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 screening and ...
In this study, we follow the pharmacopoeia guidelines and apply microwave digestion for sample preparation, combined with ICP-MS (inductively coupled plasma mass spectrometry) for the determination of heavy and toxic elements in American ginseng. ...
In the cement industry, x-ray fluorescence analysis (XRF) is one of the major techniques employed for raw material and final product quality control. Typically, "pressed pellet" sample preparation is used; however, the disadvantage to this is that this technique shows only relative data to known and accepted reference methods like fusion or wet chemistry and takes no account of the different ...
Sample handling Mineral water samples were stabilized with nitric acid and filtered through a 0.45 μm water system filter head for measurement on the machine. ...
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 ...
Easier sample prep and fast analysis means that if throughput is your main requirement, MC-ICP-MS is likely to be on top of your list. And aside from the easier sample prep, MC-ICP-MS as a technique can be used for more elements than a TIMS – enhancing its flexibility. ...
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 ...
In inductively coupled plasma–mass spectrometry (ICP-MS), the chromium (52Cr) signal can be affected by interference from the recombination of background plasma 40Ar and sample-specific matrix 12C. ...
These criteria, detailed in USP/, recommend analysis of drug products for element impurities by either ICP-AES or ICP-MS. Laboratories must measure impurities based on a J value for each drug product; drug products may be oral, parenteral (ex. intravenous, injection), or inhalation types. ...
Laser ablation is a process in which a laser beam is used to remove a portion of mass from a sample, usually as a sampling method for isotopic or elemental analysis of a solid sample. ...
Abstract Particle imaging, electromagnetic, ferrographic, and spectroscopic methods were used to evaluate hydraulic oil samples collected from machines known to be generating abnormal wear particles. Analytical ferrography confirmed the presence of large reworked ferrous particles and small rubbing wear particles in the oil samples. ICP emission ...
In 2017, Peak Scientific collaborated in a study with Analytik Jena to determine low levels of Chromium in Biological Samples by ICP-MS using hydrogen as a reaction gas. Chromium is used in many metal alloys used for metal implants. ...
For useful measurement of low abundant isotopes and mass-limited samples, signal enhancement is often required. In addition, sample preparation and/or sample aerosol desolvation may be necessary to reduce or eliminate mass spectral interferences such as oxides and hydrides. This poster will examine the application of MCICP-MS with a desolvating ...

The gold standard metal measurement is Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); however, sample preparation is laborious and expensive. The Xact 625 metals monitor uses non-destructive X-ray fluorescence technology. A built-in sample collection system enables near-real-time trace metal measurements in ambient air. ...
They deliver a continuous and consistent supply of high-purity nitrogen at the required pressure and flow rates to meet the full and varying demands of your laboratory or research facility, including Sample Evaporation, ICP, ELSD, CO2 Analyzers, FT-IR, TOC, GC and LC-MS. ...
The MVX‐7100 L Workstation when paired with a DS‐5 total consumption nebulizer creates a paradigm shift in ICP‐MS sample introduction. It is a long overdue tool for trace element researchers wanting to measure elements at trace levels in microliter sized samples. ...
