Sentence examples for spiking concentrations from inspiring English sources

As none of the RVS enrichment based methods detected any positive samples in the first test run at the highest spiking level of 9000 cfu/25 g, a re-run was performed with higher spiking concentrations (82,000 cfu and 400,000 cfu/25 g faeces).

The actual spiked (nominal) concentration of MMP-12 in sputum samples for the theoretical spiking concentrations of 800, 3200, and 8000 pg/mL was 910, 3814, and 9217 pg/mL respectively.

The intra-day and inter-day precision (relative standard deviations, n = 4, %) at 0.5 μg/kg and 20.0 μg/kg spiking concentrations were 5.0 9.5% and 3.6 10.0%, respectively.

Lower wet spiking concentrations than those reported here may have resulted in concentration-effect curves.

The NMKL methods (NMKL and Bioline Optima culture) required spiking concentrations as high as 430 000 cfu/25 g before they were able to detect salmonella in any sample.

The Bioline Selecta culture method also had problems and required spiking concentrations as high as 3800 cfu/25 g until the method was able to detect any positive sample.

The spike recoveries were calculated by comparing this known spiking concentration with the concentration determined in unspiked samples by internal standard calibration.

The Ag concentrations of the prepared AgNP suspensions were higher than we had previously achieved and therefore higher than the nominal spiking concentration.

Percent reduction is reported as CFU remaining per original spiking concentration.

Then the method accuracy and precision were expressed as the average value and the relative standard deviations of the ratio of the calculated concentration relative to the expected concentration for each spiking concentration.

Therefore, there are altogether 34 unique labeled and spiked 50 mers against a human cRNA background for each of the spike concentrations.
