When measuring plated metal samples, it is not uncommon for results from inductively coupled plasma (ICP) analysis to be different than results from HDXRF analysis. Take a look at our application note and learn more about: Why do ICP and HDXRF results differ? How can I determine if my sample is plated? How can I minimize the variation in results for plated metals? Application Note ...
Elemental speciation involves the separation and quantification of different oxidation states or chemical forms of a particular trace element. Trace metals exhibit widely different toxicities depending on their elemental species in the environment. On the other hand, inductively coupled plasma mass spectrometry (ICP-MS) is considered to be the method of choice for elemental analysis for several ...
Determine the surface decontamination efficacy of DeconGel® 1101 on stainless steel, carbon steel, aluminum and concrete surfaces contaminated with Iron (II) Chloride (FeCl2) using ICP-OES (Inductively Coupled Plasma-Optical Emission Spectroscopy) following Environmental Protection Agency (EPA) SW-846 Methods 3005A (sampling) and 6010C ...
The effect of age and gender on major, minor and trace element contents in the intact rib-bone of 84 apparently healthy 15?58 year-old citizens (38 females and 46 males) of a non-industrial region in the Central European part of Russia was investigated by Instrumental Neutron Activation Analysis (INAA) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The summary of ...
This study details the the Arsenic problem in ground water from Bangladesh and how the PDV6000plus can be used to monitor the Arsenic levels in ground water wells. Contains comparison data with inductively coupled plasma mass spectrometer (ICPMS) for groundwater samples in Perth, Western ...
Abstract: Matrix-based mass spectral interferences can compromise detection of a variety of transition elements when using quadrupole inductively coupled plasma mass spectrometry (ICP-MS). Example interferences include 35Cl16O+ on 51V+ , 40Ar16O+ on 56Fe+, and molybdenum oxides on all cadmium isotopes except 106Cd. Cell-based quadrupole ICP-MS instruments can reduce such interferences using ...
The present study seeks to elucidate the effect of different electrolytes on the stability of citrate-coated silver nanoparticles synthesized by the reduction of the Ag(NH3)2+ complex via Tollens’ method. Time-resolved dynamic light scattering technique was used to measure the aggregation behavior of the nanoparticles over a range of electrolyte (NaCl, CaCl2, and AlCl3) ...
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 ...
Introduction The Shimadzu ICPE-9820 multi-type ICP atomic emission spectrometer is the ideal instrument for running EPA Method 200.7. The ICPE-9820 permits simultaneous analysis of all elements, at all wavelengths, allowing high-throughput analysis with little need for dilution. The large 1-inch CCD detector with over 1 million pixels measures 110,000 wavelengths. Overflow channels prevent ...
This study characterized a natural adsorbent material, a dacitic tuff, from Aguas Blancas in Zimapan Hgo. by emission spectroscopy of inductive coupling plasma, X-ray diffraction and scanning electronic microscopy. Also, the influences of concentration, contact time, and pH on the adsorption capacity of arsenic (As) on a dacitic tuff doped with MgO by batch technique were assessed. The results ...
Abstract To estimate air pollution snow samples were collected in March 2001 at six sites in the vicinity of the Kostomuksha factory in Karelia. Seventy-two chemical elements and more than 200 individual organic compounds were identified by inductively coupled plasma mass spectrometry (ICP-MS) and gas chromatography mass spectrometry (GC-MS). It was found that the levels of Li, B, Al, Fe, Ni, Cu, ...
A new method has been developed for the determination of rare earth elements (REEs) (Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) in water samples based on preconcentration with a mini-column packed with 6-(2-thienyl)-2-pyridinecarboxaldehyde functionalized Amberlite XAD-4 resin prior to their determination using inductively coupled plasma optical emission spectrometry (ICP-OES). The ...
This study evaluates the time-dependent dissolution of nanosilver (nAg) in common electrolytes and natural waters. nAg was synthesized via Tollens’ method using sodium citrate as stabilizer; its morphology, UV–Vis spectrum, and particle size were characterized. The dissolved silver was monitored over time using filtration, centrifugation, and inductively coupled plasma atomic ...
Trace metals are found at low concentration in the ambient environment and are associated with adverse health effects. 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 ...
Nanomaterials are used in a wide spectrum of applications, including nanowires that are objects with at least one of its dimensions in the range of 1 to 100 nm. Recently, a new type of silver vanadate nanowire decorated with silver nanoparticles (SVSN‐LQES1) with promising antimicrobial activity against different pathogenic bacteria was described.
