Inductively coupled plasma ICP emission

Inductively coupled plasma (icp) emission, direct current plasma (dcp), and inductively coupled plasma mass spectrometry (icp/ms) have taken over as the methods of choice for the simultaneous detection of metallic impurities in hafnium and hafnium compounds (29,30). 

Potassium is analyzed in chemicals that are used in the fertilizer industry and in finished fertilizers by flame photometric methods (44) or volumetric sodium tertraphenylboron methods (45) as approved by the AO AC. Gravimetric deterrnination of potassium as K2PtClg, known as the Lindo-Gladding method (46), and the wet-digestion deterrnination of potassium (47) have been declared surplus methods by the AO AC. Other methods used for control purposes and special analyses include atomic absorption spectrophotometry, inductively coupled plasma (icp) emission spectrophotometry, and a radiometric method based on measuring the radioactivity of the minute amount of the isotope present in all potassium compounds (48). 

In addition, a dealumlnated mordenlte was prepared by leaching HM-10 with 0.4 mol dm HCl solution at 323 K for 30 hr. After washing with distilled water, this was treated In a sodium acetate solution at 353 K for 20 hr for the Ion-exchange. The resulting composition of aluminum was measured by Inductively coupled plasma (ICP) emission spectroscopy after digestion In HF. 

Contamination of the analytes from the carriers (the precipitates) should be first examined, and the blank test carried out carefully. Great care should also be taken in terms of the recoveries of the analytes, because the procedures in the coprecipitation are sometimes time-consuming and irre-producible. Some efficiencies of recovery for Zr(IV) coprecipitation along with the determined values of trace elements in seawater are summarized in Table 7, where inductively-coupled plasma (ICP) emission spectrometry was applied for the simultaneous multielement analysis [45]. In this experiment, 10 mg of Zr(IV) was added to 11 of seawater, the precipitation made... 

Clinical measurements of lithium may be performed using atomic absorption spectrometry (AAS) or flame emission spectrometry (FES) 64). AAS is regarded as the more reliable of the two techniques for blood lithium. FES is rather more sensitive, but suffers from interference from the high sodium and potassium concentrations in blood. Recent developments include inductively coupled plasma (ICP) emission spectrometry, electrothermal atomization atomic absorption spectrometry (ETAAS), and spectrofluorimetric methods. Spectrofluorime-try and ETAAS offer greater sensitivity than the traditional methods and are useful research tools 65, 66). 

The LPR method as a technique for the preconcentration and separation of elements allows generally the development of hyphenated techniques. One example is the combination with the inductively coupled plasma (ICP) emission spectrometry. The general application of the LPR method for the LPR-ICP technique is illustrated in Figure 20.

Inductively coupled plasma (ICP) emission techniques can be used to measure selenium concentrations in air. ICP techniques offer multielement capabilities, but instrumentation is costly and background interference can be a problem (Koirtyohann and Morris 1986). The NIOSH-recommended method for determining selenium in air is inductively coupled argon plasma atomic emission spectroscopy (NIOSH... 

Among the various types of atomic spectroscopy, only two, flame emission spectroscopy and atomic absorption spectroscopy, are widely used and accepted for quantitative pharmaceutical analysis. By far the majority of literature regarding pharmaceutical atomic spectroscopy is concerned with these two methods. However, the older method of arc emission spectroscopy is still a valuable tool for the qualitative detection of trace-metal impurities. The two most recently developed methods, furnace atomic absorption spectroscopy and inductively coupled plasma (ICP) emission spectroscopy, promise to become prominent in pharmaceutical analysis. The former is the most sensitive technique available to the analyst, while the latter offers simultaneous, multielemental analysis with the high sensitivity and precision of flame atomic absorption.

Laser and inductively coupled plasma (ICP) emission spectroscopy constitute powerful multielement qualitative and quantitative tools for the analysis of metals, paints, and glass. Finally, ICP with mass spectrometry (MS) makes an increasing impact on the analyses of trace evidence from pollution source determination to traditional trace exploitation. 

All chemicals were reagent grade and were used without further purification. Infrared spectra were recorded on a JASCO FT/IR-350 spectrometer. Mass spectra were measured using a JEOL JMS-TIOOLP. Elemental analyses were performed on a Yanaco CHN corder MT-6. Inductively coupled plasma (ICP) emission spectroscopy was performed on a Shimadzu lCPE-9000. Thermogravimetric analyses were performed on a MAC TG-DTA 2000 in an argon atmosphere at a heating rate of 1 °C min . ...
