Iain Murray, a statistician based in Washington, says that for a poll to be representative, "matching the sample to the country's demography is absolutely key.
When matching the sample solvent to the mobile phase in terms of elution strength and polarity (e.g. using hexane/ethanol/isopropanol 85/10/5 vol%) and lowering the injection volume to 0.4 μL, the plate count can be increased from 7600 to 21,300 for a low-retaining compound (k′ = 2.3) on a 2.1 mm × 150 mm column (packed with 1.8 μm particles).
Half of the samples (n= 45) were equibiaxially tested within physiological conditions, and the other half, matching the sample location of the mechanical tests, was frozen, cryosectioned, and stained with Picro-Sirius red to differentiate smooth muscle cells, extracellular matrix, and fat.
The four goals of plasma sample pretreatment for HPLC MS analysis, i.e. removal of proteins, removal of other low-molecular interferences, preconcentration of the analytes of interest, and matching the sample solvent with the HPLC MS system, can be rapidly performed in a very simple step by using the SIPTE method.
As the spot size decreases to a size matching the sample device, the photocurrent I ph reduces to 10 nA(S = 0.8 mAW − 1, G = 6.8 × 10− 4).
We will see, however, that tip separations on a scale matching the sample lattice constant give the new possibility that the two currents will beat against each other.
Matching the samples also minimized bias related to storage time, sampling method, and diagnostic procedures.
The CTVB was assigned to each individual by matching the sampling frame to the local authority council tax register.
Matching the samples means any differences in survey estimates should be attributable to measurement error and not sample composition[ 13].
His DNA matched the sample from the skeleton.
The correct alternative is the one that matches the sample.
