Isotachophoresis

We show that the response of the detector is linear with the initial analyte concentration, making this device suitable for quantitative analysis. If present in jsotachophoresis amounts, onstrumentation analyte ions can displace all electrolyte coions, reaching a plateau concentration.

We also demonstrate the use of our simulation tools for design and prediction of ITP assays, and validate these results with a demonstration of multiplexed indirect detection of unlabeled analytes performed using the device.

Please help improve this article by introducing citations to additional sources. Indeed, plateau mode ITP separations are readily recognized by stairlike profiles, each plateau of the stair representing an electrolyte or analyte zone having from LE to TE increasing electric jnstrumentation and decreasing conductivities.

Using this device we demonstrate focusing and detection of a fluorescent species with a limit of detection of pM.
