“…More recently, Harrison and Rapsomanikis edited a book [205] dedicated to atomic spectroscopy interfaced with Chromatographie systems (GC, HPLC, SFC) for environmental analysis. Other reviews have been written [59,[206][207][208][209] includ ing ones on sample introduction techniques [210,211]. In addition, LaFreniere et al [212] have described the ideal characteristics of on-line element specific detectors.…”

“…Inductively coupled plasma mass spectrometry (ICP‐MS) is one of the most frequently used techniques to analyze (trace) metal concentrations in various fields and sample matrices. In most applications, the sample is introduced into the ICP‐MS system in the dissolved state, using a common nebulizer/spray chamber setup 1,2 . However, these approaches can be modified enabling direct solid sample introduction.…”

Rationale (Eco‐)toxicological effects are mostly derived empirically and are not correlated with metal uptake. Furthermore, if the metal content is determined, mostly bulk analysis of the whole organism population is conducted; thus, biological variability is completely disregarded, and this may lead to misleading results. To overcome this issue, we compared two different solid sampling techniques for the analysis of single organisms. Methods In this study, complementary electrothermal vaporization/inductively coupled plasma mass spectrometry (ETV/ICP‐MS) ⇔ laser ablation/inductively coupled plasma mass spectrometry (LA/ICP‐MS)‐based methods for the analysis of individual organisms were developed and the results obtained were compared with the concentrations obtained after digestion and measured using ICP‐MS. For this purpose, a common (eco‐)toxicological test organism, the mud shrimp Corophium volutator, was selected. As proof‐of‐concept application, these organisms were incubated with environmentally relevant metals from galvanic anodes, which are often used for protection against metal corrosion in, for example, offshore wind farms. Results The bulk analysis revealed that large quantities of the incubated elements were detectable. Using the ETV/ICP‐MS method, we could identify a high biovariability within the population of organisms tested. Using the LA/ICP‐MS method, it could be determined that the large quantities of the elements detected were due to adsorption of the metals and not due to uptake, which correlates well with the absence of (eco‐)toxicological effects. Conclusions The results obtained imply the efficiency of complementary methods to explain the absence or presence of (eco‐)toxicological effects. In particular, methods that allow for single‐organism analysis or provide even a spatial resolution support the interpretation of ecotoxicological findings.

“…[8][9][10] Whilst there have been many advances in nebuliser technology to overcome this (particularly at low ow rates) the spray chambers used are largely unchanged. It has long been recognised that sample transport efficiency to the plasma is a limiting factor of Inductive Coupled Plasma (ICP) based analyses.…”

The development of low cost 3D printer technology is having a profound effect on everyday life. Over the past few years there have been many reports in the media detailing futuristic uses of this technology. Whilst the merits of these applications are clear there is an opportunity for this technology to enhance current research where a degree of fabrication is required. This work describes some initial research into the use of 3D printing for the fabrication of cyclonic spray chambers for inductively coupled plasma applications. The linearity, precision and detection limits obtained from the 3D printed chamber have been compared to a commercial model with largely positive results. Comparison between the performance of subsequent prints of the same spray chamber has also been carried out and has been shown to be highly reproducible. This work suggests that lowcost 3D printing techniques can be used as an inexpensive way to fabricate prototype spray chambers to accelerate the research in this area.
