"sample zone" is a commonly used phrase in English and can be used in a variety of contexts.
For example, "The store was offering free samples in the sample zone."
If to each slug corresponds a processed sample zone, carry-over can be efficiently exploited.
On-line concentration strategies, namely pH junction and sweeping, were employed to avoid sample zone diffusion at the interface.
For the two-zone stack, a 10-μL reagent zone was aspirated followed by a 40-μL sample zone.
A sandwiched sample zone between a leading and a terminating electrolyte zone was formed in the channel intersection in less than 1 s.
The proposed methodology was based on the difference between the refractive indices of the sample zone and of the carrier stream.
The reproducibility of the μPAD fabrication for hydrophilic channel width of the test zone and sample zone was 1.48% and 6.30%, respectively.
We utilized RIM experiments to investigate wide sample zones created by strong sample solvent, and subsequent gradient zone focusing for a series of compounds.
Spectra 2, 3, and 4 are very similar to each other, despite their correspondence to different zones of the sample (zones 2, 3, and 4).
In this way the spacing between consecutive bands of interest can be physically increased, allowing precise isolation of spatially close sample zones.
After collection of the target fraction the separation mode is resumed, and the separation/collection cycle is repeated until all desired sample zones are separated and captured.
A method-of-moments formulation has been used to numerically evaluate the Taylor Aris dispersivity of sample zones under these conditions for thin electrical double layers applicable to a majority of microfluidic assays.
