“…These days, inductively coupled plasma mass spectrometry (ICP-MS) is the most popular approach for elemental analysis in various kinds of samples including chemical, material, environmental, biological, clinical, food, beverage, and so on, [1][2][3] which could be attributed to the merits of ICP-MS for simultaneous multi-element analysis, wide linearity range, highly sensitive measurements, and better selectivity than that provided by optical analysis. On the other hand, the development of novel ICP-MS instruments has slowed down in recent years, 4 which could be partly attributed to the fact that the line-up of instruments produced by various producers have provided enough selections for users.…”

The standard addition method (SAM) based on gravimetric sample preparation was investigated as an approach for the removal or cancelling of matrix effects in measurements by inductively coupled plasma mass spectrometry (ICP-MS). Deduction of the equations and experimental confirmation of the method are both given in the present work. After measuring both spiked and non-spiked samples by ICP-MS, the concentration of an element could be calculated based on the signal intensity ratio to an internal standard. A practical example was provided for the measurement of Fe in a certified reference material (CRM), i.e. NMIJ CRM 7512-a (milk powder). The validity of the method had been confirmed by the results of international comparisons with various kinds of matrix, including bioethanol, human serum, biodiesel fuel, drinking water, infant formula milk power, and seafood. The suggested method had been applied to measurements of multiple elements in three CRMs, including tap water, milk powder, and tea leave powder, respectively.

“…Laser-induced breakdown spectroscopy (LIBS) has been demonstrated as a powerful elemental analysis technique on substances due to its multi-element analysis, high sensitivity and real-time process [ 7 , 8 ]. It allows fast contact-less analysis of any material and has unique versatility and capabilities for real-time composition determination [ 9 , 10 ]. At present, LIBS plays an important role in the detection of human tissues [ 11 ].…”

The fast and reliable analysis of electrolytes such as K, Na, Ca in human blood serum has become an indispensable tool for diagnosing and preventing diseases. Laser-induced breakdown spectroscopy (LIBS) has been demonstrated as a powerful analytical technique on elements. To apply LIBS to the quantitative analysis of electrolyte elements in real time, a self-developed portable laser was used to measure blood serum samples supported by glass slides and filter paper in this work. The partial least squares regression (PLSR) method was employed for predicting the concentrations of K, Na, Ca from serum LIBS spectra. Great prediction accuracies with excellent linearity were obtained for the serum samples, both on glass slides and filter paper. For blood serum on glass slides, the prediction accuracies for K, Na, Ca were 1.45%, 0.61% and 3.80%. Moreover, for blood serum on filter paper, the corresponding prediction accuracies were 7.47%, 1.56% and 0.52%. The results show that LIBS using a portable laser with the assistance of PLSR can be used for accurate quantitative analysis of elements in blood serum in real time. This work reveals that the handheld LIBS instruments will be an excellent tool for real-time clinical practice.

“…The lack of suitable reference materials in the NORM industries is a significant issue [2,[7][8][9][10][11][12], which also makes initial validation of procedures challenging. Candidate reference soil and sediment materials from British Geological Survey (BGS) were digested using lithium borate fusion and the concentration of 232 Th and 238 U calculated and compared with the reference values as an initial validation of the method.…”

“…Additionally, the accurate characterisation of radionuclides is reliant on measurement of certified reference materials (CRM) that ensure quality control and metrological traceability through method validation and calibration of instruments [7]. Owing to the wide range of sample types across industrial sectors, the current lack of CRM is a significant constraint [2,[7][8][9][10][11][12].…”

Accurate measurement of natural and anthropogenic radionuclide concentrations is of critical importance to end users in the nuclear sector to ensure correct classification prior to storage, recycling, reprocessing or disposal. Uncertainties in the characterisation of solid matrices and materials could lead to safety, quality and financial implications. Robust sample preparation methods are vital, in particular effective sample digestion, as under-estimated chemical yield recovery results in a corresponding under-estimation of activity levels. Borate fusion has been proven to effectively digest a range of complex sample matrices in the geosciences but is not used routinely elsewhere. In this study, we describe an automated procedure for borate fusion of multiple matrices encountered in nuclear decommissioning, containing diverse radionuclides over a range of activity concentrations. The impact of digestion flux, sample mass and sample to flux ratios are described, as well as the subsequent separation and measurement techniques. The results contribute to accurate and precise measurement of radionuclides in various matrices, as well as to characterisation of reference materials, providing greater confidence in nuclear industry programmes worldwide.
