Summary: Chemical vapor or hydride generation (CVG/HG) still plays a significant role in continuous flow sample introduction system. The development of new commercial CVG/HG accessories has improved the analytical possibilities for determination of hydride forming analytes. Despite the availability of alternatives, these systems are still widely applied. The commercialization of MIP OES has also contributed to the popularity of these solutions. The review discusses the latest achievements in generators and instruments, as well as new strategies in sample preparation.

Summary: The developed method utilizes a miniaturized dielectric barrier discharge microplasma atomic emission spectrometer coupled with a tungsten coil (W-coil) for on-line hydride generation trapping-electrothermal vaporization, resulting in fast, low-cost, and sensitive determination of trace cadmium. By adopting a horizontally fixed W-coil and flow injection mode, the total sample throughput can be greatly improved.

Summary: A fast screening multi-element analysis method was developed to investigate the concentrations of potentially toxic and essential elements in natural toothbrush known as miswak. The study found significant differences in concentration of elements like As, Cd, Fe, Mg, Mn, Mo, Pb, and Se between thin and thick miswak, indicating accumulation of these elements as miswak grows. Peeling off the surface layer of miswak removed a significant portion of potentially toxic elements.

Summary: This study uses off-the-shelf infrared heaters to heat the sample introduction system on a Varian 820MS instrument, resulting in improved sensitivities and detection limits. The infrared heating increases sensitivities by a factor of 2 to 16 and improves detection limits by a factor of 1.1 to 3.5 for most analytes. It also reduces the formation of doubly charged species. The infrared heating also enhances plasma robustness.

Summary: The combination of two-jet arc plasma optical emission spectrometry (TJP-OES) and electrothermal vaporization (ETV) for sample introduction has been proposed for the direct analysis of solid tellurium samples. The separate vaporization of the sample matrix and analytes by ETV-TJP-OES reduced interference and allowed for lower limits of detection. The technique demonstrated simultaneous determination of up to 17 elements in high-purity tellurium samples with greatly improved LODs compared to traditional ICP OES methods.

Summary: This study investigated two green and homogeneous enhancement systems for CVG of tungsten, including photochemical vapor generation (PVG) and hydride generation (HG) with sensitizers Fe3+ and DDTC, respectively. The PVG and HG under optimal conditions achieved limits of detection (LODs) of 0.02 mu g L-1 and 0.003 mu g L-1, respectively. The mechanisms of enhancement were found to involve various chemical species and reactions in the PVG process, as well as potential complexation between W(VI) and DDTC in the HG process. This work expands the element scope of CVG and provides insights into potential sensitizers for enhancing the efficiency of CVGs in the future.

Summary: The use of cricket powder to enhance the nutritional value of biscuits showed promising results, although higher levels of enhancement may not be accepted by consumers. This small change in recipe significantly increased protein content and other essential nutrients, making the biscuits more nutritious. Cricket powder-augmented biscuits, along with other functionally enhanced food products, offer a potential solution to meet future human food demands.
