“…Significant improvements of the LODs of the trace elements can be implemented by the use of the ETV for the sample introducing into the ICP. [10][11][12][13][14][15] ETV is a powerful and high effective method of sample introduction into the ICP during ICP-MS or ICP-OES analysis. [16][17] During ETV the sample is evaporated from the resistively heated substrate.…”

High purity molybdenum and its compounds are used for the synthesis of ionizing radiation detectors for search for dark matter and double beta decay. Properties of these detectors largely depend on their trace composition. The new mass-spectrometry with inductively coupled plasma (ICP-MS) and electrothermal vaporization (ETV) method was developed for the analysis of high-purity molybdenum. The samples were introduced into the ICP using the ETV device. The vaporization curves of matrix element (molybdenum) and trace elements were studied in detail. The dependence of analytical signal and limits of detection (LODs) of analytes versus ETV-ICP-MS instrumental parameters (ICP power, transport flow, ion optics settings) was established. The proposed method of ETV-ICP-MS analysis allowed us to control the content of 28 trace elements in high-purity molybdenum with a purity of 6N (99.9999% wt.) and provided LODs from 0.3 to 200 ng g-1. Using of ETV for ICP-MS analysis of molybdenum led to decreasing of the LODs of trace elements from 3 to 200 times comparing with ICP-MS analysis with standard sample introduction system. The validation of proposed ETV-ICP-MS method was performed by spike experiment and by comparing the results of ETV-ICP-MS, ICP-MS, and atomic absorption spectrometry with electrothermal vaporization (GFAAS) analysis.

“…2 ETV-ICPMS can also aid in mitigating spectroscopic and non-spectroscopic interference by separating analyte elements from the matrix through judicious use of the furnace temperature program and chemical modification. 3 Alternatively, LA-ICPMS uses a pulse of high-irradiance laser energy focused on a sample surface to generate fine particles that are then transported into the ICP. LA is unique as it offers lateral resolution down to ~ 5 µm and a depth resolution down to < 1 µm.…”

A novel sampling probe composed of a coaxial-tube that functions at a continuous-flow was used to inject 1 μL of sample into an inductively coupled plasma mass spectrometer. Simply touching a sample to the dome of liquid at the inlet of the liquid microjunction (LMJ) allows for sample introduction into a flowing carrier stream that transports sample into the plasma-similar to the mechanism of sample transport in flow injection analysis. This self-cleaning sampling system, allows for sampling of minute amounts of liquids at atmospheric pressure as well as leaching of soluble components off the surface of a solid. Preliminary results demonstrate the implementation of this probe in steady-state, flow injection, and surface sampling modes. A substantial reduction of matrix effects and oxide interferences resulted with 1 μL injections. In fact, the performance of LMJ with 1 μL injections in terms of spectroscopic and non-spectroscopic interference mitigation, sensitivity and detection limit is very similar to that previously reported with 1 μL mono-segmented flow analysis.

This article provides an overview about state‐of‐the‐art methods in the field of plasma spectrometry and its application in material science. Different types of plasmas with their special characteristics for various applications are described. Indirect analytical methods involving sample digestion and often also analyte/matrix separation prior to analyzing the samples still represent the most important routine methods. Here, plasma optical emission and mass spectrometry are the most frequently used determination techniques with a wide variety of instruments commercially available. To avoid the risk of analyte loss or of contaminations during an often time consuming and laborious sample preparation, the use of techniques with direct solid sampling is considered an attractive alternative for the analysis of many materials. A survey on applications with a special focus on direct solid sampling techniques such as GDMS, GD‐OES, LA‐ICPMS, ETV‐ICPMS, ETV‐ICP‐OES, DC‐Arc is given. Different possible calibration strategies are discussed.
