Abstract:
A method of analyzing multiple samples simultaneously by abosorption detection, in the absence of a mask or slit which method comprises:(i) providing a planar array of multiple containers, each of which contains a sample comprising at least one absorbing species, (ii) irradating the planar array of multiple containers with a light source comprising at least one wavelength of light that is absorbed by one or more of said at least one absorbing species, the absorption of which is to be detected, and (iii) detecting absorption of light by the one or more of said at least one absorbing species with a detection means that is in line with the light source and is positioned in line with and parallel to the planar arrary of multiple containers at a distance of at least about 10 times a cross-sectional distance of a container in said planar array of multiple containers measured orthogonally to the plane of the planar array of multiple conatiners wherein the detection of absorption of light by a sample in the planar array of multiple containers indicates the presence of an absorbing species in said sample.
