Abstract

Automated fluid handling system comprising a housing and two or more fluid handling units arranged as interchangeable modular components with an external fluidics section and an internal non fluidics section, and wherein the housing comprises a liquid handling panel with two or more of component positions for receiving said interchangeable modular components such that the external fluidics section is separated from the non fluidics section by the liquid handling panel.

Abstract

The present invention provides a method of assaying a sample solution for the presence of a first analyte comprising: (a) providing a sensor surface having a ligand immobilized thereto; (b) flowing the sample solution over the sensor surface; and (c) detecting the presence or absence of binding of the analyte to the ligand on the sensor surface; wherein the contact time between the sample solution and the immobilized ligand is less than 15 seconds.

Abstract

A Surface Plasmon Resonance (SPR) biosensor system comprising: a SPR sensor surface, an illumination unit arranged to direct a wedge shaped beam of light at a line shaped detection area on the SPR sensor surface transverse to the direction of propagation of light, and a detection unit with detection optics for directing light reflected from the SPR sensor surface onto a two-dimensional optical detector unit such that the angle of reflection is imaged along one dimension and the width of the detection area along the other, wherein the illumination unit is arranged to selectively direct the wedge shaped beam of light at two or more spaced apart line shaped detection areas on the SPR sensor surface transverse to the direction of propagation of light.
