Atomic emission spectrometer, inductively coupled plasma

Recently it has been shown that rotating coiled columns (RCC) can be successfully applied to the dynamic (flow-through) fractionation of HM in soils and sediments [1]. Since the flow rate of the extracting reagents in the RCC equipment is very similar to the sampling rate that is used in the pneumatic nebulization in inductively coupled plasma atomic emission spectrometer (ICP-AES), on-line coupling of these devices without any additional system seems to be possible. 

The chemical composition of the samples was determined using an inductively Coupled plasma atomic emission spectrometer (ICP-AES) JY 38 from Jobin Yvon. Specific surface area values were determined by BET method using a Micromeritics Instrument Corp. FlowSorb 2300. The basicity of the materials was studied by temperature programmed desorption (TPD) of C02 used as a probe molecule. The equipment was described in a previous work [7]. FTIR spectra of pellets pressed at 2.5xl08 Pa were recorded with a Vector 22 spectrometer from Brucker. The samples were diluted with KBr (lOOmg KBr - 1.5mg of the sample). 

The instrument which uses this plasma torch is called an inductively coupled plasma atomic emission spectrometer (ICP-AES) or an inductively coupled plasma optical emission spectrometer (ICP-OES). It is similar to an...

Color Plate 23 Polychromator for Inductively Coupled Plasma Atomic Emission Spectrometer with One Detector for Each Element (Section 21-4) Light emitted by a sample in the plasma enters the polychromator at the right and is dispersed into its component wavelengths by grating at the bottom of the diagram. Each different emission wavelength (shown schematically by colored lines) is diffracted at a different angle and directed to a different photomultiplier detector on the focal curve. Each detector sees only one preselected element, and all elements are measured simultaneously. [Courtesy TJA Solutions, Franklin, MA.J... 

Thompson and Zao [170] have described a solvent extraction-inductively coupled plasma atomic emission spectrometric method for the determination of down to 0.02 - 0.03 xg/g of molybdenum in soils. The soil sample is pressure-leached with 6 M hydrochloric acid and at 120 °C for 15 minutes. The digest is then extracted with heptan-2-one to separate molybdenum from potentially interfering elements such as iron, aluminium, calcium and magnesium. This organic extract is then directly sprayed into an inductively coupled plasma atomic emission spectrometer operated at 1.65 to 1.7 kW power.

Procedure Use an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES), or equivalent instrumentation with similar capabilities. Follow the instrument manufacturer s instructions for setting instrument parameters for assay of cadmium. Select appropriate background correction points for the cadmium analyte according to the recommendations of the instrument manufacturer. Select analytical wavelengths to yield adequate sensitivity and freedom from interference. 

Characterization of materials was achieved by powder X-ray diffraction, using a Siemens D500 diffractometer, and by scanning electron microscopy. Elemental analysis of pure single phase materials was carried out using a Jarrel Ash Inductively Coupled Plasma Atomic Emission Spectrometer. 

Much more sensitive and less time-consuming techniques such as mass spectrometry, atomic emission, and atomic absorption are needed for the analysis of pollutants. Detectors such as graphite furnace-atomic absorption spectrometer (GF-AAS), inductively coupled plasma-mass spectrometer (ICP-MS), or inductively coupled plasma-atomic emission spectrometer (ICP-AES) seem to be ideal candidates for the analysis of trace metals because of their very low detection limits. The high temperatures used avoid the need for tedious digestions in many samples. FFF-gas chromatography-mass spectrometry could perhaps be used in the analysis of particular organic molecules. 

Abstract In an effort to assess the method validation done using ICP-AES in our laboratory for potable water, an Environmental Laboratory Approval Program organized by New York State Department of Health, Wadsworth Center providing the reference material has been undertaken for 14 trace elements and seven other chemical constituents. The certified means for the reference material and the results obtained in our laboratory are compared. The comparisons helped us assess the quality of our work. All the data from the inductively coupled plasma atomic emission spectrometer (ICP-AES) fall into the ranges specified. 

The titanium contents of the resulting catalyst samples were determined with an inductively coupled plasma-atomic emission spectrometer (ICP-AES) (Kon-tron, Germany Model S-35) after HE acid digestion of the solid. N2 adsorption/ desorption isotherms at 77 K were obtained using a Micromeritics ASAP 2020 apparatus. Catalyst crystalline structure was examined by X-ray diffraction (XRD) on a Shimadzu XRD-6000 diffractometer with Cu Ka radiation. X-ray photoelectron spectroscopy (XPS) data were acquired on a VG Microtech MT-500 spectrometer using A1 Ka X-ray radiation (1,486.6 eV). Fourier transform infrared (FUR) data were obtained on a Shimadzu IR Prestige FUR spectrophotometer. 

The focus of most standardized grease testing has been upon performance and appearance, rather than determining the concentration of chemical components. In part, this is likely due to the relative volume of grease demand when compared to other lubricants. But the primary reason may be that grease is a rather difficult matrix with which to work fi om the perspective of the analytical laboratory. Lubricating oil may be diluted in a solvent and introduced directly into an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) for rapid elemental measurements. Grease, on the other hand, does not dissolve in any common laboratory solvent that is compatible with ICP-AES. 

The measurements were performed using a Thermo Elemental IRIS Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). A 2 kW crystal-controlled radio frequency (RF) generator operating at 27.12 MHz powers the plasma source. An Echelle optical system with a 381-mm focal length diffracts the light from the plasma source before it is focused onto the Charge Injected Device (CID) camera detector [4].

Part III provides several conventional, environmental evaluation processes for surface finishing. In chapter The Necessity and Meaning , we describe the necessity and meaning of enviromnental evaluation for surface finishing. Also we discuss evaluation processes that have already been used. In chapter Frequently Used Evaluations for Effluents , the Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) and the Inductively Coupled Plasma Mass Spectrometer (ICP-MS) are mainly described and discussed as conventional, but powerful analytical tools. In chapter Frequently Used Evaluations for Aerial and Solid Pollution , the conventional analyses for aerial and solid pollution are presented. These types of pollution have caused very serious problems. Therefore, various countermeasures have been devised for them. And even nowadays, new problems such as air pollutants called particulate matter are emerging. These air pollutants include solid particles and liquid droplets that come in various sizes. The small particles that are 2.5 pm or less are called PM2.5. In this chapter, we also focus oti gas chromatography/ion chromatography from the fundamental viewpoint. In chapter Dissolution Assay , the dissolution assay process is described. This type of analysis is used to measure the dissolution amounts and characteristics for many kinds of metal components of materials.

Physical methods of analysis normally involve a measurement of a physical parameter other than mass or volume. For example, a water sample suspected of being polluted with hexavalent chromium can be injected into an inductively coupled plasma atomic emission spectrometer (ICP/AES) and the intensity of light given off by the very hot chromium atoms emitted by the sample measured to give the chromium concentration. Or fluoride in a water sample can be determined by measuring the potential versus a reference electrode of a fluoride ion-selective electrode immersed in the sample and comparing that value with the potential measured in a standard F" solution to give the value of [F"].
