“…However, field instruments based on more complex analytical techniques have also been described. These include photometry [1], voltammetry [2], flow-injection analysis [3] and X-ray fluorescence [4,5]. Moreover, portable instruments based on the separation methods of gas chromatography (GC) [6], high-performance liquid-chromatography (HPLC) [7] and ion chromatography (IC) [8,9] have also been reported.…”

A new portable capillary electrophoresis instrument with capacitively coupled contactless conductivity detection was developed and optimized for the sensitive field measurements of ionic compounds in environmental samples. It is powered by batteries and the high voltage modules are capable of delivering up to 15 kV at either polarity for more than one working day. Inorganic cations and anions, including ions of heavy metals and arsenate, could be determined with detection limits in the range from about 0.2 to 1 mM. The instrument was field tested in a remote region of Tasmania and nitrite and ammonium could be determined on-site at concentrations as low as 10 ppb in presence of other common inorganic ions at concentrations which were 2 to 3 orders of magnitude higher.

“…As a technique for determining the existence of elements, X-ray fluorescence (XRF) spectrometry has been widely used in scientific researches and engineering fields [21][22][23][24]. XRF spectrometry can be divided into wavelength-dispersive XRF (WD-XRF) and energy-dispersive XRF (ED-XRF).…”

Nine gemstone samples were analysed by using a portable X-ray fluorescence-X-ray diffraction (XRF-XRD) system without any destructive preparation processes. The samples were measured by groups based on the transparency and the complexity of molecular structure. The XRF and the XRD measurements for each sample were performed simultaneously.The key experimental parameters were optimized in order to obtain XRD patterns acceptable for phase identification in a limited time. The XRF spectrum of each sample was analysed first to acquire the elemental composition qualitatively, and the information was then applied to refining possible phases. The phase analysis process of each sample was described in detail and the most likely phases were determined. Normal XRD experiments were conducted in order to verify the results. Advantages, disadvantages and applicable range of the system were analysed. The results indicate that the portable XRF-XRD system can be applied to identifying particular gemstones effectively, while single-crystal gems may not be identified very well. Wider recognition and application of the portable XRF-XRD system in cultural heritage and gemological fields call for hardware development, software updating and more real application cases.

“…Many models can be used to extract quantitative results from XRF spectra, nevertheless all of them are ascribable to two main families: [26][27][28][29][30] the fundamental parameter model (FP), that implies the complete knowledge of all variables describing the experimental condition, and the influence coefficient model (IC), that requires a series of standard materials.…”
