Elimination of nitric acid interference in ICP-AES by using a cyclonic spray chamber/Nafion membrane-based desolvation system

Sample introduction systems for the analysis of liquid microsamples by ICP-AES and ICP-MS

“…Finally, it is worth mentioning that the use of membrane based desolvation systems are beneficial for mitigating non-spectral interferences in ICP-AES caused by inorganic acids [66,194]. Al low liquid flow rates, for matrices containing acids like hydrochloric and nitric the interferences are eliminated even for concentrated solutions.…”

Compensation of inorganic acid interferences in ICP-OES and ICP-MS using a Flow Blurring® multinebulizer

“…39 were operated with a different spray chamber and, as reported by several authors, the type of spray chamber (i.e., double-pass or cyclonic) also plays a critical role in signal reduction induced by the presence of acid. [43][44][45][46] Contrary to ICP-OES, uncertainty values associated with the obtained recovery values were independent not only of the acid tested and the introduction system used but also of the acid concentration. As noted, higher uncertainty values were obtained in ICP-MS measurements compared to ICP-OES, ranging from 3 to 8%.…”

The Separation of Beryllium from Selected Elements Using the Dipex®Extraction Chromatographic Resin

“…This phenomenon is frequently observed in ICP-AES. [10,11] The beryllium concentrations determined by ICP-AES were, therefore, normalized to the 4.0 M HNO 3 matrix used for the ICP-AES calibration standards by using the data in Table 4.…”
