Quality Assurance and Testing Spectrometric Analysis Lead quality control relies on ppm-level impurity analysis via optical emission spectrometry (OES), X-ray fluorescence (XRF), and inductively coupled plasma (ICP): OES: 2-3 minutes per sample; detection 1-10 ppm; routine QC and final certification. XRF: 1-2 minutes; detection 5-20 ppm; rapid ...
Rare earth elements (REEs) are often a target of rapid analysis in geology, mining, and processing: the goal is to quickly determine whether enrichment is present, how composition changes across zones, and which streams or lots look promising. XRF (X-ray fluorescence) is well suited for these tasks, but when working with REEs it is important to understand the method’s limitations. In ...
In modern electronics manufacturing, precise control of solder alloy composition is critical for assembly quality and reliability. Electronic manufacturing services (EMS) and surface-mount technology (SMT) lines consume kilograms of tin-based solders every day—both lead-free alloys (e.g., Sn-Ag-Cu or Sn-Bi) and classic tin-lead (Sn-Pb) for specialized tasks. Even small deviations in ...
The GB/T 30835 standard specifies the use of microwave digestion combined with inductively coupled plasma optical emission spectrometry (ICP-OES) for lithium measurement. Microwave digestion offers rapid sample decomposition in sealed vessels with benefits including low blank values, high parallelism, and convenient ...
The first two methods can analyze a single element, and the operation is complicated, time-consuming and laborious, and the efficiency is low; photoelectric direct reading spectrometry can analyze multiple elements at the same time, and the operation is easy, but it can only analyze block samples. ICP-OES has the advantages of high sensitivity, fast analysis ...
Nesvax Innovations Limited, a leading provider of laboratory and analytical solutions, is pleased to announce the successful installation of Analytik Jena’s Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) system at Yana Oils Limited, a prominent petroleum company based in Nairobi, Kenya. ...
FPI Solution: In the above application scenario, FPI’s self-developed EXPEC-6000 series inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) can be used to measure and analyze the content of Ba, Cd, Cu, Ni, Zn and other elements in the lixivium of solid waste to meet the standard the requirements of relative regulations. ...
Ions – we encounter these tiny charge carriers constantly. Depending on the concentration of certain anions (negative ions) and cations (positive ions), they can have a significant impact on humans and the environment. Thanks to ongoing quality control in several industries such as food and beverage, the metallurgical industry, and water management, defined limits are neither exceeded nor ...

What is a high-matrix sample? A high-matrix sample usually has a high percentage of dissolved solids. These are referred to as "totally dissolved solids" (TDS) and are present in high-matrix samples in a concentration of 3 to 30 percent. Volatile organic compound (VOC) solutions, such as petrochemicals or fuels, also count as high matrix samples. These solids and organic solutions can cause ...
From Mining to High-Purity Metals: Efficient Ways for Elemental Analysis In terms of elemental analysis, the mining value chain has vastly different requirements. During early exploration and exploitation mostly major contents of elements in raw materials need to be determined. In later process stages – for example during production of high-purity metals and alloys – trace and ...
Abstract In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using Merck water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated. Key words or phrases Trace elements, ...
Analytical laboratories confront a wide range of issues that can affect their data, such as resources, trained personnel, time constraints and traceability. New dilution and sample introduction accessory systems have been engineered to confront these issues. With these systems it is common to see calibration coefficients of > 0.999, serial dilutions with a precision of < 3% and an accuracy ...
Laser ablation is a powerful approach to chemical analysis because of its versatility. It has advantages in chemical analysis including direct characterization of solids, no chemical procedure of dissolution, which reduces the risk of contamination or sample loss, analysis of very small samples not separable from solution analysis, and determination of spatial distribution of elemental ...
Data quality was evaluated by intercomparison with 24-h PM10 filter data analysed with ICP-OES for major elements, ICP-MS for trace elements, and gold amalgamation atomic absorption spectrometry for Hg. 10 20 elements (S, K, Ca, Ti, Mn, Fe, Cu, Zn, Ba, Pb) showed an excellent correlation between the compared methods, with r2 values ≥ 0.95, ...

The laboratory employs and combines diverse techniques such as chromatography (LC, GC, SEC/GPC, IC), mass spectrometry (LC/MS, GC/MS, MALDI-ToF,ToF-SIMS, ICP/MS), failure analysis, thermal analysis, rheology and spectroscopy (NMR, FTIR, Raman, NIR, ICP-OES, XRF, XPS) to analyze polymers, catalysts, surfactants, ceramics, nanomaterials, ...
Chromium in roots and shoots was determined by ICP-OES. It was observed that all plant species have the ability to remove both Cr3+ and Cr6+ from the aqueous solution for the specified initial concentration. ...
In this study, the concentrations of heavy metals Pb, Cu, Zn, Cd, Ni, Fe, Mn and Cr were determined using an inductively coupled plasma and optical emission spectrophotometer (ICP-OES), and water quality parameters pH, temperature, and conductivity were measured using the YSI 556 MPS water probe. ...
