“…2 -4 In the latter application the material to be analysed is typically a solid sample, although it is worth mentioning that increasing interest also exists for analysing samples in the liquid or gas phase. 5 The glow discharge plasma is created by applying a potential difference between two electrodes that are placed in a cell (or they form the cell walls) filled with a gas. For analytical applications, argon is the most commonly used discharge gas at a pressure in the range 50-500 Pa.…”

We have developed a comprehensive modelling network for glow discharge plasmas used for analytical spectroscopy in order to obtain better insight into the plasma characteristics that are desirable for good analytical practice. The modelling network consists of Monte-Carlo, fluid and collisional-radiative models, as well as a heat transfer model and a computational fluid dynamics code, to describe the behaviour of the various plasma species. Typical calculation results include the electrical characteristics (current, voltage, pressure relations), the electric field distribution, the densities, fluxes and energies of the various plasma species, information about the various collisions in the plasma and about cathode sputtering, optical emission intensities, etc. In this paper we focus on results that are of direct analytical interest, such as crater profiles and erosion rates due to sputtering, implantation profiles, glow discharge source design, optical emission intensities and the effect of hydrogen addition.

“…The advent of furnace-based atomization in the 1960s made the application of the later even more prevalent. The 1970s were considered the decade of the inductively coupled plasma atomic emission spectroscopy (ICP-AES) where the technique was refined and many commercial instruments were developed [50]. Inductively coupled plasma mass spectrometry (IPC-MS) was developed in the 1980s and along with ICP-AES has since become one of the most commonly used methods for trace analysis because of their low limit of detection (LOD), high sensitivity, precision and analytical throughput [51].…”

The applications of gold nanoparticles (AuNPs) in biomedicine span the imaging, diagnosis and therapy domains. Current methods of nanoparticle quantification are based on inductively coupled plasmas (ICP) methods, which are heavily influenced by sample preparation. This becomes challenging when quantifying trace-level amount of AuNPs in the presence of organic matrix. In this thesis, total reflection X-ray fluorescence (TXRF) spectrometry is proposed for quantifying cellular uptake of AuNPs in MDA-MB-231 breast cancer cell line suspensions. The most suitable internal standard and fitting approach that yield 90-110% recovery rate along with different sample preparation methods were investigated. Reference material AuNPs were used to validate the quantification capabilities of the newly developed method. Direct comparison of TXRF and ICP-AES showed ability of TXRF to accurately quantify nanoparticle uptake while further demonstrating the importance of sample preparation for ICP-AES. These results suggest that TXRF has potential for quantifying nanoparticle uptake and their kinetics.

“…Among them, inductively coupled plasma mass spectroscopy (ICP-MS) has the advantages of simultaneous multi-elemental analysis and extremely sensitive detection for charged analyte species. [3][4][5] While combining with an on-line preconcentration system, 6-8 the ICP-MS may further enhance its detection sensitivity. Although ion-exchange resins have usually been adopted for matrix separation and sample preconcentration in aqueous solution, [9][10][11][12] in this work we focused on the liquid-solid sorbent extraction method as an alternative, and employed a desolvation system to improve the operation efficiency.…”

Inductively coupled plasma-mass spectrometry (ICP-MS) incorporated with an on-line preconcentration system was used to determine trace amounts of ten metals including Ni, Cu, Zn, Rh, Ag, Cd, In, Au, Tl, and Pb in aqueous solutions and seawater. These metals, which formed the complexes, were retained in a sorbent microcolumn, followed by elution with methanol through a desolvation unit, which was capable of removing 83% of methanol. The limits of detection for these elements were determined simultaneously to be in the range from 3 to 20 ng/L.
