n a l y s i s 7 6 The innovative iCAP 7000 Series ICP-OES is driven by a so tware solution to simpli y the user experience and improve e iciency. The shared plat orm approach provides control across both the iCAP 7000 Series ICP-OES and ...
This paper considers the features of determining the total tin content in waters with different salinity. Direct ICP-spectrometric analysis of sea waters with a salinity of more than 6‰ significantly reduced the analytical signal of tin by 70% (ICP-MS) and 30% (ICP-OES). The matrix effect...
All of these results, i.e., mean concentrations of elements (n = 3) with their SDs (both determined and certified), as well as the tcalculated values, are collected in Table 1. Table 1. The results of analysis of NIST SRM (1568b, rice flour) using ICP OES. The values of the ...
The surface functional groups were found to contain NH and C=N groups. The XRD analysis confirmed the crystalline structure of the prepared SSC-MOFs. The application for the process of microextracting the arsenic(III) for preconcentration was achieved with superior efficiency. The optimum conditions...
