“…All analytes were below their respective LOQ values for all samples analyzed. This pattern was also observed in previous studies with commercial drug samples in solid dosage form 26,27,31,[33][34][35] . Consequently, all samples are within the limits recommended by the USP Chapter insert, i.e., lower than 10 g day -1 for tablets drugs.…”

“…Taking into account the low target limits for elements from class 1 4,6 , Table 5 summarizes analytical methodology previously reported for Cd, Hg and Pb determination in pharmaceutical samples using ICP OES. Considering MDD of 10 g day -1 , the LOQ values obtained for Cd 26,31,32 , Hg 26 and Pb 26,[31][32][33] were higher than 0.3J (i.e., LOQ established by USP). As it can be noted, none of the aforementioned analytical methods meet the USP requirements for these three analytes at the same time.…”

“…ICP‐AES is a type of emission atomic spectroscopy technique which uses an Ar plasma energy source to produce excited atoms and ions capable of emitting light at discrete wavelengths. ICP‐AES is commonly used when funds are limited since it presents a significant advantage of less costly instrumentation as compared with other multi‐element techniques (Zachariadis and Michos 2007). A possible disadvantage of the ICP technique is the destructive sample preparation method prior to actual analysis (Smodis 2007).…”

Particle-induced X-ray emission (PIXE) and ICP-AES can be combined to obtain a wider range of detected elements, augment previous data and ⁄ or to verify measured concentrations of heavy and trace metals in geological samples. Intercomparison of data sets generated by multiple techniques is challenging due to the differing processes and methods of each technique. Here, we compare elemental data obtained by both techniques for aeolian dust from Owens (Dry) Lake, California. Nineteen elements were detected by PIXE, sixteen by ICP-AES and ten elements were detected by both techniques. Statistical analyses of data set groupings illustrated which parameters differed significantly between PIXE and ICP-AES. Relative variation (%) showed that PIXE gave higher concentrations than ICP-AES for Al, As, Cu, Fe, K, Mn, Ni, Sr, Ti and Zn in all samples. For As, Cu, Sr and Zn, relative variation was variable between the techniques. PIXE detection limits exceeded ICP-AES concentrations for Ba, Cd, Co, Cr, Pb and Mo. Low ICP-AES percentage recoveries of Al, Fe, K, Mn and Ti for NIST SRM 2710 indicated incomplete dissolution during digestion (EPA Method 3050B), since elements were bound in silicate structures. Variability between the two data sets is explained by differences between analytical techniques, sample preparation methods and ⁄ or variability in sample matrices.

“…In addition, higher slurry concentrations may induce severe clogging of the supply tubes as well as nebulizer, which results in frequent cleaning necessity. High amounts of organic mass may also extinguish the plasma resulting in worsening its stability [12] and lowering its temperature [13]. These plasma parameters affect atomization and excitation efficiency of analytes and thus the results of the analysis.…”

Carbon nanotubes (CNTs), due to their special structure and unique properties, are still one of the most interesting materials for scientists. Recently, carbon nanotubes were proposed as a new type of carbon support for catalysts. Fe, Pt, Ni, Co, and other metals anchored to CNTs are used in various reactions. Due to the fact that production processes are usually unpredictable and the total amount of metal/metal oxide deposited on the CNTs may only be estimated, the methods for examining the chemical composition are necessary. In this study, fast and simple inductively coupled plasma atomic emission spectrometry (ICP-AES) with slurry nebulization was proposed for metal content determination in hybrid CeZrO2/CNT, Ni-CeZrO2/CNT, and Ni/CNT materials. Slurries were prepared by 30 min ultrasonication of appropriate amount of investigated material in 1% Triton X-100 solution. Optimal range of slurry concentration and optimal RF plasma power were established (40–400 mg L−1, 1.2 kW, resp.). Obtained results proved that this method may be applied for determination of Ce, Zr, and Ni in hybrid CNT-based materials.
