If there was an interfering compound but insufficient evidence for the presence of the target analyte (type II), the GC/MS analyst reported the result as a nondetect with a DL equal to the entire peak of the coeluting compounds.
Detection frequencies and concentrations of carcinogenic PAHs varied between the analytes, types of shellfish, testing methods, and agency data sets [see Supplemental Material, Table 2 (http://dx.doi.org/10.1289/ehp.1103695)].
The peak purity factor is ≥980 for the analyte after all types of stress tests, indicating an excellent separation of brimonidine tartrate peak from other impurities.
In order to investigate the influence of the architecture of the polymeric film used as a receptor, we have conducted simulation employing Monte Carlo ballistic deposition method for an analyte with four types of macromolecules: linear, two brushes configurations and star.
The peak purity factor is ≥980 for both analytes after all types of stress, indicating complete separation of both analyte peaks from the stress induced degradation products.
For optimizing the important parameters affecting the extraction procedure, analyte concentration, pH, type of disperser solvent, absorption time, ionic strength effect, type of desorption solvent and desorption time investigated.
The peak purity index for both the analytes after all types of stress conditions was ≥ 0.9999 indicated a complete separation of both the analyte peaks from degradation products.
This particle diameter is called the liberation size and varies with the analyte and the type of material.
