Method of analyzing multiple sample simultaneously by detecting absorption and systems for use in such a method

A method of analyzing multiple samples simultaneously by absorption 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) irradiating 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 one or more of said at least one absorbing species with a detection means that is line with the light source and is positioned in line with the parallel to the planar array of multiple containers at a distance of at least about 10 time a cross-sectional distance of a container in said planar array of multiple containers measured orthogonally to the to the plane of the planar array of multiple containers,
• 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.
