  • Method for detecting the presence of an analyte in a sample
    Publication number: 20030207442
    Abstract: A test device for detecting the presence of a residue analyte in a sample, which test device includes a support strip and a sample-absorbing matrix attached to the support strip. The sample-absorbing matrix has a material for absorbing an amount of the sample. The test device also includes a mobile-phase support for holding a mobile-phase composition. The mobile-phase support is attached to the support strip and in contact with the sample-absorbing matrix. A mobile-phase composition is disposed on the mobile-phase support and has a receptor for binding with the analyte. The mobile-phase composition can be carried in the sample. A stationary-phase membrane is attached to the support strip and has a first membrane end in contact with the mobile-phase composition and a second membrane end. The membrane allows lateral capillary flow of the sample from the first membrane end to the second membrane end.

  • Method for detection of an analyte
    Patent number: 6475805
    Abstract: A test device, system and method, the device composed of an elongated, toothbrush-shaped, transparent, plastic housing and a lateral-flow test strip for the detection of an analyte, such as a beta-lactam in milk, in the housing, the housing having an expansion cavity to receive expanded, liquid-contacted, absorbing material in the test strip, and to control lateral flow rate and times in the test strip.
