The robustness of the method were determined by minor deliberate changes in different experimental parameters and studied their effects on
retention time, peaks resolution, peak area and height.
LC
retention time, linearity of standard calibration curves, validation by regression coefficient, relative standard deviation (RSD, %), limit of detection (LOD; pmol on column) of the method are shown.
We found that when the sample contained 2% TCA with a 5 [micro]L injection volume, longer
retention time of TBM was observed (Supplementary Material Figure S2).
Therefore, according to the presented data, it can be inferred that the constructed wetland for this study are capable of removing the insecticide chlorpyrifos from the aqueous medium, with efficiency exceeding 99%, at a
retention time of 24 h.
For the predicting of the
retention time of Malathion in high-performance liquid chromatography (HPLC), it must begin by analyzing different experimental chromatograms with known conditions and with similar molecules, in addition to the optimization of the molecule to be analyzed (Fig.
Once an organization establishes a product life, it can use that product life, plus any additional time it requires, and have a straight
retention time instead of one based on a "life of product" trigger event.
Antibiotics were identified and quantified irrespective of peak area of samples and calculation was carried out irrespective of antibiotic standard curve by comparison of
retention time and UV absorbance at an optimum point of the standard.
Hbs are identified on the basis of
retention time that is defined as the time in minutes from sample injection to the maximum point of the elution peak.
Mean
retention time was 133 days (n = 59, range = 18-401, SD = 101; Table 1).
Unlike traditional continuous mixers, the
retention time of the mixture in the Combimix system can be regulated within broad limits --from less than 30 to more than 100 seconds.
The main idea of this type of experiments in computer-assisted method development is to provide practically reasonable
retention time values for target compounds.
The samples were collected from each digester after completion of the respective
retention time periods and analyzed (Table-2).
