Sentence examples for mixtures at trace from inspiring English sources

This process has particularly unique and adequate features to remove volatile compounds present in liquid mixtures at trace levels.

New methodologies are therefore highly demanded for the quantitative analysis especially for the compositional analysis of chemical mixtures at trace levels by SERS.

We report here a "triangle-rule" based on the principal component analysis (PCA) of surface-enhanced Raman scattering spectra, to calculate the composition of individual component of ternary chemical mixtures at trace levels, which can be simplified into the "balance-rule" for binary mixtures.

In this study, we reported a simple method to calculate the compositions of ternary and binary chemical mixtures at trace levels by the PCA of the SERS spectra, which has been used previously to identify qualitatively the components in chemical mixtures.

Therefore, we really should not be surprised by reports that anthropogenic impacts on receiving waters can include inadvertent up- or down-regulation of receptor-mediated pathways in aquatic organisms exposed to these complex mixtures, even at trace levels.

This study may provide a promising way to do quantitative analysis of chemical mixtures using SERS at trace levels.

Each dust sample was spiked with 250 ng of the following Surrogate Recovery Standards SRSS) that are not found in commercial flame retardant mixtures or are at trace levels (LaGuardia et al. 2006): BDE-126 [5 bromine (Br)], BDE-177 (7 Br), BDE-195 (8 Br), and C12 BDE-209 (10 Br).

Therefore, at the present time, only the previously described targeted sequencing approach can be applied on GM mixture containing GMO at trace level within reason.

In addition, we also find that the modified equation based on the difference of isosteric heats (i.e. DIH equation) can predict the selectivity of trace sulfur gas mixtures at zero pressure satisfactorily.

Surface-enhanced Raman scattering has been proven a powerful means in the fast detection and recognition of chemicals at trace levels, while quantitative analysis especially the compositional analysis of trace chemical mixtures remains a challenge.

Trace constituents are widely present in complex mixtures, and trace analysis is challenging because of the unpredictable matrix.
