Sentence examples for separations were obtained from inspiring English sources
Improved separations were obtained suggesting a favourable effect of ion-pairing interactions between analytes and the additive; however, it remained impossible to separate them all in one run.
The best separations were obtained using monoliths modified with 15, 20, and 30 nm nanoparticles since these sizes produced the most dense coverage of pore surface with gold.
The best separations were obtained within less than 30 min employing a 10 mmol/l phosphate buffer, pH 2.8, 18 °C, 15 kV voltage.
Preparative thin-layer chromatography (TLC) separation was performed on 0.7 mm silica plates (Merck Kieselgel 60 GF254) and chromatographic separations were obtained with 70 230 mesh silica (Merck), by using n-hexane/dichloromethane mixtures.
We evaluated sample injections from buffers with varied ionic strengths and found that efficient stacking and separations were obtained in both low and high conductivity buffers, including physiological buffer with at least 140 mM salt.
When these conditions were compared with those of the CEC optimisation, we can see the potential of using CLC as a chiral separation technique since less chiral selector was used, faster separations were obtained and better repeatability was observed in comparison with its electrical-driven counterpart.
Drager and Regnier have reported that optimum selectivity for some oligonucleotide separations was obtained with materials that were 40 60% quaternized.
At high flow rate, rapid elution and high peaks with insufficient separation were obtained.
Moreover high recoveries and good separation were obtained when natural organic matter (NOM) up to 30 mg/L mixed with AgNPs in ultrapure water.
The best peak height, peak asymmetry, and resolution values for flavonoid and isoflavone detection and separation were obtained by using the lowest pH mobile phase (Fig. 1b).
Twenty-seven cells of this type were identified (between seven and 13 per rat), and z-series (0.5 µm z-separation) were obtained through the dendritic tree of each of these neurons.
