Sentence examples for longer gradient from inspiring English sources
This could possibly be attributed to the lower peak heights for longer gradient times.
After this optimum, the PPR decreases as the PC approaches a plateau for longer gradient times.
PC increases rapidly for short gradients and appears to level off, approaching a maximum at longer gradient times (Fig. 2).
The use of longer gradients also leads to an initial improvement of the protein identification score, but the score seems to have a maximum at longer gradient times.
The longer gradient method 3 was developed for LC-Q-TOF-MS analysis to confirm the structures of HT2-3 O- β-Glc and T2-Glc in comparison with standards.
The application of another chromatographic method with the longer gradient (gradient method 3) showed that there was only one high metabolite peak which eluted at the same time (15.8 min) as the standard.
MASCOT scores are also higher for the long column and increase with longer gradients.
However, if the sample is more complex, the use of longer columns is more attractive as longer gradients are necessary to achieve sufficient separation.
Additionally, in RP methods, lipid elution requires longer gradients and can span a wide range of the chromatographic run, which could affect the detection of smaller molecules.
Complete chromatographic separation of the four example peptide dimers is problematic, even with the longer elution gradient used for peptide mapping in Figure 1 and overlapping elution profiles were observed for the rapid gradient of HDX MS measurements.
Several recent reports of separations at subzero Celsius emphasize the promise for retaining more deuterium and using a much longer chromatographic gradient or direct infusion time.
