Sentence examples for correction for retention from inspiring English sources

Nucleotide ratios were calculated from peak areas after correction for retention times.

A TSQ Vantage triple-quadrupole mass spectrometer (Thermo Fisher Scientific, San Jose, CA) was utilized for the scheduled LC-MRM analysis with on-the-fly correction for retention time (RT) shift.

The model compounds used in this study and their typical interactions are listed in Table  1.> Determination of McReynolds constants requires that Kovats indices (Eq.  1) are calculated based on the adjusted retention times (correction for hold-up retention time) of a number of n-alkanes and model compounds.

In our experience, we found that employing two reference peptides as retention time markers is sufficient for systematic correction of retention time, whereas too many reference peptides may adversely affect the real-time detection window adjustment by the interference from complex sample matrices.

Thus, without the on-the-fly correction of retention time shift, the transitions of these two peptides would not be captured in the predicted retention time window.

Matrix and buffer samples were supplemented with 13 internal standards for retention index correction (C8-C30 facid acid methyl esters) as previously reported [31].

The XCMS analysis methodology involves peak picking/filtering and matching these peaks across samples for retention time correction.

To correct for systematic retention time shift during the scheduled LC-MRM analysis, we incorporated an on-the-fly correction in our MRM detection workflow, during which the instrument automatically detects the shift in retention time for predefined reference peptides and adjusts, in real-time, the retention time window for subsequently eluted targeted peptides.

Below the diagonal: P-values adjusted by Bonferroni correction for the differences in marker retention between two techniques.

Primary metabolite data analysis was performed using ChromaTOF software version 4.41, which supports automatic deconvolution of all mass spectra from a chromatogram, built in mass-spectral correction for co-eluting metabolites, calculation of retention indices, and identification of a suitable fragment mass-to charge ratio for selective quantification.

Measures exist for the correction of water retention between HD sessions that result in IDWG and edema following fluid and food intake.
