Sentence examples for between samples and standards from inspiring English sources
To minimize analytical errors, amplitudes of ion beams were matched between samples and standards by regulating amounts of the analyses introduced into IRMS.
We believe that is because large differences in the void volume between samples and standards in the previous analysis (conducted by HPLC-UV−vis, not IC) altered the baseline near the oxalic acid peak.
The amount of cDNA in the three samples was estimated by comparing critical threshold (Ct (dR)) values between samples and standard curves prepared from plasmids containing each transcript (Tables 2 and 3).
This approach can be used to further improve the accuracy of the quantification results, since the influence of remaining differences between sample and standard can be minimized.
The response of the internal standard (Ir) was constant over each measurement session (5% relative standard deviation, no temporal trend), and no difference in Ir-response between samples and calibration standards was observed.
For all control samples, differences between experimental samples and standards were never statistically significant (P < 0.05).

In our experiments, we set t to the mean pairwise distance between samples, and u to the standard deviation of the pairwise distances.
First, the chemical compatibility between sample and internal standard has been checked by acquiring a proton spectrum and, where required, a P NMR spectrum of the mixture right after preparation and again after 24 h.
Hamming approach degree is defined to the similar degree between the undetermined samples and standard samples, and the greater its value indicates that the undetermined samples are closer to the standard samples, that is to say, the undetermined samples and the standard samples are owned to the same class.
