Determination of Trace Elemental Composition of CaCO3: Application to Mass Limited Abiogenic and Biogenic Carbonates

Geochemistry, Geophysics, Geosystems
An improved method for accurate and precise determination of metal to calcium ratio in mass limited calcium carbonate samples has been developed. We used an Agilent®5800 ICP‐OES for major element (Na/Mg/Sr to Ca) and an Agilent®8900 ICP‐QQQ‐MS for minor ...

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

Advanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

CONTROL CHART FOR STABILITY ANALYSIS OF PROCESS IN ICP-OES

, 2022
The statistical process control in an analytical chemistry laboratory allows providing reliable results and assists in decision making at various strategic levels. The most important tool, especially in the analysis of ICP-OES is the control chart, in which the results should be randomized within specified limits, allowing demonstrate that the ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Elemental determination of lubricating grease using ICP-OES [PDF]

, 2021
The focus of most lubricating grease testing has been based on performance and appearance rather than determining the concentration of chemical components. The primary reason being lubricating grease is a difficult matrix to work with from the perspective of the analytical laboratory.

ROS Self‐Supply Nanoplatform Based on Fenton Catalyst for Chemodynamic and Immunotherapy: Reprogramming Cold Tumor Into Hot Tumor in Cancer Treatment

Advanced Science, EarlyView.
A multifunctional HA‐conjugated nanoplatform (HA‐PGMC) integrates CuO2, glucose oxidase, and mil‐100 to enable cascade catalytic ROS generation in tumor microenvironments. This self‐supplying ROS strategy induces immunogenic cell death, reprograms “cold” tumors into “hot” ones, and synergizes with PD‐L1 blockade, achieving potent chemodynamic ...

Determination of Rare Earth Oxides in Bauxite by Inductively Coupled Plasma-Optical Emission Spectrometry

Yankuang ceshi, 2020
BACKGROUND When the rare earth oxides in bauxite are determined by inductively coupled plasma-optical emission spectrometry (ICP-OES), acid dissolution often results in incomplete dissolution of samples, and a large amount of fluxes at high temperature ...
