selected reports are provided of isotope ratio analyses by both solution-nebulisation MC-ICP-MS and laser ablation-ICP-MS, as well as of radioactive isotope geochronology by LA-ICP-MS. Most of the analytical techniques elaborated continue to provide new applications for geochemical analysis, however it is noted that instrumental neutron activation analysis has become less popular in recent years, mostly due to the reduced availability of nuclear reactors to act as a neutron source. Many of the newer applications reported here provide analysis at increasingly finer resolution. Examples include atom probe tomography, a very sensitive method providing atomic scale information, nanoscale SIMS, for isotopic imaging of geological and biological samples, and micro-XRF, which has a spatial resolution many orders of magnitude smaller than conventional XRF

“…5 Although notionally restricted to XRF techniques, the review does also include a variety of other techniques, such as EXAFS and XANES, as researchers oen conduct multiple experiments at the same facility to maximize the amount of information that is collected in the time allocated. The researchers have, therefore, booked time on an appropriate beamline and then taken the samples to an appropriate facility.…”
