Sentence examples for trace concentrations in from inspiring English sources

UAE-MSC is a novel technology to determine organic compounds present in trace concentrations in particulate matter.

This is probably because the adsorption process is cheap to operate and flexible to maintain, and it also generates a high quality effluent, even when metal ions are in trace concentrations in the feed wastewater (Fu and Wang 2011).

Flame atomic absorption spectrometry (F-AAS) is among the most widely used methods for the determination of the heavy metals at trace levels, but the sensitivity and selectivity of F-AAS is usually insufficient for the determination of heavy metals at trace concentrations in complex matrix environmental samples [11 13].

The exploration begins with a visually-based qualitative stratigraphic description of all metals determined by ICPMS studies to be present at more than trace concentrations in a complex sedimentary sequence in an exposure of surficial deposits in the wadi-floor, a process that also suggests further anomalies and uncertainties in existing understanding.

These mono-lipidic RLs were also detected in trace concentrations in continuous P. aeruginosa cultures (Gruber et al. 1993).

Understanding toxic and favorable interactions of metal species with living organisms requires basic information on quantities and chemical characteristics of complexes at trace concentrations in biological materials.

The direct determination of toxic metal ions, in environmental samples, is difficult because of the latter's presence in trace concentration in association with complex matrices, thereby leading to insufficient sensitivity and selectivity of the methods used.

The reference element is assumed to have little variability of occurrence and is present in trace concentration in the examined environment.

SFWMD and FDEP employ stringent QA/QC programs for mercury collection and analysis due to its ultra-trace concentrations in the environment.

Further, these compounds are generally present at trace concentrations and in complex matrices requiring highly selective and sensitive analytical methods for their measurement.

However, analytical methods cannot directly measure metal ions, in particular at ultra-trace concentration, in aqueous systems due to the lack of sensitivity and selectivity of these methods.
