“…Particle sizes lower than 10 μm were tolerated [55]. In contrast, particle size independent sample preparation has been preferred [56] since the presence of particles with sizes as low as 7 μm was claimed to decrease the atomization efficiency [57].…”

“…Only Fe showed a significantly low recovery of 64.48 %. This is may be attributed to iron suspended particles larger than 14 µm experience excessive gravitational settling rates or removal by impaction onto chamber walls, especially in the region of bends or turns in the walls [12].…”

Slurry nebulization technique has been applied for elemental analysis of plant leaves by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The procedure based on dispersing the sample powder (particle size <32 µm) in a dispersing agent (Triton X-100) in an acidic medium, followed by direct nebulization of the suspension into the ICP. The procedure was applied for the determination of Ba, Cd, Cu, Fe, Mn, Ni, Pb, Sr, Ti & Zn in fourteen plant leaves samples. Recoveries were determined by comparing the results obtained using slurry nebulization with results for elemental determination using acid digests of the samples. The procedure yields recovery varies between 85.7% to 99.5% for the most elements.

“…The degree of component wear is ascertained by determining the concentration of generated metallic particles present in the used lubricating oil. Although spectrometers perform a rapid analysis of wear metal particles, the accuracy of the analysis is particle-size dependent (1)(2)(3)(4)(5). To enable the spectrometers to perform particle size independent analyses, ensuring accurate component wear evaluations, several procedures have been published which incorporate acid dissolution of the metal particles before analysis (6)(7)(8)(9).…”

In lubricating oils and hydraulic fluids by atomic emission spectrometry and atomic absorption spectrophotometry is presented. Improved analyses of Ag, Cd, and Na were also accomplished. Metal powder suspensions In hydraulic fluids and lubricating oils were reacted with a small amount of an add mixture containing hydrofluoric, nitric, and hydrochloric acids and analyzed by a DCP emission spectrometer. The recoveries of Al, Cr, Cu, Fe, Mg, Mo, NI, Pb, SI, Sn, TI, and Zn ranged from 89% to 102% with relative standard deviations from 2% to 12%. In addition to the metal powder suspensions, aircraft, automobile, and diesel truck engine oils and aircraft hydraulic fluids were analyzed by atomic emission spectrometry and flame atomic absorption spectrophotometry.
